Lindblom, G P; Patton, J T

This is a process for the production of heteropolysaccharides by fermenting carbohydrates with bacteria of the genus Xanthomonas. These water-soluble polymers have potential applications as film-forming materials; as thickeners or body-building agents in oil- field drilling muds, etc.; and as emulsifying, stabilizing, and sizing agents. The heteropolysaccharides can be produced on a continuous basis by employing a multistage process in which bacterial cells are grown on a low carbohydrate medium in a first stage and cells free of substantial quantities of polymer are then fed into a second stage with a high carbohydrate medium.
