Disclosed are novel polysaccharides having the following physicochemical properties: (1) a molecular weight determined by gel filtration chromatography is about 5 × 10³ to 10 × 10⁶, (2) the constituent glycoses are D-galacturonic acid, L-rhamnose and D-glucose, (3) the constituent glycoses are joined substantially by 1,3-linkages, and (4) a configuration of D-galacturonic acid is α, that of L-rhamnose is β and that of D-glucose is α. A process for producing polysaccharides composed of D-galacturonic acid, L-rhamnose and D-glucose, use of the polysaccharides and a strain for producing the polysaccharides are also disclosed. |
