FIELD: biotechnology.
SUBSTANCE: method of producing xanthan is proposed. Culturing the bacteria culture Xanthomonas campestris RNCM B-2228 is carried out on a nutrient medium under aeration. The nutrient medium comprises a preliminary hydrolysed low-grade timber, nitrogen sources, mineral salts. Xanthan is isolated from the culture liquid by extraction with low monohydric alcohol.
EFFECT: increased efficiency of producing xanthan.
