Inventions: Penicillin

alexander Fleming, in full Sir Alexander Fleming, (born August 6, 1881, Lochfield Farm, Darvel, Ayrshire, Scotland-died March 11, 1955, London, England), Scottish bacteriologist best known for his discovery of penicillin. Fleming had a genius for technical ingenuity and original observation.alexander fleming's mother's name is Grace Stirling Morton An uncovered Petri dish near an open window became contaminated with mold. Fleming realized that the bacteria near the mold were dying. ... 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.Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall (Figure 8). When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.How do penicillin antibiotics work? Penicillin antibiotics stop bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect the bacteria from their environment, and to keep the contents of the bacterial cell together.Penicillin antibiotics were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today, though many types of bacteria have developed resistance following extensive use.Antibiotics cannot kill viruses or help you feel better when you have a virus. Bacteria cause: Most ear infections. Some sinus infections.
