      Is this a test question? 😛

      Alexander Fleming discovered penicillin the antibiotic. Apparently he accidentally sneezed onto a petri dish and some of the fungi grew big clear circles around themselves by killing off nearby bacteria. He looked at what the fungi was producing and that was penicillium.
