Abstract
Xanthan gum is recovered from an aqueous fermented broth containing the gum by adding to the broth a sub-precipitant amount of organic solvent such an isopropanol, removing solids from the broth at 100.degree. C. or more, eg. by filtration, and precipitating the gum by addition of more organic solvent. Heat degradation of the gum during the solids removal is thereby lessened.
