It was first extracted from the fungus Penicillium. After further studies, he confirmed that the fungus growing there was Penicillium and its secretion had destroyed the bacterial colonies. So he isolated the mold, grew more of it, and then experimented to see how … It was first commercial antibiotic discovered from a fungus called Penicillium notatum.

He plated bacterial colonies on a medium in petri-plates for an experiment. Starting in the late 19th century there had been reports of the antibacterial properties of Penicillium mould, but scientists were unable to discern what process was causing the effect. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin. FALSE. He grew more of the mould, naming it penicillin from its Latin name Penicillium. The mould that changed the world: Alexander Fleming's original penicillin fungus is regrown by scientists who sequence its genome … When the patient recovered, the cure was the subject of a major article in The Times newspaper in Great Britain, which named Oxford as the source of the penicillin. The … Using similar discovery and production techniques, researchers discovered many other antibiotics in the 1940s and 1950s: streptomycin, chloramphenicol, erythromycin, vancomycin, and others. In 1928, Scottish scientist Alexander Fleming made history. Dr. Alexander Fleming accidentally discovered penicillin, when staphylococci bacteria in petri dishes in his laboratory – that had been left unattended over summer vacation – reacted with mold that had drifted up from a mycology lab downstairs, thus allowing him to observe that the mold was somehow inhibiting the growth of the bacteria.
