METHOD OF PREPARING NUTRIENT MEDIUM FOR GROWING OF EDIBLE MUSHROOMS Russian patent published in 1999 - IPC

FIELD: agriculture and biotechnology, in particular, artificial growing of edible mushrooms. SUBSTANCE: method involves mixing cereal crop straw and coniferous tree wastes, used in an amount of 35-60% and 40-65%, respectively; wetting mixture with low-concentration acetic acid solution for 2-3 hours; packing obtained mass in resilient air-tight thermally-stable bag and sterilizing under steam pressure of 150-200 MPa at temperature of 121-135 C for 60-90 min. In the process of sterilization, mixture is subjected to hydrolysis for increasing yield of sugar from raw material. Obtained medium provides optimum ratio of chemical substance for development of mycelium and growth of mushroom biomass. EFFECT: increased efficiency and improved quality of nutrient medium. 3 cl, 7 ex
