Figs. 1 and 2 present the time course of lactic acid production by LA 104 and ATCC 25600, respectively. Lactic acid production was investigated in batch fer-mentation at ratios of 1:2, 1:1.5, and 1:1 (fresh material:water) corresponding to 136.36, 168.22, and 219.51 g dried material L−1, respectively
