METHOD FOR PREPARING NUTRIENT MEDIUM FOR CULTIVATION OF YEAST XANTHOPHYLLOMYCES DENDRORHOUS (PHAFFIA RHODOZYMA) BASED ON SOYBEAN MELACE AND YEAST EXTRACT Russian patent published in 2022 - IPC C12N1/16 C12P23/00 A23K20/179 C12R1/785

Abstract RU 2785792 C1

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology, namely to the production of astaxanthin, and can be used in the microbiological industry. A method for preparing a nutrient medium for cultivating the yeast Xanthophyllomyces dendrorhous (Phaffia rhodozyma) is proposed. As components of the fermentation medium for cultivation, soy molasses is used in an amount that provides a total sugar content in the nutrient medium of 14–21 g/l, and residual brewer's yeast in an amount that provides a content of 2±0.2 g of yeast extract solids per liter of nutrient medium.

EFFECT: invention provides an increase in the amount of biomass by 34%, and the concentration of astaxanthin (g/l) - by 13%.
