Exopolysaccharides producing bacteria was isolated from marine sediment soil. Optimization was done to get maximum EPS production, for those parameters such as pH 8, temperature 30C, galactose, yeast extract, sodium nitrate, Ferrous sulphate, Tween 80, NaCl 7% and Tris Hcl buffer. The physicochemical characterization was done for the EPS crude extract obtained from Halomonas sp. The bacterial EPS extract revealed characteristic absorption bands of EPS for Halomonas characterized by FT-IR, GC- MS and NMR analysis. Antimicrobial activity was analyzed for bacterial EPS extract which shows higher zone in Klebsiella sp and Aspergillus ochraceus.
