A completely stirred tank reactor is used for growing penicillin according to a zero-order reaction. The input, glucose (CoH120%), is converted to various organic yeasts which eventually produce the penicillin. The flow to the system is 20 liters per minute (LPM) and the glucose conversion rate is 4 mg/(min L).
