Abstract
A xanthan gum-containing fermented solution is subjected to an enzyme treatment for solubilizing the microbial cells present in the fermented solution. While the fermented solution having undergone the enzyme treatment is maintained at a temperature of 50.degree. C. to 80.degree. C., and xanthan gum is precipitated by adding an hydrophilic organic solvent incapable of dissolving xanthan gum to the fermented solution. When a rotary turbine is used, the precipitate can be cut with a shearing cutter to recover a finely-divided fibrous product.
