FIELD: biotechnology.
SUBSTANCE: new lactic acid Lactobaccillus delbrueckii strain B-8744 strain as lactic acid producer is isolated from specific Lactobaccillus delbrueckii strain by selection of spontaneous mutations. In process of lactic acid fermentation with new strain on sugar-containing nutrient medium with sugar concentration of 12 % total productivity is 2.92-2.96 g/(l.h), and lactic acid yield is 93.9-95.2 %.
EFFECT: new genetically stable lactic acid Lactobaccillus delbrueckii strain of high productivity.
