Industrial production of β-lactam antibiotics

The fermentation production of penicillin-G or -V is a fed-batch process carried out aseptically in stainless steel tank reactors of 30,000–100,000 gallon capacity. The fermentation usually involves two to three initial seed growth phases followed by a fermentation production phase having a time cycle ranging from 120 to 200 h.

Production of Penicillin

Production of penicillin began in the United States (1941) by surface culture fermentation of Penicillium notatum. During World War II, penicillin producing fungi were studied extensively to increase yields of penicillin. Now a day, penicillin is produced from Penicillium chrysogenum by submerged culture techniques. Morphology of Penicillum species is shown in Fig. 5.1.
