Exopolysaccharides enriched in rare sugars: bacterial sources, production, and applications
Microbial extracellular polysaccharides (EPS), produced by a wide range of bacteria, are high molecular weight biopolymers, presenting an extreme diversity in terms of chemical structure and composition. They may be used in many applications, depending on their chemical and physical properties. A rather unexplored aspect is the presence of rare sugars in the composition of some EPS. Rare sugars...
متن کاملProduction of exopolysaccharides by Antarctic marine bacterial isolates.
AIMS This study was undertaken to examine and characterize Antarctic marine bacterial isolates and the exopolysaccharides (EPS) they produce in laboratory culture. METHODS AND RESULTS Two EPS-producing bacterial strains CAM025 and CAM036 were isolated from particulate material sampled from seawater and sea ice in the southern ocean. Analyses of 16S rDNA sequences placed these isolates in the ...
متن کاملBacterial Exopolysaccharides: Functionality and Prospects
Diverse structural, functional and valuable polysaccharides are synthesized by bacteria of all taxa and secreted into the external environment. These polysaccharides are referred to as exopolysaccharides and they may either be homopolymeric or heteropolymeric in composition and of diverse high molecular weights (10 to 1000 kDa). The material properties of exopolysaccharides have revolutionized...
متن کاملBacterial exopolysaccharides: biosynthesis pathways and engineering strategies
Bacteria produce a wide range of exopolysaccharides which are synthesized via different biosynthesis pathways. The genes responsible for synthesis are often clustered within the genome of the respective production organism. A better understanding of the fundamental processes involved in exopolysaccharide biosynthesis and the regulation of these processes is critical toward genetic, metabolic an...
متن کاملMicrobial exopolysaccharides-structural subtleties and their consequences
Microbial extracellular heteropolysaccharides are mainly linear molecules to which side chains of varying length and complexity are attached at regular intervals. Examination of 'families' of microbial exopolysacchaiide with closely related structures enables us to determine the effect of minor (or major) changes to structure on the physical properties of these macromolecules. Changes may also ...
