Abstract
Isolation and Identification of an Exopolysaccharides-Producing Shewanella frigidimarina Strain W32-2 from Antarctic Sediments
Exopolysaccharides (EPSs) produced by a number of bacteria genera are very attractive to food industries because of their stabilizing and interesting properties. Shewanella strain W32-2, EPSs-producing bacteria, was isolated from Antarctic sediments by method of phenol-sulfuric acid and alcohol precipitation. The optimal growing condition and biological properties of the produced EPS were investigated. The EPS yield of the strain reached at 109.56 mg·L-1. Phylogenetic analysis showed that the strain W32-2 was identified to be a species of Shewanella frigidimarina.
