The discovery of penicillin, the first widely used antibiotic, is credited to which scientist?

Explanation

The discovery of penicillin is credited to Scottish scientist Alexander Fleming, who in 1928 noticed that a mold accidentally contaminating one of his bacterial culture plates was inhibiting bacterial growth around it. This observation eventually led to the development of penicillin as the first widely used antibiotic, revolutionizing the treatment of bacterial infections and saving countless lives, particularly from the 1940s onward. Fleming shared the 1945 Nobel Prize in Physiology or Medicine for this discovery. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
