Who discovered Penicillin?
Explanation
Alexander Fleming is credited with the discovery of penicillin. In 1928, while working as a bacteriologist, Fleming accidentally discovered the mold spores of the Penicillium fungi on a contaminated petri dish, which displayed antimicrobial properties by inhibiting the growth of bacteria. This serendipitous observation laid the foundation for the development of the first antibiotic and revolutionized the field of medicine by providing an effective treatment for bacterial infections. Fleming's thorough investigations and subsequent findings paved the way for the mass production and widespread use of penicillin, ultimately saving countless lives and significantly advancing the field of medicine.
