Mucoid strains of Pseudomonas aeruginosa produce a high-molecular-weight exopolysaccharide called alginate that is modified by the addition of O-acetyl groups. To better understand the acetylation process, a gene involved in alginate acetylation called algF was identified in this study. We hypothesized that a gene involved in alginate acetylation would be located within the alginate biosyntheti...

background: alginate is a linear polysaccharide consisting of guluronate (polyg) and mannuronate (polym) subunits. methods: in the initial screening of alginate-degrading bacteria from soil, 10 isolates were able to grow on minimal medium containing alginate. the optimization of cell growth and alginate lyase (algl) production was carried out by the addition of 0.8% alginate and 0.2-0.3 m nacl ...

A diabetic foot ulcer is an open wound that can become sore and frequently occurs in patients. Alginate has the ability to form a hydrophilic gel when contact with surface Xanthones are main compounds of mangosteen rind have antibacterial anti-inflammatory properties. The purpose this research was evaluate healing antioxidants assay combination alginate from S. ilicifolium extracts on mice mode...

Background Alginate is a polysaccharide constituted by β-d-mannuronic acid and α-l-guluronic which has several applications in the field of tissue engineering, drug delivery other biomedical applications. This study aimed to evaluate production, molecular weight (MW) viscosifying power alginate produced strain AT9 cultured 3-L reactor, under three different oxygen transfer rates (OTR). Results ...

Alginate is a linear anionic heteropolysaccharide with chemical structure consisting of 1,4-linked subunits β-D-mannuronic acid (M) and its C-5 epimer α-L-guluronic (G). It well known that the monomer composition molecular weight alginates affect their properties influence use in food pharmaceutical industries. usually extracted from seaweed for commercial purposes, but can also be produced by ...

Prospecting macroalgae (seaweeds) as feedstocks for bioconversion into biofuels and commodity chemical compounds is limited primarily by the availability of tractable microorganisms that can metabolize alginate polysaccharides. Here, we present the discovery of a 36-kilo-base pair DNA fragment from Vibrio splendidus encoding enzymes for alginate transport and metabolism. The genomic integration...

Alginates are classed as a dietary fibre and have been shown to inhibit digestive enzymes in vitro, and therefore could be used as an obesity treatment. The current study aims to assess whether alginate in a bread vehicle maintains its inhibition properties despite cooking and digestion, and may therefore be used as a potential treatment for obesity. After 180 min in a model gut that replicates...

Abstract In the present study, effects of dietary supplementation low molecular weight sodium alginate on growth, body composition, antioxidant enzymes, digestive and immune response in yellowfin sea bream juvenile ( Acanthopagrus latus ) were investigated. Fish (n=180) divided into 3 groups with replicates received treatments including basal diet without (control treatment), containing 5 g per...
