Abstract: A process for purifying 1,3-propanediol from the fermentation broth of a cultured E. coli that has been bioengineered to synthesize 1,3-propanediol from sugar is provided. The basic process entails filtration, ion exchange and distillation of the fermentation broth product stream, preferably including chemical reduction of the product during the distillation procedure. Also provided are highly purified compositions of 1,3-propanediol.

CPC classification number: C08B37/0003 , C08B37/0033
Abstract: Processes are disclosed for the purification and recovery of polysaccharide gums from an aqueous solution, particularly xanthan gum from a fermentation broth. An aqueous solution of at least one polysaccharide gum is mixed with a non-solvent stream comprising water and a subprecipitant level of a non-solvent of the polysaccharide gum. The mixture is concentrated to increase the polysaccharide gum concentration, and optionally undergoes a heat treatment. Additional non-solvent is added to the concentrated mixture to precipitate the polysaccharide gum. The precipitated gum is dried after being separated from the liquid component of the mixture. The removed liquid component can be recycled to the earlier step in the process in which the polysaccharide gum solution is mixed with the non-solvent stream.
