Sir Alexander Fleming (1881-1955),Nobel laureate and discoverer of penicillin. Fleming studied medicine at St.Mary's,London,as a result of a small legacy. He made his famous discovery in 1928 whilst studying an enzyme called lysozyme. Fleming had left a culture dish of Staphylococci sp. uncovered and it became contaminated with an airbourne mould. He noticed that the bacteria were killed near the mould,which he called Penicillin notatum. Later,others isolated a chemical from this that was bactericidal and non-toxic,called penicillin. It was not until WW2 that large-scale production started,but Fleming became a folk hero,winning the 1945 Nobel Prize | |
