摘要： The invention concerns a method for producing exopolysaccharides by fermenting micro-organisms characterised in that it consists in carrying out the fermentation in a nutrient medium comprising at least a source of carbon available to the micro-organisms and at least a source of nitrogen, said source being derived from a fraction of carob seed.

摘要： 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 to 80°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.
