SACCHAROMYCES CEREVISIAE RD-1 STRAIN AND METHOD FOR ITS CULTIVATION

摘要

The strain and the method for its preparation are applicable in the food processing industry. They ensure maximum productivity and the high quality of the product: high lifting power, maltase activity and trehalosa content. The highly productive Saccharomyces cerevisiae RD-1 strain is isolated and cultivated through this method in the conditions of repeated fed-batch culture. The control of the concentration of the inhibiting substances during the dosing of the nutrient medium in the reactor is realised in 1-2 cycles. During each cycle, after removing part of the cultured medium, which is 25 per cent of the liquid phase, this quantity is substituted by adding 20-23 per cent of drinking water.
