The previous findings that activated sludge bulking was stimulated by 80 mg/l of lactic acid, acetic acid, and glucose, and that the lactic acid consumption rate increased in the bulking activated sludge, led to an idea that added glucose would be immediately converted to these organic acids in the aeration tank. As the result, therefore, no organic acid was detected upon the addition of 80 mg/l of glucose, but the activated sludge was bulked severely. When 160 mg/l of glucose was provided to the sludge continuously, a small amount of lactic acid was detected in the aeration tank. Acetic, propionic, butyric, and lactic acid were accumulatted and the sludge bulking occurred after articifial wastewater was given which contained 500 mg/l of glucose.The activated sludge bacteria produced lactic acid without a lag when they were incuvated with 80 mg/l of glucose under limiting oxygen.
