PROCESS FOR PREPARING HETEROPOLYSACCHARIDE S-657 |
摘要 |
Heteropolysaccharide S-657 is a new heteropolysaccharide. It 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 rhamnose and glucose in the approximate molar ratio of 2 : 1. It can be prepared by fermentation of a new strain of Xanthomonas campestris, ETCC 53159. It has valuable properties as a thickening, suspending and stabilizing agent in aqueous solutions and is especially valuable for use in well-treating fluids. |
