What did Alexandra Fleming discover and how?
His name was Alexander, not Alexandra . . . he accidentally discovered that a type of fungus would kill bacteria when he accidentally got a bit of bread mold on a culture dish that had a good growth of bacteria on it. The mold killed the bacteria! When this type of fungus was refined, it became the active ingredient of the antibiotic, "Penicillin".
Why was Alexander Fleming so important?
Alexander Fleming was a doctor and bacteriologist who discovered penicillin, receiving the Nobel Prize in 1945.Penicillin was the first antibiotic we ever had. His discovery was accidental but he was able to see the process behind it. He noticed that, on a plate used in Microbiology labs, that there was mold that wasn't supposed to be there. He also noticed that there was space around the mold and the bacteria growing there. The mold was making something that prevented the bacteria from growing any closer.When he studied that clear area, a product made by the mold was what prevented the bacteria from growing. The mold was Penicillin notatum. The product was called penicillin.

What are antibiotics and how were they first discovered?
Antibiotics are an amalgam of substances derived from microorganisms to control the growth of or kill off bacteria. Most credit Alexander Fleming for the discovery of penicillin and its many uses. Joseph Lister is also considered one of the forerunners in this field.Fleming discovered lysozyme (an antiseptic enzyme that occurs in tissue and secretions such as mucus and tears) in 1921 during his military career. In 1927, he discovered penicillin. The next year while experimenting with the influenza virus he found that a certain strand of penicillin, Penicillium notatum, completely destroyed staphylococcus bacteria in a culture plate. The mold created a "germ-free barrier," if you will, that prevented the staphylococcus from growing. Fleming found that this discovery was effective even when diluted to 800 times.And that's how penicillin was "born."
