While working at St Mary's Hospital in London in 1928, Scottish physician Alexander Fleming was the first to experimentally demonstrate that a Penicillium mould secretes an antibacterial substance, which he named "penicillin". The mould was found to be a variant of Penicillium notatum (now called Penicillium rubens), a contaminant of a ...

Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. [6] Fleming's student Cecil George Paine was the first to successfully use penicillin to treat eye infection (neonatal conjunctivitis) in 1930.
It probably was due to the fact that the infection was with influenza bacillus (Haemophilus influenzae), the bacterium which he had found unsusceptible to penicillin. [32] Fleming gave some of his original penicillin samples to his colleague-surgeon Arthur Dickson Wright for clinical test in 1928.
Alexander Fleming’s discovery of penicillin in 1928 happened by chance. He left petri dishes out while on vacation, and mold contamination revealed the world’s first antibiotic.
The medicinal importance was discovered by Alexander Fleming, a physician at St Mary's Hospital, London. In September 1928, Fleming found that one of his bacterial cultures (of Staphylococcus aureus) was contaminated with mould, and that the area around the mould inhibited bacterial growth. He gave the name penicillin for the purported ...
A medallion containing some of the original mold involved in the discovery of penicillin is expected to fetch up to $50,000 at auction.
Penicillin, a drug produced by P. chrysogenum (formerly P. notatum), was accidentally discovered by Alexander Fleming in 1929, and found to inhibit the growth of Gram-positive bacteria (see beta-lactams). Its potential as an antibiotic was realized in the late 1930s, and Howard Florey and Ernst Chain purified and concentrated the compound.
