Abstract

Proposed is a process of recovering polysaccharides in granular, free-flowing form produced by bacteria of the species Xanthomonas or Arthrobacter, wherein the polysaccharides are precipitated by the addition of the precipitating liquid to the fermentation medium, are then separated, washed with an organic liquid which is preferably also employed as the precipitating liquid, are then washed, separated and subsequently dried, the polysaccharide particles being coarsely separated from the washing liquid after washing, kept in motion with the addition of water and subsequently dried, preferably with continued motion.
