Abstract
Azotobacter vinelandii MTCC 2460, a novel exopolysaccharide (EPS) prod ucer, was isolated from Nelumbium nelumbo (lotus) stem. The EPS produc ed has a sugar composition different from that of existing industrial gums. Optimization of the basal medium composition and other physical parameters viz. pH, temperature and time has been reported in this pap er. A final yield of 30% of the amount of carbon source i.e. sucrose, supplied has been obtained in shake flask cultures, indicating the pot ential of the organism for production of useful EPS on a large (indust rial) scale.
