Answer:

Alexander Fleming discovered the antibiotic penicillin.

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.
