Abstract: A large amount of whey is discharged from sweet meat industry, which is responsible for environmental pollution and a large amount 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: 420C, 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%.

Keywords: Lactic acid, whey, Lactobacillus delbruki
