This answer is: A German company patented the drug, and ultimately, Domagk won a Nobel Prize in 1939. This research eventually led to the isolation of pure penicillin in 1940, after which the two continued to work on the scale up and purification of the antibiotic. Fleming was a Scottish physician (1981- 1955). Its here that we shift from invention to innovation and here we meet Howard Florey and Ernst Chain, who were to eventually share the Nobel prize in medicine with Fleming for the practical application and mass production of penicillin. Fleming saw hundreds of They were sure that, if Fleming was right, this discovery could save a lot of lives, prevent pain and make it much easier to fight infectious diseases and prevent other infections.

However, the purification and first clinical use of penicillin would take more than a decade. The strain that was eventually used in mass production was a third strain, P. chrysogenum, found in a moldy cantaloupe in a market, which produced 6 times more penicillin than Flemings strain.
