What did Fleming discover?

Discovered penicillin, a miracle drug that cured various infectious diseases

In 1928, Fleming discovered penicillin, a remedy for infectious diseases. Fleming's discovery is considered the most important discovery in the history of medicine.

Penicillin quickly cured infectious diseases such as pneumonia and tetanus, which could not be cured by any drugs available at the time, and saved many lives.

Penicillin is now known as the "miracle drug.

(bacteriologist)

Penicillin was originally made from a fungus, the blue-green mold! Penicillin is made from the blue mold that grows on bread. Until then, no one had thought that mold could be used to treat infectious diseases. The discovery of penicillin led to the development of many medicines from molds.

Why did Fleming begin his research on bacteria?

Fleming's research into bacteria was triggered by the war. While treating soldiers in the war zone, Fleming saw soldiers suffering and dying from bacteria that entered their wounds, and he became inspired to create a medicine that would eliminate bacteria. After the war, Fleming focused his research on bacteria and finally discovered penicillin in 1928.
Penicillin was then developed as a medicine to treat diseases caused by bacteria.

Penicillin saved the life of a dear friend. With the discovery of penicillin, Fleming was also able to save the life of an important friend.
The friend was suffering from a bacterial disease and was told he had only a few days to live, but Fleming gave him a penicillin injection as his last hope.
The friend miraculously recovered. Fleming's joy must have been enormous.

Is it true that another person developed and successfully mass-produced penicillin?

To use penicillin to treatinfectious diseases, it needed to be produced in large quantities. However, Fleming was a bacteriologist and did not know how to do this. Research on bacteria and the development and production of drugs are two completely different things.
In 1940, 12 years after Fleming's discovery, two researchers named Flory and Chane began their research. In 1940, twelve years after Fleming's discovery, two researchers, Flory and Chane, finally succeeded in developing and mass-producing penicillin as a cure for infectious diseases. This saved many patients from infectious diseases.
This event is also known as the "rediscovery of penicillin.

All three of the discoverers of penicillin received Nobel Prizes. The mass production of penicillin helped many people and was very effective against various infectious diseases.
Fleming, who first discovered the miracle drug penicillin, and Florrie and Chane, who rediscovered it, were awarded the Nobel Prize in Physiology or Medicine in 1945 in recognition of their achievements.
