FIELD: medicine.
SUBSTANCE: method includes heating of fermentation broth, which contains methionine and biomass and is produced in process of fermentation of microorganism-methionine producer, with further separation of biomass from fermentation broth to produce liquid phase enriched with methionine, besides separated biomass is washed with water, and produced solution is combined with mentioned liquid phase. Produced methionine is crystallised out.
EFFECT: increased efficiency of methionine extraction.
