Answer:
He concluded that Penicillium mold not only combat with the bacteria but this mold also had capability to combat infectious diseases. Then further testing revealed that the Penicillium notatum was creating a substance which can destroy bacteria. ... Penicillin was totally an accidental invention.Apr 30, 2015
Answer:
In 1922, Fleming discovered lysozyme, an enzyme with weak antibacterial properties that inhibited bacterial growth. He also found lysozyme in fingernails, hair, saliva, skin, and tears. In his research, Fleming found that lysozyme was effective against only a small number of non-harmful bacteria.
In 1928, he started to research common staphylococcal bacteria. An uncovered Petri dish near an open window became contaminated with mold. Fleming realized that the bacteria near the mold were dying. He isolated the mold and identified it as Penicillium genus, which he found to be effective against all Gram-positive pathogens. Gram-positive pathogens cause diseases, such as diphtheria, gonorrhea, meningitis, pneumonia, and scarlet fever. Fleming discovered that it was not the mold itself but a “juice” it had produced that had destroyed the bacteria. He named this “mold juice” penicillin.
Later, Fleming said: “When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I suppose that was exactly what I did.”
Initially, the medical community was not so enthusiastic about Fleming’s penicillin discovery. He also had difficulty isolating large quantities of “mold juice.” In 1940, just as Fleming was about to retire, 2 fellow scientists, Ernst Chain and Howard Florey, became interested in penicillin. Soon, they were able to mass produce penicillin for use during World War II.
