PRODUCTION OF BACTERIAL POLYSACCHARIDES

摘要

Polysaccharides are produced by single stage continuous culture of Xanthomonas bacteria, especially Xanthomonas juglandis in a chemically-defined simple salt medium. Cultures have been run for over 2,000 hours without reduction in the polysaccharide yield. The physical and chemical properties of the product can be controlled by selection of the limiting nutrilite in the culture medium to give a wide range of polysaccharides suitable for various applications,
