Abstract Growth of cultures of Lactobacillus casei ATCC 7469 without pH control under aerobic conditions resulted in very low maximum specific growth rates (0.19 hr-1), exponential glucose utilization rates (0.10 log units/hr/ml of culture) and exponential lactate production rates (0.17 log units/hr/ml of culture), compared to anaerobic cultures. In anaerobic cultures glucose was converted stoichiometrically to lactate but in aerobic cultures this was never observed. It was found that aeration affects both the rate at which glucose is converted to lactate and the stoichiometry of this conversion. The investigation of a number of glucose-metabolizing enzymes suggests that an oxidative pathway for glucose breakdown becomes operative under aerated conditions.
