Who discovered penicillin?

• A. Louis Pasteur
• B. Marie Curie
• C. Jonas Salk
• D. Alexander Fleming from Penicillium mould

Answer: (D)

Penicillin was discovered when Alexander Fleming noticed that a mold called Penicillium had contaminated a Staphylococcus culture and, around the mold, bacterial growth stopped. He realized the mold released a substance that killed or inhibited bacteria, naming it penicillin. This observation revealed that a fungus could produce a chemical capable of treating bacterial infections, which led to the development of antibiotic therapy that transformed medicine. Fleming’s finding was later developed into a usable drug by others for mass production, but the initial breakthrough came from Fleming’s observation of Penicillium’s effect on bacteria. While Pasteur, Curie, and Salk are landmark figures in science, they did not discover penicillin.
