Alexander Fleming discovered the antibiotic penicillin.
The antibiotic penicillin is from Penicillium notatum or P chrysogenum. Penicillin was developed in the following ways:
- The penicillium mould produced the antibiotic penicillin naturally.
- These penicillin moulds were grown in the deep fermentation tanks by adding sugar and other required ingredients. These ingredients increased the growth of the penicillin.
- Then the penicillin molecule was separated from the mold.
- The last step involved the purification of antibiotic medicine.
