Continuous fermentation with cell recycling to produce lactic acid using E. mundtii QU 25 with a combination of cellobiose and xylose. The designed feeding sugar combination was cellobiose 50 g L−1 and xylose 30 g L−1. The reactor started with batch mode and then transferred to continuous mode after achieving steady state. The cells were concentrated before transfer. The color-coded curves show the simulation results and the points show the averages of three measurements
