Question

explain the discovery of penicillin​

Answer 1

Answer:

In 1928, at St. Mary's Hospital, London, Alexander Fleming discovered penicillin. This discovery led to the introduction of antibiotics that greatly reduced the number of deaths from infection.

Explanation:

Alexander Fleming, a professor of bacteriology in London, is credited with discovering penicillin in 1928. Returning from vacation, he started cleaning up his messy lab and noticed that some petri dishes containing Staphylococcus bacteria had been contaminated with a mold, Penicillium notatum, which was preventing the normal growth of the bacteria, according to Dr. Howard Markel's column for PBS NewsHour. Fleming obtained an extract from the mold, named its active agent "penicillin" and determined that the extract killed many types of harmful bacteria.

"When I woke up just after dawn on September 28, 1928, I certainly didn't plan to revolutionize all medicine by discovering the world's first antibiotic, or bacteria killer. But I guess that was exactly what I did," Fleming later wrote about his discovery.
