ABSTRACT:
The new heteropolysaccharide S-657, prepared by fermentation of a new strain of Xanthomonas campestris, ATCC 53159, has valuable properties as a thickening, suspending and stabilizing agent in aqueous solutions and is especially valuable for use in well treating fluids.
Heteropolysaccharide S-657 is composed principally of carbohydrate, about 12% protein and about 7% (calculated as O-acetyl) acyl groups, the carbohydrate portion containing about 19% glucuronic acid, and the neutral sugars rhamnose and glucose in the approximate molar ratio of 2:1.
