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.
Glass phial of British Standard penicillin. The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first ...
The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington. The source of the fungal contaminant was established in 1966 as coming from La Touche's room, which was directly below Fleming's.
"It was an accident" is never a phrase that you want to hear in the laboratory -- well, almost never. After all, taking an experimental drug from the fume hood of a chemistry lab all the way to ...
Penicillin G (benzylpenicillin) was first produced from a penicillium fungus that occurs in nature. The strain of fungus used today for the manufacture of penicillin G was created by genetic engineering to improve the yield in the manufacturing process. None of the other natural penicillins (F, K, N, X, O, U1 or U6) are currently in clinical use.
Play-Doh was originally called Rainbow Modeling Compound and used to clean wallpaper. A NJ nursery school teacher found it was fun to use as a toy.
I only discovered it by accident." [ 1 ] Fleming's goal was to develop a cheap and effective drug that would be available to all the world. [ 2 ] Although Fleming did not initially have the means to bring penicillin into mass production, Andrew Moyer , who, unlike Fleming, did apply for a patent, was eventually was able to facilitate penicillin ...
The 1961 edition of Encyclopedia Britannica vol.9 p.371 Title: Fleming, Sir Alexander - states that his discovery of the antibacterial powers of the mold from which penicillin is derived was made in 1928 and was a "triumph of accident and shrewd observation."
