Hepatitis C virus (HCV) has infected 3% of the population worldwide and 20% of the population in Egypt. HCV infection can lead to hepatocellular carcinoma and death. The presently available treatment with interferon plus ribavirin, has limited benefits due to adverse side effects. Seaweeds have become a major source of new compounds to treat viral diseases. This work aimed to study the effect o...

Ferulate polysaccharide esters in grasses enter into free-radical condensation reactions in the cell wall. By radical dimerisation of ferulates, polysaccharide–polysaccharide cross-linking is eþ ected. A range of diferulate isomers are produced, not solely the 5-5o-coupled dimer which has been quantiüed historically. Both ferulates and diferulates enter ligniücation reactions and become intimat...

Changes in neutral sugar, uronic acid, and protein content of tomato (Lycopersicon esculentum Mill) cell walls during ripening were characterized. The only components to decline in amount were galactose, arabinose, and galacturonic acid. Isolated cell walls of ripening fruit contained a water-soluble polyuronide, possibly a product of in vivo polygalacturonase action. This polyuronide and the o...

Aerobic granular sludge was cultivated adopting internal-circulate sequencing batch airlift reactor. The contradistinctive experiment about short-term membrane fouling between aerobic granular sludge system and activated sludge system were investigated. The membrane foulants was also characterized by Fourier transform infrared (FTIR) spectroscopy technique. The results showed that the aerobic g...

The polysaccharide maltodextrin (Mdx) can provide a low cost alternative to substitute the fractioned dextran for the use with polyethylene glycol (PEG) in aqueous two-phase polymer polymers systems. Aqueous two-phase system (ATPS) partitioning has been used to recover and concentrate proteins from Shrimp Waste and offers many advantages along with biomass removal. In this work we have studied ...

Bacteroides is an abundant genus of bacteria of the human intestinal microbiota. Bacteroides species synthesize a large number of capsular polysaccharides (PS), a biological property not shared with closely related oral species, suggesting importance for intestinal survival. Bacteroides fragilis, for example, synthesizes eight capsular polysaccharides per strain, each of which phase varies via ...

Corpe, William A. (Columbia University, New York, N.Y.). Factors influencing growth and polysaccharide formation by strains of Chromobacterium violaceum. J. Bacteriol. 88:1433-1441. 1964.-Gelatinous Chromobacterium violaceum strains elaborate a fibrous exopolysaccharide that forms a matrix in which growing cells are embedded. Stable, nongelatinous variants arising from gelatinous cultures were ...

Ganoderma lucidum is commonly used in Vietnam and other countries since more than 4000 years ago with excellent beneficial health effects Lingzhi has potential applications as a functional product with polysaccharide, and many other healthy components. This polysaccharide obtained good application in human. Lingzhi becomes a common mushroom in Vietnam, growing almost all year. The fruit of this...

Porphyridium cultures grown on either nitrate or ammonium as the nitrogen source showed similar patterns of growth and cell wall polysaccharide production. The effect of nitrogen on growth and cell wall polysaccharide production was studied by applying three regimens of supply: batch mode, in which nitrate was supplied at the beginning of the experiment and became depleted at day 6; continual m...
