Abstract:

In this study,the effects of major environmental factors on the growth and EPS production of Antarctic bacteria S-15-13 were investigated.Meanwhile,the cloned 16S rDNA and other 24 related sequences were included in the consensus phylogenetic analysis by using neighboring- joining method.The results showed that the optimal conditions for EPS production were culture period,56h;growth temperature,8℃;carbon source,1.0% glucose;NaCl concentration,3. 0%;pH 6.0-7.0.Phylogenetic analysis indicated that strain S-15-13 belong to Pseudoaltero- monas sp.
