摘要:
A novel polysaccharide S-60 is disclosed composed of principally carbohydrate, 10-15% protein, and 3-4.5% acetyl groups as the O-glycosidically linked ester. The carbohydrate portion contains ~12% uronic acid (based on wt. gum) and the neutral sugars rhamnose and glucose, the latter having an approximate molar ratio of 1.5 to 1. This polysaccharide is produced by an unnamed Pseudomonas species, ATCC 31461. in a suitable fermentation medium. Deacetylated polysaccharide S-60 is also disclosed. It has valuable properties in both the clarified and non-clarified form and is useful as an agar substitute or as a shapeable room deodorant.

Heteropolysaccharide S-119 is produced by bacterial fermentation of an organism deposited with the American Type Culture Collection under Accession No. ATCC 31643. Pure cultures of this organism are novel.
