Способ получения рибонуклеиновой кислоты и очищенного дрожжевого экстракта относится к микробиологии и биотехнологии и может быть использован в пищевой, химической и медицинской промышленности. Способ заключается в том, что рибонуклеиновую кислоту и очищенный дрожжевой экстракт получают из дрожжей путем экстракции водой, взятых в соотношении 1:12-25, отделением биомассы, концентрированием рибонуклеиновой кислоты ультрафильтрацией на мембранах с границей разделения по мол.м. не более 15000 Д до содержания ее в концентрате не менее 25 г/л, осаждением рибонуклеиновой кислоты минеральной кислотой с последующей обработкой и сушкой. Способ позволяет повысить выход рибонуклеиновой кислоты до 6,4% от сухого вещества дрожжей при одновременном улучшении качества дрожжевого экстракта.The method of obtaining ribonucleic acid and purified yeast extract relates to microbiology and biotechnology and can be used in the food, chemical and medical industries. The method consists in that ribonucleic acid and purified yeast extract are obtained from yeast by extraction with water, taken in a ratio of 1: 12-25, separation of biomass, and concentration of ribonucleic acid by ultrafiltration on membranes with a separation line according to mol.m. no more than 15,000 D until its content in the concentrate is not less than 25 g / l, precipitation of ribonucleic acid with mineral acid, followed by treatment and drying. The method allows to increase the yield of ribonucleic acid to 6.4% of the dry matter of the yeast while improving the quality of the yeast extract.
