PRODUCTION OF HEAT MODIFIED HETEROPOLYSACCHARIDES

摘要

This invention provides a process which involves cultivating a strain of Methylophilus viscogenes under growth conditions to produce an aqueous solution of an accumulated quantity of an exopolysaccharide, such as heteropolysaccharide Poly 54, and heating the aqueous solution to produce heat-modified exopolysaccharide which imparts enhanced pseudoplastic and thixotropic properties to aqueous solutions.
