Sample of penicillin mould presented by Alexander Fleming to Douglas Macleod in 1935. The discovery of penicillin was one of the most important scientific discoveries in the history of medicine. Ancient societies used moulds to treat infections and in the following centuries many people observed the inhibition of bacterial growth by moulds.
Penicillin was produced there in 300-litre batches, and Öppinger developed a rotating drum for a deep-tank fermentation process. [133] [135] Research was also carried out by Schering in Berlin using a sample of Fleming's mould, which they failed to cultivate; their efforts to determine the chemical structure of penicillin were also ...

Since the discovery of the beta-lactam antibiotic penicillin, the rates of antimicrobial resistance have increased. [38] Over time, methods for testing the sensitivity of bacteria to antibiotics have developed and changed. [25] Alexander Fleming in the 1920s developed the first method of
The term "penicillin" is defined as the natural product of Penicillium mould with antimicrobial activity. [8] It was coined by Alexander Fleming on 7 March 1929 when he discovered the antibacterial property of Penicillium rubens. [9]

Penicillium rubens is a species of fungus in the genus Penicillium and was the first species known to produce the antibiotic penicillin. It was first described by Philibert Melchior Joseph Ehi Biourge in 1923. For the discovery of penicillin from this species Alexander Fleming shared the Nobel Prize in Physiology or Medicine in 1945.

Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
