The effects of V1, V0 and K LR on the production of lactic acid and pH. The variations of lactic acid and pH in wild type are set as blank control. The curves indicated the simulated concentration of lactose and pH along with time under different values of V 1 , V 0 and K LR . A The effects of V 1 (10.5 h-1 or 21 h-1), where V 0 = 1 h-1, K LR = 564 h-1. B The effects of V 0 (0.1 h-1 or 1 h-1), where V 1 = 10.5 h-1, K LR = 564 h-1. C The effects of K LR (564 h-1 or 1128 h-1), where V 0 = 1 h-1, V 1 = 10.5 h-1
