Chemical composition of two exopolysaccharides from Bacillus thermoantarcticus
Article Abstract:
The thermophilic bacterium, Bacillus thermoantarcticus, produces 2 microbial exocellular polysaccharides, EPS1 and EPS2, which contain sulfate groups. The presence of mannose as the carbon and energy source increases the yield of the EPS. EPS1 is composed of 4 different alpha-D-mannoses and 3 different beta-D-glucoses which is related to xanthan polymers. EPS2 consists of 4 different alpha-D-mannoses and some amount of pyruvic acid. EPS1 represents 27% of the total carbohydrate fraction, whereas EPS2 represents 71% of the total fraction.

Culture conditions determine the balance between two different exopolysaccharides produced by Lactobacillus pentosus LPS26
Article Abstract:
The production of two different epoxypolysaccharides (EPSs) by Lactobacillus pentosus LPS26, a strain isolated from a natural fermentation of olives, is studied. The analysis has shown that culture conditions have a major impact on the type and concentration of EPS produced by strain LPS26 and these conditions should be selected carefully for optimization and application studies.

Influence of nutritional factors on the nature, yield, and composition of exopolysaccharides produced by Gluconacetobacter xylinus I-2281
Article Abstract:
Research reveals that nutritional factors exert a strong influence on the yield and nature of the exopolysaccharides produced by Gluconacetobacter xylinus I-2281. Data indicate that fructose and sucrose are the appropriate substrates for gluconacetan production, while glucose is not. Furthermore, in G. xylinus I-2281, production of biomass and exopolysacchardies is dissociated.
