ABSTRACT:
Disclosed are novel polysaccharides having the following physicochemical properties: (1) a molecular weight determined by gel filtration chromatography is about 5.times.10.sup.3 to 10.times.10.sup.6, (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 .alpha., that of L-rhamnose is .beta. and that of D-glucose is .alpha.. 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.
