And here is okra the underestimated, a vegetable that confounds some Americans with its inner tap of mucilage, a viscous liquid shunned as slime.
|
|
Yet even a plumped-up cactus is not like a cartoon keg that can be tapped for free-flowing water; the water is absorbed into gluey tissue called mucilage that in most cases is not safe to eat.
|
|
It's not merely in the steady (and modern) use of exclamation points but in the sudden turns and reversals, without the mucilage of extended argument—the turn-on-a-dime movements, the interjections, the tone of a man talking to himself and being startled by what his self says back.

Root mucilage is made of plant-specific polysaccharides or long chains of sugar molecules. This polysaccharide secretion of root exudate forms a gelatinous substance that sticks to the caps of roots. Root mucilage is known to play a role in forming relationships with soil-dwelling life forms. Just how this root mucilage is secreted is debated, but there is growing evidence that mucilage derives from ruptured cells.
|
|
To determine the sugars within root mucilage, monosaccharide analysis and monosaccharide linkage analysis are undertaken. Monosaccharide linkage analysis involves methylating the root mucilage, which contains polysaccharides. The root mucilage is hydrolysed using acid to break down the polysaccharides into their monosaccharide components. The subsistent monosaccharides are then reduced to open their rings.
|
|
Glands at the tips of the tentacles "secret a sticky mucilage," an adaptation shared with the rest of the genus Drosera, that prevents the plant from smothering itself in its own mucilage as it waits. The mucilage that each gland produces forms a droplet that attracts insects. When an insect lands on the leaf, it sticks to the mucilage drops and the tentacles close in around the insect and suffocate it. The tentacles and sessile glands then release protease and phosphatase along with other digestive enzymes to digest the insect.

Psyllium has been used as a thickener in ice cream and other frozen desserts. A 1.5% weight/volume ratio of psyllium mucilage exhibits binding properties that are superior to a 10% weight/volume ratio of starch mucilage. The viscosity of psyllium mucilage dispersions are relatively unaffected between temperatures of , by pH from 2 to 10, and by salt (sodium chloride) concentrations up to 0.15 M.

|
The carbohydrates of ulluco are composed mainly of starch. But there is also a significant amount of mucilage, a heterogeneous and complex polysaccharide that is recognized as a type of soluble fiber. The mucilage level varies among tubers, high content gives to the raw tubers a gummy texture. Soaked in water or cut very finely are methods used to remove the greatest amount of mucilage from raw tubes,.
|
|
Plants produce a similar substance called mucilage that is also produced by some microorganisms.
|
|
Individual cells may regulate buoyancy via an ionic pump. Some pennate diatoms are capable of a type of locomotion called "gliding", which allows them to move across surfaces via adhesive mucilage secreted through the raphe (an elongated slit in the valve face). In order for a diatom cell to glide, it must have a solid substrate for the mucilage to adhere to. Cells are solitary or united into colonies of various kinds, which may be linked by siliceous structures; mucilage pads, stalks or tubes; amorphous masses of mucilage; or by threads of chitin (polysaccharide), which are secreted through strutted processes of the cell.

The technology also includes a hydromechanical device to remove floating fruits and light impurities, as well as heavy and hard objects, and a cylindrical screen to remove the fruits whose skin was not separated in the pulping machine. Scientists at Cenicafé discovered that a coffee fruit with mucilage (immature and dry fruits have no mucilage) has enough water inside for the skin and seeds to be separated in conventional pulping machines without water, that the liquid was only required as a conveying means and that pulping without water avoids 72% of the potential contamination. Mucilage removal has been done through a fermenting process, which takes between 14 and 18 hours, until the mucilage is degraded and can easily be removed with water. Washing fermented mucilage requires, in the best case, 5.0 L/kg of DPC.

Several scientists have determined the composition of plant root mucilage using monosaccharide analysis and linkage analysis, showing that Maize (Zea mays) root mucilage contains high levels of galactose, xylose, arabinose, rhamnose, and glucose, and lower levels of uronic acid, mannose, fucose, and glucuronic acid. Wheat (Triticum aestivum) root mucilage also contains high levels of xylose, arabinose, galactose, glucose, and lower levels of rhamnose, glucuronic acid and mannose. Cowpea (Vigna unguiculata) also contains high levels of arabinose, galactose, glucose, fucose, and xylose, and lower levels of rhamnose, mannose, and glucuronic acid. Many other plants have had their root mucilage composition determined using monosaccharide analysis and monosaccharide linkage analysis.

Drosera is one of the largest genera of carnivorous plants, and individual species vary extensively in their specific morphology. Common to all members of Drosera are highly modified leaves lined with tentacle-like glandular trichomes. At the end of each trichome, a bead of highly viscous mucilage is secreted, which resembles a drop of dew. The mucilage is a fairly pure aqueous solution of acidic polysaccharides with high molecular weights, which makes the mucilage not only highly viscous, but also very sticky, so much so, a single drop of mucilage may be stretched to lengths of up to a meter and cover one million times its original surface area.

Mucilage from desert indianwheat (Plantago ovata) is obtained by grinding off the husk. This mucilage, also known as psyllium, is commonly sold as Isabgol, a laxative which is used to control irregular bowel syndrome and constipation.Sangwan et al. (2011). Mucilages and their Pharmaceutical Applications: an Overview.

|
Plants use up to 60% of their energy secreting root mucilage, which they generate from photosynthesis that takes place in the leaves. Root mucilage plays a role in developing a symbiotic relationship with the soil-dwelling fungi. This important relationship is known to affect 94% of land plants, and benefits plants by increasing water and nutrient uptake from the soil, particularly phosphorus. In return, the fungi receive food in the form of carbohydrates from the plant in the form of broken-down root mucilage.

Burdock roots contain mucilage, sulfurous acetylene compounds, polyacetylenes and bitter guaianolide-type constituents. Seeds contain arctigenin, arctiin, and butyrolactone lignans.
|
|
The open ring monosaccharides are then acetylated, and separated typically by using gas chromatography, although liquid chromatography is also used. The masses of the monosaccharides are then detected using mass spectrometry. The gas chromatography retention times and the mass spectrometry chromatogram are used to identify how the monosaccharides are linked to form the polysaccharides that make root mucilage. For monosaccharide analysis, which reveals the sugars that make root mucilage, scientists hydrolyse the root mucilage using acid, and put the samples directly through gas chromatography linked to mass spectrometry.

|
The size of a mature leaf is around 5 to 7.5 cm long and 2.5 cm wide. The diameter of an entire rosette can up to 15 cm. The fleshy surfaces of the leaves are covered with numerous sticky droplets called the mucilage. The mucilage is secreted by the peduncular gland on the top of each stalk.
|
|
Levan production in bacteria is typically a sign of growth in population. There are also possible ways to produce by fracturing soybean mucilage.
|
|
Scientists at Cenicafé developed a machine to remove the mucilage covering the coffee seeds. This machine, called Deslim (the initial letters of the Spanish demucilager, the mechanical washer and cleaner) removes more than 98% of the total mucilage (same as a well conducted fermentation) by exerting stress and generating collisions among beans, using only 0.7 L/kg of DPC. The resulting highly concentrated mixture of water, mucilage and impurities is viscous and is added to the separated fruit skin in a screw conveyor. In the screw conveyor the retention is greater than 60%, which means a 20% additional control of potential contamination.

|
Bast fibre from the stem of the plant has industrial uses such as the reinforcement of polymer composites. The mucilage produced by the okra plant can be used for the removal of turbidity from wastewater by virtue of its flocculent properties. Having composition similar to a thick polysaccharide film, okra mucilage is under development as a biodegradable food packaging, as of 2018.

Most farmers on Sulawesi, Sumatra, Flores, and Papua use the "giling basah" (or wet hulling) process. In this technique, farmers remove the outer skin from the cherries mechanically, using rustic pulping machines, called "luwak". The coffee beans, still coated with mucilage, are then stored for up to a day. Following this waiting period, the mucilage is washed off and the coffee is partially dried for sale.
|
|
This wet appearance probably helps lure prey in search of water; a similar phenomenon is observed in the sundews. The droplets secrete only limited enzymes and serve mainly to entrap insects. On contact with an insect, the peduncular glands release additional mucilage from special reservoir cells located at the base of their stalks. The insect struggles, triggering more glands and encasing itself in mucilage.

On contact with an insect, the peduncular glands release additional mucilage from special reservoir cells located at the base of their stalks. The insect struggles, triggering more glands and encasing itself in mucilage. P. moranensis can bend its leaf edges slightly by thigmotropism, bringing additional glands into contact with the trapped insect.

The droplets secrete limited amounts of digestive enzymes, and serve mainly to entrap insects. On contact with an insect, the peduncular glands release additional mucilage from special reservoir cells located at the base of their stalks. The insect will begin to struggle, triggering more glands and encasing itself in mucilage. Some species can bend their leaf edges slightly by thigmotropism, bringing additional glands into contact with the trapped insect.

Cordia sulcata is known commonly as moral, white manjack, or mucilage manjack. It is a tree that can be found throughout the Caribbean islands from Cuba to Trinidad.
|
|
The characteristic is also reduced or lost for cooked tubers. In South America, ulluco tubers with high mucilage content are popular for soups because they add a thicker texture.
|
|
Most small-scale farmers in Sumatra, Sulawesi, Flores and Papua use the giling basah process. In this process, farmers remove the outer skin from the cherries mechanically, using locally built pulping machines. The coffee beans, still coated with mucilage, are then stored for up to a day. Following this waiting period, the mucilage is washed off and the parchment coffee is partially dried in the sun before sale at 10% to 12% moisture content.

This dark brown, perennial kelp grows from a creeping, branching rhizome which sends up thalli at intervals. The thalli are ribbon-like and grow to a length of about and width of with a smooth surface and entire edges. They grow on short, cylindrical stipes some long and wide containing many mucilage ducts. It is very similar in appearance to Laminaria longipes but that species does not have mucilage glands in the stipes.

The intricacies of dinoflagellate pellicle cysts: the example of Alexandrium minutum cysts from a bloom-recurrent area (Bay of Baiona, NW Spain). Deep-Sea Research Part II: Topical Studies in Oceanography 57: 166–174. These are not pellicle or resting cysts since they are not dormant. Similarly, palmelloid or mucilage stages are not pellicle or resting cysts, but stages in which the monad loses its flagella and becomes enveloped in multilayered mucilage wherein division takes place.
|
|
In semi-washed processing, the cherries are de-pulped to remove the pericarp. After this the slimy mucilage layer which covers the bean is removed. This is done mechanically by feeding the beans into a cylindrical device which conveys them upward. While the friction and pressure exerted on the beans by this process is enough to remove most of the mucilage, a small amount of it will still remain in the centre-cut of the beans.

|
Carnivory in plants appears to have evolved independently in four major angiosperm lineages and five orders: Poales, Caryophyllales, Oxalidales, Ericales, and Lamiales. One common trait found in several Lamiales families that may have led to carnivory is the secretion of proteinase mucilage through leaf surfaces. This mucilage is generally used to prevent insect predation by trapping and degrading potentially harmful insects. Some research suggests these glands can quite easily shift their function from secretion to absorption.
|
|
The two by-products are widely used as worms' substrate to produce natural fertilizers. However, the high concentration of the mucilage obtained from the demucilager provides opportunity for industrializing the by-product.
|
|
One species (Polypodochrysis teissieri) inhabits benthic substates (sometimes found the mucilage of other algae) and is able to produce lorica with one or more tubular necks. The other species live in the plankton.

|
Stir-fried okra with diced chili peppers The products of the plant are mucilaginous, resulting in the characteristic "goo" or slime when the seed pods are cooked; the mucilage contains soluble fiber. One possible way to de-slime okra is to cook it with an acidic food, such as tomatoes, to render the mucilage less viscous. Pods are cooked, pickled, eaten raw, or included in salads. Okra may be used in developing countries to mitigate malnutrition and alleviate food insecurity.
|
|
There was also philosophical calcination, which was said to occur when horns, hooves, etc., were hung over boiling water, or other liquor, until they had lost their mucilage, and were easily reducible into powder.
|
|
With the following monosaccharides determined as well as their linkages, scientists have determined the presence of pectin, arabinogalactan proteins, xyloglucan, arabinan, and xylan, which are plant-specific polysaccharides within the root mucilage of plants.
|
|
There are also other plants that produce a sticky mucilage not necessarily associated with a tentacle or glandular trichome, but instead can be described more like a slime capable of trapping and killing insects.
|
|
Fermentation can be done with extra water or, in "Dry Fermentation", in the fruit's own juices only. The fermentation process has to be carefully monitored to ensure that the coffee doesn't acquire undesirable, sour flavors. For most coffees, mucilage removal through fermentation takes between 8 and 36 hours, depending on the temperature, thickness of the mucilage layer, and concentration of the enzymes. The end of the fermentation is assessed by feel, as the parchment surrounding the beans loses its slimy texture and acquires a rougher "pebbly" feel.
|
|
The leaves contain rutin, mucilage, volatile oils such as limonene and diosphenol (or barosma camphor) also menthone, quercetin, hesperidin, alpha-pinene, calcium, iron, magnesium, manganese, phosphorus, potassium, selenium, silicon, zinc, vitamin B1, B2, B3 and vitamin C.

A D. anglica leaf bent around a trapped fly Like all sundews, D. anglica uses stalked mucilaginous glands called tentacles which cover its laminae to attract, trap, and digest small arthropods, usually insects. These are attracted by a sugary scent exuded by the glands, and upon alighting on the plant adhere to the sticky drops of mucilage. Although most of its prey consists of small insects such as flies, bulkier insects with large wings are also caught. Small butterflies, damselflies, and even dragonflies can become immobilized by the plant's sticky mucilage.
|
|
Phytochemicals in Verbascum thapsus flowers and leaves include saponins, polysaccharides, mucilage, flavonoids, tannins, iridoid and lignin glycosides, and essential oils. The plant's leaves, in addition to the seeds, have been reported to contain rotenone, although quantities are unknown.
|
|
The only species identified in the Mediterranean Sea are O. ovata and O. siamensis. The bloom in 2006 off Sant Andreu de Llavaneres in northeastern Spain, was described as "a conspicuous, thick, brownish mucilage layer covering benthic macroalgae".
|
|
Draparnaldia attaches to the substrate with rhizoids and is composed of erect, branching filaments surrounded by soft mucilage. Branches born in alternating, opposite, or whorls of tufts from the main axis. Chloroplasts tend to be parietal bands (i.e. "barrel shaped").
|
|
Studies of its effects on lactation have shown mixed results. Its safety has not been well studied, however small trials have found no adverse effects in mothers or their babies. The key pharmacologic constituents of shatavari are steroidal saponins, mucilage, and alkaloids.
|
|
Pinguicula gigantea, unlike most Pinguicula species, has sticky upper and undersides of the leaves. The leaves have trichomes on them, which secrete a mucilage that traps prey. P. gigantea's leaves are among the largest in its genus. The species epithet, gigantea, describes this characteristic.
|
|
Excretory idioblasts store oils, lipids, tannins, mucilage, and minerals. They are currently under research for their storage of the important medicinal qualities of plants. Selective culturing of excretory idioblasts allows better harvesting of their stored products. Tracheoid idioblasts strongly resemble tracheids, or water-conducting cells.
|
|
Kent also described a Proterospongia species containing two types of cells embedded in mucilage; however, this is the only account of such a species and it has been suggested that the observed amoeboid cells were actually posterior tentacles that are present on some choanoflagellates.
|
|
The plant's initial response to contact with prey consists of thigmotropic (movement in response to touch) tentacle movement, with tentacles bending toward the prey and the center of the leaf to maximize contact. D. anglica is also capable of further movement, being able to bend the actual leaf blade around prey to further the digestion process. Tentacle movement can occur in a matter of minutes, whereas the leaf takes hours or days to bend. When something gets caught, the tentacles touching the prey exude additional mucilage to mire down the prey, which eventually dies of exhaustion or is asphyxiated as the mucilage clogs its tracheae.
|
|
P. alpina leaf rosette The five to eight fleshy, light-green to reddish, elliptic to lanceolate leaves form a ground-hugging rosette up to 6 cm (2.5 in) in diameter. The upper surface of the leaves are sticky from the mucilage secreted by stalked glands covering the leaf surface. Small insects alighting upon this surface are caught by the mucilage, upon which sessile glands embedded in the leaf surface (except for the central vein) secrete digestive enzymes to digest the prey. The leaves of this species are able to further aid digestion by growing such that the leaf edge rolls toward the center, bringing additional glands into contact with the prey.
|
|
The fruit of lasura start appearing during July–August. It is a kind of a drupe, light pale to brown or even pink in color. The appearance tends to darken when ripening sets in. Being full of viscid glue like mucilage, the pulp is somewhat translucent.
|
|
Sea snot Sea snot or marine mucilage is a collection of mucus-like organic matter found in the sea. The substance is described as "jello-like sheets of disease-carrying mucus" that holds a strong presence in the Mediterranean Sea and has been spreading into farther-flung waters.
|
|
These side branches are divided extensively into terminal hairs. The entire plant is enveloped in loose, slippery mucilage. Draparnaldia is a cosmopolitan genus with wide distribution and it is usually found in cold aerated waters. They are either attached to sand or grow epiphytically on other aquatic plants.
|
|
However, the resin, unlike mucilage, is unable to carry digestive enzymes. Therefore, Roridula species do not directly benefit from the insects they catch. Instead, they form a mutualistic symbiosis with species of assassin bugs that eat the trapped insects. The plant benefits from the nutrients in the bugs' feces.
|
|
Further, B. stevenii is thought to have a larger fruit body size, a more coarsely scaly stipe, and lack of mucilage in the volva and the innermost parts of the stem. The presence or absence of mucilage has been traditionally considered the significant characteristic separating the species. In 1904, Lászlo Hollós proposed the idea of a single polymorphic species; in 1942, Paul Marshall Rea, after studying 25 specimens from southern California, concluded that B. stevenii was conspecific with B. phalloides and represented a single species. An analysis of a number of European specimens—using both macroscopic and microscopic characteristics in addition to molecular analysis of ITS regions of the 5.8S rDNA—also suggested both to be conspecific.

Inflorescences emerge from the leaf axils and bear white, lipped flowers each about long. They are pollinated by insects. This species can escape cultivation and become a weed. Balanguseed mucilage (BSM) features many advantages over most of its polymer counterparts, including a lower production cost, higher efficiency, and better medicinal properties.
|
|
The leaves are capable of secreting limited quantities of a mucilaginous fluid containing polysaccharides. The upper leaf surface has a hair cushion which is also often coated with dried mucilage. The lower surface is covered densely with a thick, white felty covering of lantate hairs. Growth rates are very slow. :S.
|
|
Some xerophytes, such as cacti and other desert plants, have mucilage in their tissues. This is a sticky substance that holds water within the plant, reducing the rate of dehydration. Some seeds and spores remain dormant until adequate moisture is present, at which time the seed or spore begins to germinate.

In 1976, Jiří Komárek defined the prokaryotic cyanobacteria genus Cyanothece as distinct from Synechococcus NAG 1949. Organisms in both genera share characteristics in addition to being oxygenic phototrophs. They are both unicellular, forming aggregates, but not found in mucilaginous colonies. They may have a thin mucilage layer around each cell.
|
|
Sea snot forms when globs of marine snow coagulate into large globs that can span distances as large as 124 miles. The mucilage has many components, including a wide range of microorganisms including viruses and prokaryotes, and exopolymeric compounds with colloidal properties. Sea snot is also produced by phytoplankton when they are stressed.
|
|
The haploid phase begins when the mature organism releases many spores, which then germinate to become male or female gametophytes. Sexual reproduction then results in the beginning of the diploid sporophyte stage, which will develop into a mature individual. The parenchymatous thalli are generally covered with a mucilage layer, rather than cuticle.
|
|
Evening primrose leaves contain flavonoids, mucilage, tannins, sugar, resin and phytosterols. The flowering stems are preferably used when they are still young in June. They have to be peeled and can then be eaten raw or fried. The flower buds are denoted as a delicacy and can be harvested from June to September.

The functions of AGPs in plant growth and development processes rely heavily on the incredible diversity of their glycan and protein backbone moieties. In particular, it is the AG polysaccharides that are most likely to be involved in development. Most of the biological roles of AGPs have been identified through T-DNA insertional mutants characterization of genes or enzymes involved in AGP glycosylation, primarily in Arabidopsis thaliana. The galt2-6 single mutants revealed some physiological phenotypes under normal growth conditions, including reduced root hair length and density, reduced seed set, reduced adherent seed coat mucilage, and premature senescence. However, galt2galt5 double mutants showed more severe and pleiotropic physiological phenotypes than the single mutants with respect to root hair length and density and seed coat mucilage.

It has been described as tasting of marmalade and smelling of roses. Boning (2006) indicates that the flavor is "sweet, aromatic and pleasant, although tangy and slightly astringent in some varieties. It resembles a marmalade made, in part, with citrus and, in part, with tamarind." Numerous hairy seeds are encapsulated in a slimy mucilage.

The cells have other mechanisms of self-defense in addition to colonizing. Scenedesmus can be divided into two subgenera, the non-spiny Scenedesmus and the spiny Desmodesmus. Although spineless, the Scenedesmus subgenera cells have thick cells walls and mucilage, which may make them digestion-resistant. Some chemical compounds in Scenedesmus could even be toxic to certain organisms upon consumption.

2019.1681660 The roots of the plant have been shown to contain up to 10% tannin. A substance similar to adrenaline has been found within the plant's leaves. Mimosa pudica's seeds produce mucilage made up of D-glucuronic acid and D-xylose. Additionally, extracts of M. pudica have been shown to contain crocetin-dimethylester, tubulin, and green-yellow fatty oils.

Lateral budding is present and mucilage, or sap, is excreted from any cut surfaces on the plant body. The plant has a large central medulla and a single vascular bundle containing the xylem, phloem and cambium. Since the organism is slow-growing and xerophilous (i.e. drought-tolerant), only a small conduction channel is needed, unlike other plants.

It is collected from acacia trees in Darfur and Kordofan and used widely in industry for products ranging from mucilage (for postage stamps), to foam stabilizers, to excipient in medicines and dietetic foods. The Gum Arabic Company markets the product, with restraints placed on the right of any private company to independently export unprocessed gum arabic.
|
|
The rosettes are usually submerged under water or produce a layer of mucilage that remains in the cup formed by the dense rosette. Of all other Genlisea species, G. pygmaea is the most closely related when considering morphological characteristics. It differs slightly in habitat by preferring sandier soils and in morphology by possessing smaller flowers and fewer leaves.
|
|
Only one other species so far, S. merjamie, has been conclusively shown to have a chromosome count of 2n=42. S. sclarea, on the other hand, has a count of 2n=22 chromosomes. Further comparison between S. tingitana and possible related species was done using mucilage testing. Those tests also indicated S. tingitana to be a unique species.

Droseraceae are carnivorous herbaceous plants that may be annuals or perennials. Their leaves are alternate and adaxially circinate, with at least one leaf surface containing hairs with mucilage- producing glands at the tip. Their flowers are bisexual, usually with three carpels and five sepals, petals and stamens. Their pollen grains are triporate or multiporate and released in tetrads.
|
|
The relationships between the "core Malvales" families used to be defined on the basis of shared "malvean affinities". These included the presence of malvoid teeth, stems with mucilage canals, and stratified wedge-shaped phloem. These affinities were problematic because they were not always shared within the core families. Later studies revealed more unambiguous synapomorphies within Malvaceae s.

The leaves are rich in the nutrients carotene, vitamin A, ascorbic acid, calcium, and iron. The seeds are composed of "protein, starch, sugar, mucilage, minerals, volatile oil, fixed oil, vitamins and enzymes". They smell of curry but are quite bitter and contain coumarin oil. The seeds also contain diosgenin which is used in the manufacture of oral contraceptives.
|
|
The spores are covered with a sheath of mucilage, which typically causes the eight spores of the ascus to be ejected together. The paraphyses (sterile filamentous hyphal end cells in the hymenium) are slender, slightly enlarged above, and contain numerous red granules. The granules contain carotenoid pigments such as plectaniaxanthine or beta carotene, and give the fruit body its color.

Association of K. oxytoca with the barley rhizosphere during an entire vegetative period has been demonstrated. The bacteria adhere strongly to root hairs, and less strongly to the surface of the zone of elongation and root cap mucilage. Like other enterobacteria, it is capable of acquiring antibiotic resistance, and isolates have been shown to produce extended-spectrum beta-lactamases as well as carbapenemases.

Members of Dictyochloropsis are free-living, unicellular green algae. Their cells lack flagella and are globular at all life cycle stages. In this genus, young cells from autospores can be as small as 6 μm in diameter, and the largest species grow up to 50 μm in diameter before reproducing. The cell is often surrounded by a thick envelope of mucilage when mature.
|
|
As the invertebrates feed on the mucilage, excess pollen grains stick to their bodies. They move from flower to flower, feeding and spreading the pollen from male to female. Seeds begin to develop in about 2–4 weeks if fertilization occurred. Female turtle grass fruits develop into green capsule about 20–25 mm in diameter and can include 1-6 small seeds.

Saccharina dentigera is a large brown seaweed growing to a length of . The thallus is dark brown, thick and leathery, often appearing palmate because of being split into broad lobes to within of its base. Younger thalli are entire with ovate blades. The thallus is supported on a robust, semi-rigid stipe, which has mucilage ducts on its surface near the upper end.

The outer cells of the whole trap excrete mucilage and under the door this is produced in greater quantities and contains sugars. The mucilage certainly contributes towards the seal, and the sugars may help to attract prey. Terrestrial species, like U. Sandersonii have tiny traps (sometimes as small as 0.2 mm) with a broad beak-like structure extending and curving down over the entrance; this forms a passageway to the trapdoor and may help prevent the trapping and ingestion of inorganic particles. Aquatic species, like U. inflata tend to have larger bladders (up to 1.2 cm), and the mouth of the trap is usually surrounded not by a beak but by branching antennae, which serve both to guide prey animals to the trap's entrance and to fend the trap mouth away from larger bodies which might trigger the mechanism needlessly.

The style is a narrow upward extension of the ovary, connecting it to the stigmatic papillae. It may be absent in some plants in the case the stigma is referred to as sessile. Styles are generally tube-like—either long or short. The style can be open (containing few or no cells in the central portion) with a central canal which may be filled with mucilage.

Cape sundew In botany, tentacles are glandular hairs on the leaves of some species of insectivorous plants such as Drosera (sundews). Tentacles are different from organs such as the tendrils of climbing plants. In carnivorous plants such as sundews, the tentacles are the stalked glands of the upper surface of the leaves. They are hairlike projections with a drop of sticky mucilage which attract insects.

Most of the production is grown under shade trees and wet processed at farm level. Coffee from Flores is known for sweet chocolate, floral and woody notes. A traditional style of processing, known as pulped natural, where parchment coffee is dried in its mucilage without fermentation, produces a floral coffee that has been found to be highly sought after by some buyers.Marsh, A., Yusianto, Mawardi, S. (2010).
|
|
The mature coffee fruit, referred to as the coffee cherry, is harvested. and farmers remove the outer skin mechanically using locally built pulping machines. The coffee beans, coated with mucilage, are stored for up to a day during which a natural fermentation breaks down the sticky residue. Afterwards the coffee beans, protected by a parchment hull (endocarp) are washed off before being let out to dry.
|
|
Pinguicula primuliflora, like all members of the family Lentibulariaceae, is carnivorous. Their leaves are covered with tiny hairs which secrete a mucilaginous liquid. This gives the leaves a wet appearance and is believed to attract insects in search of water. As soon as an insect lands on the leaves, it becomes ensnared in the mucilage; as it struggles, it gathers more of the liquid on it.
|
|
However, wet processing is believed to yield higher quality coffee than the other processes since small amounts of off-flavors give the coffee its particular taste and "body". When fermentation is complete, the beans are washed thoroughly to remove fermentation residues and any remaining mucilage. If not removed, these cause decolouring of the parchment and make the beans susceptible to yeasts. After washing, the beans are dried.

Besides its ornamental value the species' leaves and bark are used in decoctions and infusions for a variety of ailments and conditions - the seed-coat mucilage as a pain-killer, the bark and leaves against pulmonary problems, stomach ailments, roots to combat cutaneous and subcutaneous parasitic infections, and the bark for aphrodisiacs and febrifuges. The stems produce tough fibres used as general purpose binding material.

Proterospongia species are distinguished by colony morphology, which vary from simple chains of cells to striking astral assemblages.Kent, W.S. Manual of the Infusoria (1880-1882) Colonies having extra cellular jelly or mucilage have been described by Kent, Lackey, and Leadbeater; however the composition of this substance is unknown.Lackey, J.B. Morphology and Biology of a Species of Proterospongia. Trans. Amer. Micro. Soc. (1959) pp. 202-206.

There are two methods of pollination: hydrophily and biotic pollination. In hydrophilic pollination, the pollen grains are carried through the water column by tides or currents and deposited upon an open pistillate flower. Underwater video cameras have more recently revealed crustaceans, polychaetes, and amphipods swimming towards open male flowers. These creatures were attracted to the seagrass’s nutritious mucilage—a carbohydrate-rich substance that houses pollen.
|
|
These cells produce a mucilaginous secretion which forms visible droplets across the leaf surface. This wet appearance probably helps lure prey in search of water; a similar phenomenon is observed in the sundews. The droplets secrete only limited enzymes and serve mainly to entrap insects. On contact with an insect, the peduncular glands release additional mucilage from special reservoir cells located at the base of their stalks.
|
|
Some contend that their function is to aid in pollination, adhering seeds to visiting pollinators.Fahn and Werker, 1972 Others note that on some species (Plumbago auriculata), small, crawling insects have been trapped in the Plumbago's mucilage, which supports the conclusion that these tentacles could have evolved to exclude crawling insects and favor flying pollinators for greater seed dispersal or perhaps for protection against crawling insect predators.

|
The main characteristics that determine the choice of farmers for cultivars are sweetness, storage capacity before consumption, mucilage content and yield. Skin color is also a key parameter to consider while assessing the potential of the ulluco culture. Red tuber plants are the most frost-resistant and yellow tubers are the most popularly eaten in markets in Ecuador. The attractiveness of the color of cultivars varies among countries and regions.

Another plant-derived mucilage is made from sodium alginate. In recent years, a synthetic size made from hydroxypropyl methylcellulose, a common ingredient in instant wallpaper paste, is often used as a size for floating acrylic and oil paints. In the size-based method, colors made from pigments are mixed with a surfactant such as ox gall. Sometimes, oil or turpentine may be added to a color, to achieve special effects.

Two methods are primarily used to process coffee berries. The first, "wet" or "washed" process, has historically usually been carried out in Central America and areas of Africa. The flesh of the cherries is separated from the seeds and then the seeds are fermented – soaked in water for about two days. This softens the mucilage, which is a sticky pulp residue that is still attached to the seeds.
|
|
Then this mucilage is washed off with water. The "dry processing" method, cheaper and simpler, was historically used for lower-quality beans in Brazil and much of Africa, but now brings a premium when done well. Twigs and other foreign objects are separated from the berries and the fruit is then spread out in the sun on concrete, bricks or raised beds for 2–3 weeks, turned regularly for even drying.
|
|
Coffee cherry cross-section The term "green coffee bean" refers to unroasted mature or immature coffee beans. These have been processed by wet or dry methods to remove the outer pulp and mucilage and have an intact wax layer on the outer surface. When immature, they are green. When mature, they have a brown to yellow or reddish color and typically weigh 300 to 330 mg per dried coffee bean.
|
|
Vincent, J.-C. in , p. 1. Then they are sorted by ripeness and color, and most often the flesh of the berry is removed, usually by machine, and the seeds are fermented to remove the slimy layer of mucilage still present on the seed. When the fermentation is finished, the seeds are washed with large quantities of fresh water to remove the fermentation residue, which generates massive amounts of coffee wastewater.

|
Addison-Wesley Publishing Company. Ecologically sensitive farms reprocess the wastewater along with the shell and mucilage as compost to be used in soil fertilization programs. The amount of water used in processing can vary, but most often is used in a 1 to 1 ratio. After the pulp has been removed what is left is the bean surrounded by two additional layers, the silver skin and the parchment.

The number of nuclear divisions prior to cell division dictates the number of spores which will be produced, this can vary even between individuals in the same species. Next, autospores are produced inside the mother cell’s mucilage forming an autosporangium. When the spores are formed, the autosporangium decays by rupturing or dissolving, depending on the species. As Dictyochloropsis cells prepare to divide, several intracellular changes happen to the chloroplast.

The connective tissue between the lobes of the anther extends upward for 0.6-0.7 millimeters to form a tapering tip. Its flowers have 50-100 carpels with oblong, flattened ovaries that are 2-2.2 millimeters long and covered in dense, matted, silky, golden hairs. Each ovary has 1-2 ovules. Its flattened styles are 4.5-5 millimeters long and come to a tapering tip that exudes sticky mucilage.

|
This cell wall is used to produce everyday products such as timber, paper, and natural fabrics, including cotton. Root mucilage is a part of a wider secrete from plant roots known as root exudate. Plant roots secrete a variety of organic molecules into the surrounding soil, such as proteins, enzymes, DNA, sugars and amino acids, which are the building blocks of life. This collective secretion is known as root exudate.
|
|
The ascospores may be arranged in one or two rows (uniseriate and biseriate, respectively), or rarely, irregular. The ascospores are ellipsoid, translucent, have a slight curve and may be tapered; most ascospores contain two oil drops. When in the ascus, the ascospores are covered with a translucent mucilage that is highly refractive to light. Paraphyses are filamentous hyphal cells present in the fertile spore-bearing tissue, distributed amongst the asci.

If the cap is carefully removed the root will grow randomly. The root cap protects the growing tip in plants. It secretes mucilage to ease the movement of the root through soil, and may also be involved in communication with the soil microbiota. The purpose of the root cap is to enable downward growth of the root, with the root cap covering the sensitive tissue in the root.

0235560100 Cells at this stage are most resistant to harsh environmental conditions. Inorganic and organic materials such as bacteria, fungi, and dust particles coat the mucilage layer of the cell wall. The inorganic impurities were found to be rich in silicon, iron, and aluminum. These elements can also be taken up into the cellular compartment and stored in vacuoles and may be an importance source of mineral supply.

In 1972, the American phycologist James W. Markham did some transplanting experiments to try to determine whether the presence of mucilage glands is a distinctive feature or the two species were identical. He found that they were indeed distinct and that there were some other differences between the two related to the width of blades, the shedding of the blades, the morphology of the reproductive structures, temperature tolerance and habitat preference.

The insect struggles, triggering more glands and encasing itself in mucilage. The sessile glands, which lie flat on the leaf surface, serve to digest the insect prey. Once the prey is entrapped by the peduncular glands and digestion begins, the initial flow of nitrogen triggers enzyme release by the sessile glands. These enzymes, which include amylase, esterase, phosphatase, protease, and ribonuclease break down the digestible components of the insect body.

|
These colors are due to the accumulation of ferric hydroxide and manganic oxide deposited with the mucilage and minerals that comprise the lorica. In Trachelomonas, the presence of a lorica obscures cytoplasmic details of the underlying cell. In each Trachelomonas cell, there is a gap at the apex of the lorica from which the flagellum protrudes. Thickening around this gap results in a rim-like or collar-like appearance.

S. fimbriatum displaying the trichomes that can trap and kill insects. Stylidium species with glandular trichomes on their sepals, leaves, flower parts, or scapes have been suggested to be protocarnivorous (or paracarnivorous). The tip of the trichome produces a sticky mucilage—a mixture of sugar polymers and water—that is capable of attracting and suffocating small insects. The ability to trap insects may be a defensive mechanism against damage to flower parts.

Gloeotrichia is a large (~2 mm) colonial genus of Cyanobacteria, belonging to the order Nostocales. The name Gloeotrichia is derived from its appearance of filamentous body with mucilage matrix. Found in lakes across the globe, gloeotrichia are notable for the important roles that they play in the nitrogen and phosphorus cycles. Gloeotrichia are also a species of concern for lake managers, as they have been shown to push lakes towards eutrophication and produce deadly toxins .

The Nymphaeaceae are aquatic, rhizomatous herbs. The family is further characterized by scattered vascular bundles in the stems, and frequent presence of latex, usually with distinct, stellate- branched sclereids projecting into the air canals. Hairs are simple, usually producing mucilage (slime). Leaves are alternate and spiral, opposite or occasionally whorled, simple, peltate or nearly so, entire to toothed or dissected, short to long petiolate), with blade submerged, floating or emergent, with palmate to pinnate venation.

Kerosene can be applied topically to hard-to-remove mucilage or adhesive left by stickers on a glass surface (such as in show windows of stores).Kerosene: Other uses: Miscellaneous. Oilfielddirectory.com. Retrieved on 2 June 2015. It can be used to remove candle wax that has dripped onto a glass surface; it is recommended that the excess wax be scraped off prior to applying kerosene via a soaked cloth or tissue paper.

An Indian craftsman applying the syahi (Hyderabad, Sind - circa 1977) The application of the syahi is very involved. It starts with a base layer of mucilage, followed by the application of numerous thin layers of syahi masala (flour, water, iron filings and other secret ingredients), which are then rubbed with a stone. Not all of the layers are the same size. But the final product is expected to exhibit a specific shape.

These internodes provide a nesting area for the Azteca ants that inhabit the trees. When the branches are cut, they release a watery, often mucilaginous sap, which turns black when it is exposed to the air. To prevent inhabitation by ants and occupation and damage by herbivorous insect larvae, the terminal buds and upper internodes are filled with mucilage. Several species’ leafy twigs are covered by a waxy layer, making them bluish.

Pinguicula longifolia, commonly known as the long-leaved butterwort, is a perennial carnivorous subalpine plant of the Central Pyrenees, found on both sides of the border. It catches its prey by using its modified leaves that lie on the ground and have “densely covered stalked glands that bear a droplet of sticky mucilage on its top.” The need to capture arthropods is driven by the lack of nutrients present in the soil. P. l. subsp.

The tentacles of all Drosera species have special stalked glands on the leaf's upper surface that produce a sticky mucilage. The leaves are considered active flypaper traps that respond to captured prey by bending to surround it. In its native fynbos habitat, the plants compete for space with native marsh grasses and low evergreen shrubs. Of the two known populations of D. regia, the higher altitude site appears to be overgrown and is essentially extirpated.

Starch is the main component of the dried peeled roots with 54.5–62.4% (differs according to the climatic region of cultivation) while protein represents 4.5–8.3%, half of which is aspartic acid. Roots contain high amounts of non-starch polysaccharides including dietary fibers, pectin and up to 27% of mucilage. Calcium, magnesium and iron are the main minerals of the roots. Minor amounts of zinc, manganese and copper have also been found.

The wood from C. sulcata is used for barrels and boxes since it is a soft/lightweight type of wood. It is also normally used for fuel, charcoal, and poles. From the fruit of the tree, the mucilage (viscous solution that is extracted from the fruit) is used for glue and maintaining dreadlocks. Parts of the tree have been used in the past for folk medicine, such as treating bronchitis and as a diuretic.

Pandorina is a genus of green algae composed of 8, 16, or sometimes 32 cells, held together at their bases to form a sack globular colony surrounded by mucilage. The cells are ovoid or slightly narrowed at one end to appear keystone- or pear-shaped. Each cell has two flagella with two contractile vacuoles at their base, an eyespot, and a large cup-shaped chloroplast with at least one pyrenoid. Pandorina sp.

The female chews a hole in a closed flower head, deposits an egg inside, and seals the hole with a dark-colored mucilage. This visible hole can warp the shape of the flower head as it grows. The larva emerges from its egg in about three days and begins to feed on the flower parts and developing seeds. In just over two weeks the larva can destroy all or nearly all of the developing seeds.

It is an annual erect herb, reaching heights of 50 to 150 cm. It has heteromorphic leaves deeply divided into narrow, linear-lanceolate lobes; the upper leaves are simple, with the exception of some mucilage glands with an entire margin.Kirby, G. (2013). Wild Flowers of Southeast Botswana Struik Nature, Cape Town South Africa Page 289 Its flowers measure 3.5 cm in diameter and are reddish pink with darker lines in the lower lobe of the corolla.

In Egypt, the leaves are made into a stew-like vegetable dish, especially in winter, known as khobeiza, which is similar to Molokheia. In traditional medicine, M. sylvestris has been used in herbalism. Mucilage is present in many of the family Malvaceae including M. sylvestris, especially the fruit. The seeds are used internally in a decoction or herbal tea as a demulcent, and the leaves may be used in poultices as an emollient for external applications.

Terns may be killed or injured by collisions with trawl warps, trapped in trawls or discarded gear, or hooked by longline fishing, but, unlike albatrosses and petrels, there is little evidence that overall numbers are significantly affected. An unusual incident was the incapacitation of 103 terns off Robben Island, South Africa by marine foam, generated by a combination of wave action, kelp mucilage and phytoplankton. After treatment, 90% of the birds were fit to be released.

This process is mainly used when processing Coffea arabica. After de-pulping, the beans are collected in fermentation tanks where bacterial removal of the mucilage takes place over 12 to 36 hours. The fermentation phase is important in the development of the flavour of the coffee, which is partially due to the microbiological processes that take place. The emergence of yeasts and moulds in acidic water can lead to off-flavors like sour coffee and onion-flavour.
|
|
The first step in dry milling is the removal of what is left of the fruit from the bean, whether it is the crumbly parchment skin of wet-processed coffee, the parchment skin and dried mucilage of semi-dry- processed coffee, or the entire dry, leathery fruit covering of the dry- processed coffee. Hulling is done with the help of machines, which can range from simple millstones to sophisticated machines that gently whack at the coffee.

Ceratotheca sesamoides is a plant with many uses and applications. When cooked directly in soups the mucilage containing leaves help to minimize nutrient loss. Leaves are finely chopped and can be used in a variety of different sauces, a common example being a mixture of chopped leaves, groundnut flour, salt, onions, tomatoes and a small amount of hot water often eaten with porridge. Ash is often used to lessen the impact of the bitter taste of the leaves.

Folk medicine names for comfrey include knitbone, boneset, and the derivation of its Latin name Symphytum (from the Greek symphis, meaning growing together of bones, and phyton, a plant), referring to its ancient uses. Similarly, the common French name is consoude, meaning to weld together. The tradition in different cultures and languages suggest a common belief in its usefulness for mending bones. Comfrey contains mixed phytochemicals in varying amounts, including allantoin, mucilage, saponins, tannins, pyrrolizidine alkaloids, inulin, and proteins, among others.

When the fermentation is complete, the coffee is thoroughly washed with clean water in tanks or in special washing machines. In machine-assisted wet processing, fermentation is not used to separate the bean from the remainder of the pulp; rather, this is done through mechanical scrubbing. This process can cut down on water use and pollution since ferment and wash water stinks. In addition, removing mucilage by machine is easier and more predictable than removing it by fermenting and washing.

Orchids in the genus Microtis are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and an egg-shaped to almost spherical tuber. The tuber often produces two tubers on the end of long, root- like stolons. There is a single, linear, cylindrical, onion-like leaf at the base of the plant. The leaf resembles that of the closely related genus Prasophyllum except that is entirely green (usually red at the base in Prasophyllum) and exudes clear mucilage when damaged.

As roots penetrate through the soil, many of the cells surrounding the caps of roots are continually shed and replaced. These ruptured or lysed cells release their component parts, which include the polysaccharides that form root mucilage. These polysaccharides come from the Golgi apparatus and plant cell wall, which are rich in plant- specific polysaccharides. Unlike animal cells, plant cells have a cell wall that acts as a barrier surrounding the cell providing strength, which supports plants just like a skeleton.

The so-called moghatin is a biflavone that has been uniquely discovered in moghat. Seeds contain around 19.5% protein, 5.0% mucilage, arabinose (1.8%) and glucuronic acid (14.6%). Both roots and seeds contain rhamnose, xylose, mannose and galacturonic acid.

Insects and other prey animals are attracted by the smell of this mucilage and become stuck in it. Such snares are termed “flypaper traps”, but the trapping mechanism of sundews is often erroneously described as “passive”. In fact, sundew traps are quite active and sensitive, and the disturbance of one or a few trichomes quickly triggers an action potential that stimulates the rapid movement of other trichomes toward the prey. The leaf then curls in on itself, enveloping the prey for digestion.

The seed is propagated through the onset of rains. Like other members of the plant family Pedaliaceae, false sesame is covered in mucilage glands which can enable the plant to survive dehydration without tissue death, making the plant drought resistant. False sesame is very flexible with regards to environment and growing conditions occurring as a weed and in cultivated fields, growing best in well-drained sandy soils with high exposure to the sun but with less success in rocky areas.

The attachment of a fungal spore on the surface of the host plant is the first critical step of infection. Once the spore is hydrated, an adhesive mucilage is released from its tip. During germination, mucilaginous substances continue to be extruded at the tips of the germ tube, which are essential for germ tube attachment and appressorium formation. Spore adhesion and appressorium formation is inhibited by hydrolytic enzymes such as α-mannosidase, α-glucosidase, and protease, suggesting that the adhesive materials are composed of glycoproteins.

Microcystis floating colonies in an Erlenmeyer flask. As the etymological derivation implies, Microcystis is characterized by small cells (a few micrometers in diameter), possessing gas filled vesicles (also lacking individual sheaths). The cells are usually organized into colonies (macroscopic aggregations of which are visible with the naked eye) that begin in a spherical shape, losing coherence to become perforated or irregularly shaped over time. These colonies are bound by a thick mucilage composed of complex polysaccharide compounds, including xylose, mannose, glucose, fucose, galactose, rhamnose, among other compounds.

Many protists and bacteria produce other cell surface structures apart from cell walls, external (extracellular matrix) or internal. Many algae have a sheath or envelope of mucilage outside the cell made of exopolysaccharides. Diatoms build a frustule from silica extracted from the surrounding water; radiolarians, foraminiferans, testate amoebae and silicoflagellates also produce a skeleton from minerals, called test in some groups. Many green algae, such as Halimeda and the Dasycladales, and some red algae, the Corallinales, encase their cells in a secreted skeleton of calcium carbonate.

Suillus lakei forms ectomycorrhizae with Douglas fir (Pseudotsuga menziesii), and its distribution coincides with this tree. It is one of the most common bolete species found in northwestern Montana and Idaho. In a study of host specificity in pure culture in the laboratory, S. lakei failed to form healthy ectomycorrhizas with Eucalyptus roots—the hyphae were covered in mucilage-like deposits and appeared to be collapsed. It has also been noted to prefer poor, exposed soil such as that found on road banks and campgrounds.

In plant systems, Klebsiella can be found in a variety of plant hosts. K. pneumoniae and K. oxytoca are able to fix atmospheric nitrogen into a form that can be used by plants, thus are called associative nitrogen fixers or diazotrophs. The bacteria attach strongly to root hairs and less strongly to the surface of the zone of elongation and the root cap mucilage. They are bacteria of interest in an agricultural context, due to their ability to increase crop yields under agricultural conditions.

The stipe lengthens, orients upward, and two types of hyphal elements develop: long, straight and smooth basal hairy hyphae and short stipe hyphae, some of which are inflated and project out of a cohesive layer of tightly packed hyphal elements. In the final stage, which occurs when the stipe is long, immature caps appear that have ridges and pits with distinct filament-like paraphyses. Extracellular mucilage that covers the ridge layer imparts shape and rigidity to the tissue and probably protects it against dehydration.

Drosera uniflora is a species in the carnivorous plant genus Drosera that is native to southern Chile, Argentina, and the Falkland Islands. It is a tiny sundew with a solitary white flower as its name would suggest. Stalked glands on its leaves, which secrete sticky mucilage at the tips, are used to capture and hold insect prey, from which the plant derives the nutrients it cannot obtain in sufficient quantity from the soil. It was formally described in 1809 by botanist Carl Ludwig Willdenow.

P. washingtonensis has scattered to abundant pleurocystidia (cystidia on the gill face) that typically measure 38–56 by 9–12 μm. There are two forms of cheilocystidia (cystidia in the gill edge): one is fusoid- ventricose (distinctly enlarged in the middle and tapered toward both ends) with blunt to somewhat sharp apices, often covered with mucilage, and measures 26–38 by 7–11 μm; the other is broadly club-shaped to capitate (with a distinct spherical tip), and measures 26 by 10–12 μm.

Roridula dentata is a protocarnivorous plant native to the Western Cape province of South Africa. It can be found only in South Africa, in the hotter and more arid inland mountains of Clanwilliam, Tulbagh and Ceres, and can grow up to more than 150 cm. The leaves are covered with sticky hairs and produce a resin (rather than a mucilage as in most other sticky carnivorous plants), enabling it to catch insects, such as wasps or bees, and very occasionally small birds.McPherson, Stewart. 2008.

Psyllium is mainly used as a viscous, soluble dietary fiber that is not absorbed by the small intestine. The purely mechanical action of psyllium mucilage is to absorb excess water while stimulating normal bowel elimination. Although its main use has been as a laxative, it is more accurately regarded as a dietary fiber and as such can help reduce the symptoms of both constipation and mild diarrhea. The laxative properties of psyllium are attributed to the fiber: it absorbs water and subsequently softens the stool.

Small insects often get trap by the glandular stalks for mistaking the mucilage as water drops.Botanical Society of America, the Butterworts, April 28,2012 Once the prey stuck on the droplets, a digestive enzyme is released to extract nitrogen from the insect. The margin of the leaves also slowly roll inward and relax again after the digestion is complete. Like many carnivorous plants, this trapping mechanism allows the plant to seek supplement nitrogen sources from the insect as a way to replace the nutrient-deficient habitat.

Coccomyxa is a genus of green algae, in the family Coccomyxaceae. This genus is defined by their small, elliptical to spherical shape, and the presence of a simple parietal chloroplast. These features, along with their occurrence in various lifestyles such as free-living, parasitic, or as photobionts, have been used to identify over 40 species. Using additional morphological features, such as brown akinetes formation, allows for the differentiation between Coccomyxa and the genus Pseudococcomyxa, as they tend to share some morphological characteristics like the general cell shape and one-sided mucilage cap.

The heads of the archegonia have a mucilage which attracts the sperm, and the degeneration of the neck canal allows for the passage of sperm to the egg, resulting in fertilization. The fertilized egg develops into a sporophyte, which is diploid, and protected by a remnant of the archegonium now known as the calyptra. Inside the developing sporangium, haploid spores are generated via meiosis. The seta raises the sporangium into the air, and once the sporangium is mature, the operculum falls off and the spores are released into the wind.
|
|
This sinking is induced by either a loss of buoyancy control, the synthesis of mucilage that sticks diatoms cells together, or the production of heavy resting spores. Sinking out of the upper mixed layer removes diatoms from conditions unfavourable to growth, including grazer populations and higher temperatures (which would otherwise increase cell metabolism). Cells reaching deeper water or the shallow seafloor can then rest until conditions become more favourable again. In the open ocean, many sinking cells are lost to the deep, but refuge populations can persist near the thermocline.

Washing of the fermented beans leads to wastewater containing mainly pectins from the mucilage, proteins and sugars. The fermentation of the sugars (disaccharide carbohydrates) into ethanol and CO2 leads to acid conditions in the washing water. The ethanol is converted in acetic acids after reaction with oxygen, lowering the pH to levels of around 4. The high acidity can negatively affect the treatment efficiency of treatment facilities treating the coffee wastewater like an anaerobic reactor or constructed wetlands and is considered to be detrimental for aquatic life when discharged directly into surface waters.

This network of fungi hyphae can shuttle water and nutrients from one part of the forest to another when needed. It can also shuttle carbohydrates throughout the network so that the network is not disrupted by a lack of carbohydrate input. Root mucilage also helps soil to stick to roots. The purpose of this is to maintain the plant's contact with the soil so that the plant can regulate the levels of water it can absorb, decrease friction so that roots can penetrate through the soil, and maintain a micro-climate.

The silica frustules also contribute vastly to the sediment layers of the earth and to the fossil record, which makes them exceptionally useful in increasing understanding of numerous processes such as gauging the degree of climate change. Before sinking to the ocean floor, every atom of silicon that enters the ocean is integrated into the cell wall of a diatom about 40 times. Silica frustules contain a central raphe, which secretes mucilage that allows the cells to move by gliding. Cells are often found in overlapped, stepped colonies, and exhibit collective motility.

The leaf shape depends on the species, but is usually roughly obovate, spatulate, or linear. They can also appear yellow in color with a soft feel and a greasy consistency to the leaves.` Vector graphic of the trapping and digestive features of a Pinguicula leaf Like all members of the family Lentibulariaceae, butterworts are carnivorous. The mechanistic actions that these plants use to lure and capture prey is through a means of sticky or adhesives substances that are produced by mucilage separated by glands located on the leaf’s surface.

The elephant literally dumps into "Poppy" and company among the bubblegum and mucilage geysers (or "gozzers") of Gozzerland National Park. The four travelers combine, for further adventures in Cleanitupia and Pristinia. It is only when Kabumpo sees "Poppy" with her long hair unconfined that he recognizes Ozma; then he needs to win the trust of the suspicious amnesiac and bring her home to the Emerald City. (He fails completely at the winning of trust, and hauls her back bodily.) Eventually, Ozma uses the Magic Belt to restore her memory and return to normal.

The plant may be used as an ingredient in adobe to bind and waterproof roofs. O. ficus-indica (as well as other species in Opuntia and Nopalea) is cultivated in nopalries to serve as a host plant for cochineal insects, which produce desirable red and purple dyes, a practice dating to the pre-Columbian era. Mucilage from prickly pear may work as a natural, non-toxic dispersant for oil spills. In Mexico there is a semi- commercial pilot plant for biofuel production from opuntia biomass, in operation since 2016.

The female lays up to 470 eggs near the flower heads of yellow starthistle and glues them with a dark-colored mucilage. When the larva emerges from its egg, it tunnels up into the flower head, where it consumes the flower parts and developing seeds. It then constructs a sort of cocoon from the remnants of the flower and seed parts and pupates there. Most of the damage to the plant is done by the larva, which destroys 50-60% of the seeds in a given flower head.

The plant grows as a small rosette of leaves, which rarely get larger than 3/4 of an inch (20mm) across. The leaves have inward curling margins, and the upper surface is covered in numerous tiny hairs with glands at their tip which secrete small drops of mucilage. The plant produces single white to pale violet flowers on the ends of stalks about 6-8 inches (150-200 mm) high. Like all butterworts, the flowers are zygomorphic, and have a spur extending from the back of the flower.

7 (1991) by F.E. Round (Volume editor), David J. Chapman (Volume editor) The frustule's structure is usually composed of two overlapping sections known as thecae (or less formally as valves). The joint between the two thecae is supported by bands of silica (girdle bands) that hold them together. This overlapping allows for some internal expansion room and is essential during the reproduction process. The frustule also contains many pores and slits that provide the diatom access to the external environment for processes such as waste removal and mucilage secretion.

In December 2014, vegan musician Joël Roessel found that water from canned beans can form foams much like protein isolates and flax mucilage do. Roessel shared his experiments on a blog and published recipes for floating island of Chaville, chocolate mousse, and meringue made from chickpea liquid to demonstrate its foaming capabilities. Around the same time, vegan food enthusiast Goose Wohlt discovered that the cooking liquid can replace egg white without the need for stabilizers. In March 2015 he published a recipe for egg-free meringue using only chickpea liquid and sugar.

Flowers appear on pineapple grass in summer on structures called racemes. The plant is dioecious, meaning it has separate male and female flowers. Like other species of Astelia, which grow in areas that are moist and humid, the ovary is full of mucilage, which is thought to function in pollen transmittance.Kocyan, A. and Endress, P.K. (2001) "Floral structure and development and systematic aspects of some 'lower' Asparagales" Plant Systematics and Evolution 229(3-4): 187-216 Humans can facilitate asexual reproduction by breaking apart mature clumps and planting them separately.

Compared to oilseed meal from crucifers it measures as having lower nutrient values, however, good results are obtained in cattle, perhaps due to the mucilage, which may aid in slowing digestion and thus allowing more time to absorb nutrients. One study found that feeding flax seeds may increase omega-3 content in beef, while another found no differences. It might also act as a substitute to tallow in increasing marbling. In the US, flax-based feed for ruminants is often somewhat more expensive than other feeds on a nutrient basis.

It is widely assumed pitfall traps evolved by epiascidiation (infolding of the leaf with the adaxial or upper surface becoming the inside of the pitcher), with selection pressure favouring more deeply cupped leaves over evolutionary time. The pitcher trap evolved independently in three eudicot lineages and one monocot lineage, representing a case of convergent evolution. Some pitcher plant families (such as Nepenthaceae) are placed within clades consisting mostly of flypaper traps, indicating that some pitchers may have evolved from the common ancestors of today's flypaper traps by loss of mucilage.

Artists like Robert Rauschenberg and Jasper Johns started using scrappy materials and objects to make anti-aesthetic art sculptures, a big part of the ideas that make assemblage what it is. The painter Armando Reverón is one of the first to use this technique when using disposable materials such as bamboo, wires, or kraft paper. In the thirties he made a skeleton with wings of mucilage, adopting this style years before other artists. Later, Reverón made instruments and set pieces such as a telephone, a sofa, a sewing machine, a piano and even music books with their scores.

It is unique in the subgenus because of its large leaves that are typically flat against the soil. Retentive mucilage-producing glands held on stalks – structures known as tentacles – appear on the margin of the lamina with shorter glands in the center of the leaf. The abaxial (underside) surface of the leaf is noticeably veined and sparsely covered with non-glandular white hairs. Petioles are oblanceolate and usually 10 mm long with varying widths: 2 mm near the center of the rosette, 3.5 mm near the center of the petiole, and 3 mm at the point of attachment to the lamina.

Detail of a leaf A leaf wrapped around prey Detail of a flower Drosera regia plants are fairly large herbs that produce horizontal woody rhizomes and a crown of large, linear leaves up to long and wide. The leaves possess stalked glands (tentacles) on the upper surface of the lamina along nearly the entire length of the leaf. The leaves lack petioles and stipules, emerging by circinate vernation (uncurling) and tapering to a filiform point. The tentacles and the leaf itself are capable of responding to prey by bending toward insects trapped in the sticky mucilage produced by the glands.

In addition to seed propagation, new plants are formed from the tips of existing canes touching the ground. They enjoy moist soil and grow near and within wooded areas. Unripe berries covered by glandular hairs As a fruit develops, it is surrounded by a protective calyx covered in hairs that exude tiny drops of sticky fluid. While the structure resembles those of carnivorous plants, the wineberry plant does not get nutrients from insects caught in the sap: the sticky mucilage contains no digestive enzymes, surrounding tissues cannot absorb nutrients, and there are no protein-storage tissues.

Banksia incana resprouts from its woody lignotuber after bushfire. Banksia incana is one of five closely related Banksia species that have highly unusual flower nectar. Whereas other Banksia species produce nectar that is clear and watery, the nectar of these species is pale yellow initially, but gradually becomes darker and thicker, changing to a thick, olive-green mucilage within one to two days of secretion, and eventually becoming "an almost black, gelatinous lump adhering to the base of the flowers". It was first noted by Byron Lamont in 1980; he attributed it to cyanobacteria that feed off the nectar sugars.

No pollinators of this species were recorded in The Banksia Atlas survey. Banksia grossa is one of five closely related Banksia species that have highly unusual flower nectar. Whereas other Banksia species produce nectar that is clear and watery, the nectar of these species is pale yellow initially, but gradually becomes darker and thicker, changing to a thick, olive-green mucilage within one to two days of secretion, and eventually becoming "an almost black, gelatinous lump adhering to the base of the flowers". It was first noted by Byron Lamont in 1980; he attributed it to cyanobacteria that feed off the nectar sugars.

A study found that after consumption of fruit the concentration of methanol in the human body increased by as much as an order of magnitude due to the degradation of natural pectin (which is esterified with methyl alcohol) in the colon. Pectin has been observed to have some function in repairing the DNA of some types of plant seeds, usually desert plants. Pectinaceous surface pellicles, which are rich in pectin, create a mucilage layer that holds in dew that helps the cell repair its DNA. Consumption of pectin has been shown to slightly (3-7%) reduce blood LDL cholesterol levels.

The family consists of Géza, the father, a comical and inept figure similar to Homer Simpson, his wife Paula who actually dominates family affairs, pubertal daughter Kriszta and 12-14-year-old son Aladár (12 in first series, 14 in the last, the medium age is 13), a child prodigy. The cat Maffia and a dog, Blöki (Zorro) accompany the family. Dr. Máris, their cynical neighbour, is regularly and unvoluntarily involved in disasters surrounding the family. The name "Mézga" means glue, mucilage or tree gum in Hungarian and was renamed as rodina Smolíkova in Czech, which is a surname (derived from "smůla", i.e.

As with all Drosera, this plant feeds on insects, which are attracted to the bright red colour and the glistening drops of mucilage, loaded with a sugary substance, covering its leaves. It has evolved this carnivorous activity in response to its habitat, which is usually poor in nutrients or is so acidic that nutrient availability is severely diminished. The plant uses enzymes to dissolve the insects – which become stuck to the glandular trichomes – and extract ammonia (from proteins) and other nutrients from their bodies. The ammonia replaces the nitrogen that most plants absorb through their roots.

A ripe bael fruit, India Bael fruit The bael fruit typically has a diameter of between 5 and 12 cm. It is globose or slightly pear-shaped with a thick, hard rind and does not split upon ripening. The woody shell is smooth and green, gray until it is fully ripe when it turns yellow. Inside are 8 to 15 or 20 sections filled with aromatic orange pulp, each section with 6 (8) to 10 (15) flattened-oblong seeds each about 1 cm long, bearing woolly hairs and each enclosed in a sac of adhesive, transparent mucilage that solidifies on drying.

Since Z. floridana is a cycad, which are the only group of gymnosperms that form nitrogen-fixing associations, it depends on microbes as a source of nitrogen. It forms a symbiotic relationship with nitrogen-fixing cyanobacteria, which live in specialized roots called coralloid roots and are green in color despite not actively photosynthesizing. The filamentous cyanobacteria belonging to the genus Nostoc, which is able to form symbiosis with a wide range of organisms, inhabits the mucilage in the microaerobic and dark intercellular zone in between the inner and outer cortex of coralloid roots. This zone is transversed and connected by elongated Zamia cells.

Mucilage-tipped bracts and immature flower of Passiflora foetida, a protocarnivorous plant. A protocarnivorous plant (sometimes also paracarnivorous, subcarnivorous, or borderline carnivore), according to some definitions, traps and kills insects or other animals but lacks the ability to either directly digest or absorb nutrients from its prey like a carnivorous plant. The morphological adaptations such as sticky trichomes or pitfall traps of protocarnivorous plants parallel the trap structures of confirmed carnivorous plants. Some authors prefer the term "protocarnivorous" because it implies that these plants are on the evolutionary path to true carnivory, whereas others oppose the term for the same reason.

Opuntioideae have a hypodermis of at least one layer, very thick walls, and druses (aggregations of calcium oxalate crystals), and their cortical cells have enlarged nuclei; the reason for this is unknown. They also possess mucilage cells. Notably, their lack of collapsible cortical cells, ribs, and tubercles mean that they cannot absorb water or transfer it intercellularly as easily as the other cacti, so this may place evolutionary constraints on the aridity of habitats and maximum adult size. One adaptation around this problem is the evolution of flattened cladodes that allow opuntioids to swell up with water, increasing in volume without an increase in surface area risking water loss.

A sheet of washi paper is then carefully laid onto the water surface to capture the floating design. The paper, which is often made of kozo (paper mulberry), must be unsized and strong enough to withstand being immersed in water without tearing. Another method of marbling more familiar to Europeans and Americans is made on the surface of a viscous mucilage, known as size or sizing in English. While this method is often referred to as "Turkish marbling" in English and called ebru in modern Turkish, ethnic Turkic peoples were not the only practitioners of the art, as Persian, Tajiks, and people of Indian origin also made these papers.

Cyanobionts are cyanobacteria that live in symbiosis with a wide range of organisms such as terrestrial or aquatic plants; as well as, algal and fungal species. They can reside within extracellular or intracellular structures of the host. In order for a cyanobacterium to successfully form a symbiotic relationship, it must be able to exchange signals with the host, overcome defense mounted by the host, be capable of hormogonia formation, chemotaxis, heterocyst formation, as well as possess adequate resilience to reside in host tissue which may present extreme conditions, such as low oxygen levels, and/or acidic mucilage. The most well-known plant-associated cyanobionts belong to the genus Nostoc.

It produces lengthened sleep in functional nervous insomnia, and is also useful in insanity, being given with mucilage of acacia or in hot liquids, owing to its insolubility, or in large capsules. Its hypnotic power is not equal to that of chloral, but as it is not a depressant to the heart or respiration it can be used when morphine or chloral are contra-indicated. It is, however, very uncertain in its action, often failing to produce sleep when taken at bedtime, but producing drowsiness and sleep the following day. The drowsiness the next day following a medicinal dose can be avoided by a saline laxative the morning after its administration.

Handke wished to challenge the relationship of language and reality and to make the audience "intensely, unbearably conscious of the fundamentally arbitrary connections between words and things, until the linguistic mucilage that holds the world and our minds together crumbles."Richard Locke "A Literary Troublemaker", The New York Times, 8 June 1972 The most prominent way of how Handke challenged the meaning of language is found at the very end of the play. The actors first begin to compliment the audience on how perfect they were and then proceed to call them various insults. The names the actors call the audience seem to become more and more random.

Crystal morphology and the distribution of raphides (in roots or leaves or tubers etc.) is similar in some taxa but different in others leaving possible opportunities for plant key characteristics and systematic identification; mucilage in raphide containing cells makes light microscopy difficult, though. Little is known about the mechanisms of sequestration or indeed the reason for accumulation of raphides but it is most likely as a defense mechanism against herbivory. It has also been suggested that in some cases raphides may help form plant skeletal structure. Raphides typically occur in parenchyma cells in aerial organs especially the leaves, and are generally confined to the mesophyll.

Plumbago indica Plumbago zeylanica The species include herbaceous plants and shrubs growing to tall. The leaves are spirally arranged, simple, entire, long, with a tapered base and often with a hairy margin. The flowers are white, blue, purple, red, or pink, with a tubular corolla with five petal-like lobes; they are produced in racemes. The flower calyx has glandular trichomes (hairs), which secrete a sticky mucilage that is capable of trapping and killing insects; it is unclear what the purpose of these trichomes is; protection from pollination by way of "crawlers" (ants and other insects that typically do not transfer pollen between individual plants), or possible protocarnivory.

In order to reduce the contamination generated by the wet process of coffee fruits, scientists at Cenicafé developed a technology that avoids using water when not needed and uses the right water when needed. The technology, called Becolsub (taken from the initials of the Spanish for ecological wet coffee process with by-products handling: Beneficio Ecologicos Sub-productos), controls more than 90% of the contamination generated by its predecessor. The quality of the coffee processed this way is the same as for coffee processed by natural fermentation. The Becolsub technology consists of pulping without water, mechanical demucilaging and mixing the by-products (fruit outer-skin and mucilage) in a screw conveyor.

Psyllium husk Psyllium , or ispaghula (isabgol) , is the common name used for several members of the plant genus Plantago whose seeds are used commercially for the production of mucilage. Psyllium is mainly used as a dietary fiber to relieve symptoms of both constipation and mild diarrhea, and occasionally as a food thickener. It is commonly used as a food ingredient in manufactured breakfast cereals which may contribute to a healthy lifestyle by improving blood cholesterol levels and gastrointestinal function. Use of psyllium in the diet for three weeks or longer lowers blood cholesterol levels in people with elevated cholesterol, and lowers blood glucose levels in people with type 2 diabetes.

Linola was developed in Australia and introduced in the 1990s with less omega-3, specifically to serve as fodder. Another disadvantage of the meal and seed is that it contains a vitamin B6 (pyridoxine) antagonist, and may require this vitamin be supplemented, especially in chickens, and furthermore linseeds contain 2-7% of mucilage (fibre), which may be beneficial in humans and cattle, but cannot be digested by non-ruminants and can be detrimental to young animals, unless possibly treated with enzymes. Linseed meal is added to cattle feed as a protein supplement. It can only be added at low percentages due to the high fat content, which is unhealthy for ruminants.

This erect stance helps to avoid rot due to the swamp like nature of the white sand savannahs and also ensures that the plant can stay above water if minor flooding occurs to maintain efficient access to sunlight. Over time, while approaching maturity, the blades narrow to 0.5–1 mm in width and grow to a length of 80–150 mm. their new morphology is cuneate (wedge shaped) at the base of the leaves and becomes acute approaching the apex. Being a carnivorous plant, the leaves are coated with both stalked glands, which secrete a sweet mucilage to attract potential prey, and sessile glands, which are both located on the adaxial surface.

D. rotundifolia with the remains of a butterfly The plant feeds on insects, which are attracted to the glistening drops of mucilage, loaded with a sugary substance, covering its leaves. It has evolved this carnivorous behaviour in response to its habitat, which is usually poor in nutrients or is so acidic that nutrient availability is severely decreased. The plant uses enzymes to dissolve the insects – which become stuck to the glandular tentacles – and extract ammonia (from proteins) and other nutrients from their bodies. The ammonia replaces the nitrogen that other plants absorb from the soil, and plants that are placed in a high-nitrogen environment rely less upon nitrogen from captured insects.

Coffee cherries being separated using water in separation vats Water used in processing coffee leaves the coffee processing unit with high levels of pollution. The main component is organic matter, stemming from de-pulping and mucilage removal. The majority of organic material in the wastewater is highly resistant and COD values, the amount oxygen required to stabilize organic matter by using a strong oxidant, make up 80% of the pollution load, with values as high as 50 g/l. The BOD, the amount of oxygen required for the biological decomposition of organic matter under aerobic conditions at a standardized temperature and time of incubation, coming from biodegradable organic material can reach values of 20 g/l.

S. marcescens was discovered in 1819 by Venetian pharmacist Bartolomeo Bizio, as the cause of an episode of blood-red discoloration of polenta in the city of Padua. Bizio named the organism four years later in honor of Serafino Serrati, a physicist who developed an early steamboat; the epithet marcescens (Latin for "decaying") was chosen because of the pigment's rapid deterioration (Bizio's observations led him to believe that the organism decayed into a mucilage-like substance upon reaching maturity).Bizio's original report was translated into English in 1924, and published in the Journal of Bacteriology. See Serratia was later renamed Monas prodigiosus and Bacillus prodigiosus before Bizio's original name was restored in the 1920s.

There was also evidence of fine-scale genetic structure, with plants tending to be more closely related to nearby plants than to more distant plants. The authors suggest that gene flow was probably always limited in these populations, even before they were fragmented. Banksia sphaerocarpa is one of five closely related Banksia species that have highly unusual flower nectar. Whereas other Banksia species produce nectar that is clear and watery, the nectar of these species is pale yellow initially, but gradually becomes darker and thicker, changing to a thick, olive-green mucilage within one to two days of secretion, and eventually becoming "an almost black, gelatinous lump adhering to the base of the flowers".

Nitrocellulose adhesive dispensed from a tube Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, or welding. These include the ability to bind different materials together, the more efficient distribution of stress across a joint, the cost-effectiveness of an easily mechanized process, and greater flexibility in design. Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing.

The molecular and physiological data implies that the Venus flytrap (Dionaea) and Aldrovanda snap-traps evolved from the flypaper traps of a common ancestor with the Drosera; the living evidence of a link between Drosera and Dionaea is D. regia and its remnant characteristics. In this evolutionary model, pre-adaptations to evolution into snap-traps were identified in several species of Drosera, such as rapid leaf and tentacle movement. The model proposes that plant carnivory by snap-trap evolved from the flypaper traps of Drosera, driven by increasing prey size. Larger prey can easily escape the sticky mucilage of flypaper traps; the evolution of snap- traps would largely prevent escape and kleptoparasitism (theft of prey captured by the plant before it can derive any benefit from it).

Whereas other Banksia species produce nectar that is clear and watery, the nectar of these species is pale yellow initially, but gradually becomes darker and thicker, changing to a thick, olive-green mucilage within one to two days of secretion. (only abstract sighted) In the case of B. telmatiaea, it eventually becomes "an almost black, gelatinous lump adhering to the base of the flowers". This unusual nectar was first noted in 1980 by Byron Lamont, who attributed its transformation to the cyanobacteria that he observed feeding off the nectar sugars. Noting that many of these cyanobacteria had heterocysts, he speculated that they aid the plant by fixing atmospheric nitrogen, which is then washed off the flower heads by rain, and absorbed by the proteoid root mat.

The development of rhizomorphs begins with a submerged thallus that produces mycelium (hyphae biomass) that when deprived of nutrients and exposed to increasing oxygen, morphogenesis occurs giving rise to pseudo or microsclerotia (survival structures of some fungi), which precede rhizomorph development. Concentrations of oxygen play an important role in the production of rhizomorphs. When there is a high concentration of oxygen in the atmosphere, soil moisture, temperature and pH, rhizomorph production increases. Rhizomorphs contain four differentiated types of tissues #The outer layers are a compact growing point that make up the mucilage #The melanized wall that serves as protection against colonization by another microorganisms (bacteria or fungi) #The medulla that serves for conduction of water and dissolves nutrients #The central line used as an air conducting channel.

Sea foam usually contains a mixture of decomposed organic materials The composition of sea foam is generally a mixture of decomposed organic materials, including zooplankton, phytoplankton, algae (including diatoms), bacteria, fungi, protozoans, and vascular plant detritus, though each occurrence of sea foam varies in its specific contents. In some areas, sea foam is found to be made up of primarily protein, dominant in both fresh and old foam, as well as lipids and carbohydrates. The high protein and low carbohydrate concentration suggest that sugars originally present in the surrounding mucilage created by algae or plant matter has been quickly consumed by bacteria. Additional research has shown that a small fraction of the dry weight in sea foam is organic carbon, which contains phenolics, sugars, amino sugars, and amino acids.

Banksia leptophylla is one of five Banksia species, all closely related to B. sphaerocarpa, that have highly unusual flower nectar.

No names of the engineers were recorded or appear in the inscriptions on the bridges, which give only the names of local officials who sponsored them and oversaw their construction and repair. However, there might have been an engineering school in Fujian, headed by a prominent engineer known as Cai Xiang (1012–1067), who had risen to the position of governmental prefect in Fujian. Between 1053 and 1059, he planned and supervised the construction of the large Wanan Bridge (once called the Luoyang Bridge) near Quanzhou (on the border of the present- day Luojiang District and Huai'an County. This bridge, a stone structure similar to a number of other bridges found in Fujian, still stands, and features ship-like piers bound to their bases using mucilage from oysters as an adhesive.

Like a number of other plants in several plant families, its seeds contain a substance known as mucilage, a condition known as myxospermy. Recently, this has been demonstrated experimentally to perform the function of trapping nematodes, as a form of 'protocarnivory'Nature - Evidence for Facultative Protocarnivory in Capsella bursa-pastoris seedsTelegraph - Tomatoes Can Eat Insects Capsella bursa-pastoris is closely related to the model organism such as Arabidopsis thaliana and is also used as a model organism, due to the variety of genes expressed throughout its life cycle that can be compared to genes that are well studied in A. thaliana. Unlike most flowering plants, it flowers almost all year round. Like other annual ruderals exploiting disturbed ground, C. bursa-pastoris reproduces entirely from seed, has a long soil seed bank, and short generation time, and is capable of producing several generations each year.

Within these regions, various methods emerged in which colors were made to float on the surface of a bath of viscous liquid mucilage or size, made from various plants. These include katheera or kitre- gum tragacanth (Astragalus often used as a binder by apothecaries in making tablets), shambalîleh or methi- fenugreek seed (an ingredient in curry mixtures), and sahlab or salep (the roots of "Orchis mascula", which is commonly used to make a popular beverage). A pair of leaves bearing rudimentary drop-motifs are considered among the earliest examples of this paper, held in the Kronos Collection. One of the sheets bears an accession notation on the reverse stating "These abris are rare" (یاد داشت این ابریهای نادره است) and adds that it was "among the gifts from Iran" to the royal library of Ghiyath Shah, the ruler of the Malwa Sultanate, dated Hijri year 1 Dhu al-Hijjah 901/11 August 1496 of the Common Era.
