Abstract: The biosynthesis of ammonium lactate, a product of lactic acid fermentation was studied from corn and glucose at five different pH values of 5.4 to 7% In the glucose fermentations, a 100 % conversion of substrate was obtained resulting in a maximum lactic acid production yield of 93-2 %. The optimum pH for the maximum volumetric rate of lactic acid biosynthesis (1.56 g dm-3 h-l) was between 6 0 and 65. The corn fermentations were slower than the glucose fermentations with a resulting lactic acid yield of 67.5…
