Antarctic marine bacteria isolated from sea ice and Southern Ocean particulate material were screened for exopolysaccharide (EPS) production. Ten strains were characterized using phenotypic (morphology), chemotaxonomic (whole cell fatty acid profiles) and phylogenetic (16S rDNA sequencing) technique...
