Chemical Characterization of Exopolysaccharides from Antarctic Marine Bacteria

Production 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 ...

Exopolysaccharides from Marine and Marine Extremophilic Bacteria: Structures, Properties, Ecological Roles and Applications

The marine environment is the largest aquatic ecosystem on Earth and it harbours microorganisms responsible for more than 50% of total biomass of prokaryotes in the world. All these microorganisms produce extracellular polymers that constitute a substantial part of the dissolved organic carbon, often in the form of exopolysaccharides (EPS). In addition, the production of these polymers is often...

Biological functions of exopolysaccharides from probiotic bacteria

Probiotic bacteria have the ability to produce exocellular polymers called exopolysaccharides (EPS). It has been suggested that the health benefit of probiotic bacteria can be attributed to the production of EPS. However, the composition, structure and biological functions of EPS may vary depending on the type of microorganism and environmental conditions. Some data suggest that EPS production ...
