Caption: Computer graphics space-filling representation of a molecule of penicillin, an antibiotic, a substance with bactericidal properties. The action of penicillin was first realised by Alexander Fleming in 1928 while he was working at St Mary's Hospital, London. Fleming observed that colonies of staphylococci bacteria had not grown around a blue mold that had accidentally contaminated his culture. The mold was Penicillium notatum, which he realized was secreting a substance lethal to the bacteria - penicillin. Fleming's observations were the basis of research done by Ernst Chain & Howard Florey that led to the commercial manufacture of penicillin by 1945.
