BACKGROUND Marine snow (small amorphous aggregates with colloidal properties) is present in all oceans of the world. Surface water warming and the consequent increase of water column stability can favour the coalescence of marine snow into marine mucilage, large marine aggregates representing an ephemeral and extreme habitat. Marine mucilage characterize aquatic systems with altered environment...

SO4 has been used to investigate the production of extracellular mucilage by log-phase cells. Uptake of isotope occurs most rapidly in the light, when cells are actively dividing. The mucilage comprises about 50 % carbohydrate, 16% protein and 10 % sulphate. The major sugar is xylose; uronic acid, a small amount of galactose, glucose (trace) and 2 reducing substances are also present. Methylati...

JORDAN, M. S. & W. J. HAYDEN (1992). A Survey of Mucilaginous Testa in Chamaesyce. Collect. Bot. (Barcelona) 21 :79-89. Seeds of Chamaesyce were studied for presence of mucilaginous testa. Samples were selected to represent all major systematic sections within the genus. Observations were made with a dissecting microscope following brief hydration of seeds; additional SEM observations of both i...

Pectins are major components of plant primary cell walls. They include homogalacturonans (HGs), which are the most abundant pectin and can be the target of apoplastic enzymes like pectin methylesterases (PMEs) that control their methylesterification level. Several PMEs are expressed in the seed coat of Arabidopsis thaliana, particularly in mucilage secretory cells (MSCs). On the basis of public...

BACKGROUND The dilution and rapid elimination of topically applied drugs due to the flushing action of saliva is a major difficulty in the effort to eradicate infections of oral cavity. Utilization a proper delivery system for incorporation of drugs has a major impact on drug delivery and such a system should be formulated for prolonged drug retention in oral cavity. OBJECTIVES The aim of the...

Linseed lipid in the dietary composition is a major factor influencing the fatty acid composition of milk from ruminants, because fatty acids which reach the duodenum are, at least in part, of dietary origin as well as the result of ruminal microbial biohydrogenation of dietary lipids. In this review, the effect of linseed lipid on ruminal fatty acid metabolism, nutrient digestibility, microbia...

Replacing dietary grass silage (GS) with maize silage (MS) and dietary fat supplements may reduce milk concentration of specific saturated fatty acids (SFA) and can reduce methane production by dairy cows. The present study investigated the effect of feeding an extruded linseed supplement on milk fatty acid (FA) composition and methane production of lactating dairy cows, and whether basal forag...

The adsorption of radioactive mucilage by pathogenic fungi was shown to be dependent upon time, the composition of mucilage, the type of fungal surface (conidia, hyphae, hyphal apices), fungal species, pH and bivalent cations. All fungal adhesins were inactivated by either proteinase or polysaccharase treatments. Adsorption was not inhibited by the numberous mono-, di- and oligo-saccharides tha...

this study was conducted to evaluate the effects of extruded linseed on milk production, dry matter intake and reproduction performance of 300 holstein lactating cows (35±15 days in milk; 41±9/8 kg/day of milk production). cows were utilized in a completely randomized experimental design, comprised of: 2 treatments (concentrate containing 7 percent extruded linseed vs control) with a number of ...

A microwave assisted extraction technique was developed to optimize the extraction of mucilage from the fruits of Abelmoschus esculentus plant. The plant has been extracted by conventional and microwave assisted methods for the isolation of mucilage. Microwave extraction at 160 W intensity and 40 min heating duration increase 11.55% in the yield of mucilage when compared to 1 h conventional hea...
