PENICILLIN (David García)

In my opinion the Penicillin is the best invent of the world, because this help people all time. Penicillin was discovered by Alexander Fleming. This was the first antibiotic used in medicine. The person who discover the penicillin told the story of his discovery. Penicillin was discovered by Alexander Fleming.  The exact date was September 15, 1928. He was studying bacterial cultures. He was studying Staphylococo but accidentally forgot a sample near the window. Fortunately, he didn´t throw the sample.

The window where was the sample, was open. In this one there was humidity but also something had killed the bacteria. What he called Penicillin fungus; it was capable of killing deadly bacteria. Fleming won the Nobel Prize with other scientists for the discovery of penicillin. Penicillin is a medicinestar.
