During the First World War many soldiers died due to bacterial infection.
Dr. Alexander Fleming was an army doctor at that time and was working on antibiotics in his laboratory. One day he found that there was some growth of fungi (mould) which was preventing the growth of the bacteria. He tested that fungi and found that it also killed other bacteria and that fungi were Penicillium notatum.
After this discovery fungi Penicillium notatum was used as antibiotic (substances that kill bacteria) namely penicillin to cure the infections of the soldiers with infected wounds due to bacteria.
Since, use of penicillin as antibiotic helped in curing the bacterial infections many deaths were prevented during First World War.
