Finn, R K; Tannahill, A L; Laptewicz, J E

A new heteropolysaccharide polymer and a method for producing this polymer are described. The polymer is made in a fermentation process comprising culturing a heteropolysaccharide-producing strain of a microorganism of the genus Methylomonas on an aqueous culture medium containing methanol as the sole source of assimilable carbon. Several uses for the heteropolysaccharide also are discussed, such as its use as a drag reducing agent, a thickening agent, an emulsifier, a soil suspending agent, and a flocculant or deflocculant.
