Discovery of Penicillin

Source: google.com Once Alexander Fleming forgot to clean the dish on which he was growing bacteria, and he went on a holiday. When he came back, then he discovered a mould growing in the dish. The mould that was surrounded by the bacteria has all been killed! Thus, he discovered that the mould has the power to destroy the bacteria and named it Penicillin. With more experiments, he was able to discover that it could destroy any other germs that caused infections. This discovery helped in saving lives of soldiers during World War II and led to a discovery of many new antibiotics. It was a revolution that led to mass production of penicillin so as to treat soldiers and people worldwide.
