Exopolysaccharides (EPSs) are polymers with large molecular weight that consist of various residues of sugar. These are desired because the substitution of synthetic polymers is degradable and non-toxic. Most microorganisms have the ability to synthesize and excrete exo polysaccharides with new chemical compositions, characteristics and structures in order to have important applications in various areas. The current study based on marine bacterial isolates screening the production of exo polysaccharide. Among the four exopolysaccharide producing isolates, the isolate PMSS12 had the highest production of exo polysaccharides. The efficient marine bacterial isolate PMSS12 was further identified by sequence of 16S rRNA. The PMSS12 isolate was confirmed as Bacillus megaterium. Then the exopolysaccharide produced by Bacillus megaterium was characterized by using FTIR, NMR and SEM.
