Abstract
A novel polysaccharide S-194 is disclosed composed of principally carbohydrate, about 14% protein, and 9-11% O-acetyl groups. The carbohydrate portion comprises about 8.8-9.2% glucuronic acid and the neutral sugars glucose and rhamnose in the approximate molar ratio 4:1. This polysaccharide is produced by a new Alcaligenes species ATCC 31961, in a suitable fermentation medium.
Claims7
A biologically pure culture of an Alcaligenes microorganism, ATCC 31961.
A culture consisting essentially of Alcaligenes microorganism, ATCC 31961, said culture being capable of producing heteropolysaccharide S-194 in recoverable amounts by submerged, aerobic fermentation of an assimilable carbon source.
A process for producing heteropolysaccharide S-194 which comprises growing the organism ATCC 31961 in an aqueous nutrient medium by submerged, aerobic fermentation of an assimilable carbon source and recovering said heteropolysaccharide S-194.
