Question: What impact had the discovery of penicillin to the world?
Answer: Penicillin has saved millions of lives by stopping the growth of the bacteria that are responsible for poisoning the blood and causing many other once fatal diseases.
Question: How did he discover penicillin?
Answer: Fleming, being a bacteriologist, was searching for cures to treat bacterial infections. One day in 1928 he discovered that bacteria he had been growing on a culture plate had been killed in an area close to where a mould was accidentally growing. He isolated the mould and showed that it released a substance that inhibited bacterial growth. He named the substance penicillin after the name of the mould. Fleming reported his ground-breaking results in the scientific paper “On the antibacterial action of cultures of a Penicillium with special reference to their use in the isolation of B. influenzae” published in British Journal of Experimental Pathology 10, 226-236 (1929).
Question: How did he come up with the name penicillin?
Answer: Fleming identified the mould that had contaminated his culture plates as being from the Penicillium genus, and therefore named the substance it released penicillin.
