The concentration of biomass and lactic acid were measured in the broth after 24 h of growth. Yx/s indicates g of dry biomass produced per g of substrate; Yp/s indicates g of lactic acid produced per g of substrate; μ8h indicates the specific growth rate in h−1 calculated in the first 8 h of growth. Values are an average of 3 different experiments with standard deviations ≤ 5%.
