A water soluble or swellable polymer gel is dispersed into a liquid phase to form a fluid composition and is worked while in that composition. The liquid phase is an aqueous solution of an equilibrating agent that substantially prevents aggregation of the particles or dissolution of the polymer during the working. The working may be, for instance, milling, extraction of impurities, extraction of w...

A process of recovering polysaccharides in granular, free-flowing form produced by bacteria of the species Xanthomonas or Arthrobacter is disclosed, 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, sepa...
