  • Polysaccharide and bacterial fermentation process for its preparation
    Patent number: 3960832
    Abstract: A process for producing a novel heteropolysaccharide by a bacterial fermentation in which a new bacteria is incubated in a final fermentation medium containing a suitable carbohydrate source, a source of magnesium ions, a source of phosphorus and nitrogen, and water, the incubation taking place at a temperature of about 25 to 35.degree.C. for about 35 to 60 hours. The heteropolysaccharide produced by the above process are used to thicken aqueous media. Compositions containing the above polysaccharide in combination with certain salts containing di- and trivalent metal ions are useful for example, in drilling fluids, paint compositions, polishes and as additives for foods.
