Heteropolysaccharide S-194

摘要

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.
