Scleroglucan, a neutral homopolysaccaride consisting of a linear chain of β-d-(1-3)-glucopyranosyl and β-d-(1-6)-glucopyranosyl groups, was produced by pure culture fermentation from Sclerotium rolfsii MTCC 2156 by submerged culture. Fermentation process was optimized in two steps. In the first step, one-factor-at-a-time method was used to investigate the effects of medium constituents such as carbon and nitrogen sources. In the second step, concentration of medium components was optimized using an L16-orthogonal array method. In all, 10 different carbon sources and eight different nitrogen sources were evaluated. Maximum yield of 16.58 g/l was obtained in a medium containing sucrose as a carbon source and sodium nitrate and yeast extract as nitrogen source.
