Penicillin Culture

On the back, the red ink inscription PENICILLIUM NOTATUM, ALEXANDER FLEMING. Penicillin, discovered occasionally in 1929 by the British bacteriologist Sir Alexander Fleming, is an antibiotic produced by a fungus called" "Penicillium crysogenum" ".
Fleming's discovery did not initially attract greater interest and there was no concern about using it for therapeutic purposes in cases of human infection until the outbreak of World War II in 1939. In 1940, Sir Howard Florey and Ernst Chain, of Oxford, they resumed Fleming's research and were able to produce penicillin for therapeutic purposes on an industrial scale, ushering in a new era for medicine - the era of antibiotics.
