Abstract
The effect of lignocellulosic hydrolysate of crushed corn mobs on the growth and lactic acid formation in a continuous culture of Lactobacil lus casei and L. lactis at dilution rate 0.08-0.3/h was studied. A sim ple physiological model of the process was derived from computer-aided analysis of the data which relates bacterial growth, lactic acid form ation to the utilization of two different sources of nutrients. The pa rameters of the model were estimated by nonlinear regression and used for process simulation and estimation of maximum productivity of lacti c acid.
