  • Method of using heteropolysaccharides produced by the fermentation of methanol
    Patent number: 4061585
    Abstract: Disclosed is a new heteropolysaccharide polymer and a method for producing this polymer by a fermentation process comprising culturing a heteropolysaccharide-producing strain of a micro-organism of the genus Methylomonas on an aqueous culture medium containing methanol as the sole source of assimilable carbon. Several uses for the heteropolysaccharide are also disclosed such as its use as a drag reducing agent, a thickening agent, an emulsifier, a soil suspending agent and a flocculant or deflocculant.
    Type: Grant
    Filed: December 1, 1976
    Date of Patent: December 6, 1977
    Assignee: Cornell Research Foundation, Inc.
    Inventors: Robert K. Finn, Alex L. Tannahill, Joseph E. Laptewicz, Jr.
