Sir Alexander Fleming
Alexander Fleming discovered a penicillin accidentally. After working with Staphylococcus germs, he found a type of fungus that has bactericidal power. The name of the fungus is ‘Penicillium notatam’. Fleming was a doctor and microbiologist in Scotland. Born on 6 August 1881 in a peasant family. He passed the Medical examination from St. Morris Hospital Medical School in 1906. Although he was a physician, he was more interested in microbialism.
So he has researched various aspects of germs throughout his life. In 1928, he discovered that the existence of penicillin survival of a particular type of fungus. Although Alexander Fleming invented penicillin for the first time, two scientists brought him to a human condition – Howard Florey (1898-1968) and Ernest Chain (1906-1979). In 1938, they completed the extraction and purification of the penicillin.
As a result, both of these scientists also received the Nobel Prize in Medicine in 1945 with Alexander Fleming. The discovery of penicillin was a new horizon for the medical world. Alexander Fleming received the Nobel Prize for his research, and further recognition and respect. Alexander Fleming is famous as an inventor of antibiotics.
Antibiotics are some of the biological chemicals that destroy or enhance microorganisms (especially bacteria). Generally, one antibiotic creates one kind of microbial and works against other microorganisms. Different bacteria and fungi make antibiotics. “Antibiotics” are commonly used against bacteria, do not work against the virus. However, antibiotics are the members of a large germicidal group, including various anti-viral (anti-viral), anti-fungal (fungal-destructive) etc. There are many germs in the genus, many of whom have not yet been tested as medicines, such as Bacteriocin – bacteria-killer protein toxin (poisons) that are bacterial by nature. In general, the term antibiotic refers to small organic chemicals. Fleming was elected Fellow of the Royal Society in 1943 and was awarded the knighthood in 1944. Sir Alexander Fleming died in London on 11 March 1955.
