Abstract:
A marine exopolysaccharide (EPS) producing bacterium was isolated from a sponge sample at about 16 m depth in red sea (Huraghada, Egypt). Phenotypic characterization demonstrated that, the bacterium is a gram negative rod motile by means of single polar flagellum, showing wide range of carbohydrate utilization. Phylogenetic analysis based on 16S Ribosomal deoxyribonucleic acid (rDNA) sequence revealed 99% homology with Pseudoalteromonas sp., accordingly the name Pseudoalteromonas sp. AM was proposed. Maximum EPS productivity was achieved after 7 days at pH 7, agitation of 150 rpm in a fermentation medium containing glucose, meat extract
