PRODUCTION OF LACTIC ACID FROM SWEET MEAT INDUSTRY WASTE BY LACTOBACILLUS DELBRUKI

Abstract

A large amount of whey is discharged from sweet meat industry, which is responsible for environmental pollution and a large a mount of whey protein and milk sugar are also wasted. This whey may be utilized for valuable lactic acid production. Lactobacillus delbruki was used for lactic acid production from cow - milk whey. Lactic acid production was 12.22 gm/L at pH: 6.8, temperature: 42 0 C, Inculum volume: 4% , fermentation time: 24hr, medium volume: 125 mL in 250 mL Erlenmeyer flask, medium composition, whey supplemented with peptone : 1.5%, glucose: 2.0 % and ammonium chloride: 1.0%.
