Here is a short story that tells you who discovered penicillin
Penicillin is a widely used antibiotic agent, derived from penicillium mould. Penicillin was discovered by bacteriologist Alexander Fleming at St Mary’s Hospital in London in 1928. He observed that a blue-green mould had contaminated a plate culture of Staphylococcus and the colonies of bacteria, adjacent to the mould, were being dissolved.
Dr. Fleming named the substance penicillin, and in 1929, published his discovery might have therapeutic value if it could be produced in quantity. It was not until 1939 that Dr. Howard Florey and three colleagues at Oxford University began intensive research, and were able to demonstrate penicillin’s ability to kill infectious bacteria.If you liked this post please buy me a cup of coffee to quench my thirst
