• An exopolysaccharide-producing Gram negative bacterium was isolated and determined to be a Sphingomonas sp. (CS101). A sugar composition analysis of an exopolysaccharide indicated that the Sphingomonas sp. CS101 secreted an exopolysaccharide composed of glucose, mannose, fucose, and rhamnose in the ratio of 2.1:1.1:1.0:0.1, suggesting that this exoplysaccharide is an unusual type of sphingan family. The mean molecular weight of the exopolysaccharide was determined to be 4.2×105 Da by size exclusion chromatography coupled with multi-angle laser-light scattering (SEC/MALLS) analysis. An exopolysaccharide was produced up to 17 g/l (pH 7; 30 °C) with the optimal medium condition over 4 days of cultivation.
