Detailed explanation-1: -Sir Alexander Fleming Fleming, a trained bacteriologist, was working St. Mary’s Hospital in London when in 1928, he observed a plate culture of Staphylococcus that had been contaminated by a blue-green mold.

Detailed explanation-2: -This phenomenon has long been known; it may explain why the ancient Egyptians had the practice of applying a poultice of moldy bread to infected wounds. But it was not until 1928 that penicillin, the first true antibiotic, was discovered by Alexander Fleming, Professor of Bacteriology at St. Mary’s Hospital in London.

Detailed explanation-3: -He named the ‘mould juice’ penicillin. Later, he would say: “When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I suppose that was exactly what I did.”

Detailed explanation-4: -In 1928, Alexander Fleming discovered the green mould he was working with produced a substance that could kill many common bacteria that infect humans. He called this new, exciting substance “mould juice". After a couple of months it would be renamed ‘penicillin’.
