Learn about the discovery of Penicillin with iMinds insightful knowledge series.

When Alexander Fleming discovered penicillin in 1928, it was a lucky accident. He didn't realize at the time that penicillin would dramatically change the face of medicine and the pharmaceutical industry.

Fleming was a researcher studying the natural antibacterial substances produced by the body. He had been working with the bacteria that caused boils. To study the bacteria he grew colonies of it on plates. He later took a holiday leaving plates of bacteria to grow while he was away. On returning from his holiday, he noticed a mould growing on one of the plates. Colonies of the bacteria, which should have been growing around the mould, had died off.
