[Physicochemical properties of an extracellular polysaccharide isolated from culture media of Bacillus amyloliquefaciens].
A new extracellular polysaccharide has been isolated by chromatography on anion exchanger of a fraction obtained from highly viscous culture media of Bacillus amyloliquefaciens. This polysaccharide is characterised by high molecular weight (1,000,000 dalton) and intrinsic viscosity (323 ml/g). It contains 24% neutral sugar (galactose and mannose 5:1), 35% glucuronic acid and 51.5% N-acetylhexosamines (N-actylglucosamine, N-acetylgalactosamine and N-acetylbacillosamine 6:9:1).
