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.

The fermentation Process Fermentation is the technique used for the commercial production of penicillin. It is a fed-batch process that is carried out aseptically in stainless steel tank reactors with a capacity of 30 to 100 thousand gallons. Various carbon sources have been adopted for this process – including glucose, sucrose and other ...

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.

Background Multi-copy gene integration into microbial genomes is a conventional tool for obtaining improved gene expression. For Penicillium chrysogenum, the fungal producer of the beta-lactam antibiotic penicillin, many production strains carry multiple copies of the penicillin biosynthesis gene cluster. This discovery led to the generally accepted view that high penicillin …
