Fleming’s first great discovery in November 1921 largely contributed to the research and knowledge to the humane immune system. Whilst having a cold Fleming accidently dripped mucus onto a culture of bacteria, thus leading to his discovery of Lysozyme. Thinking that his mucus might have some kind of effect on bacterial growth, he mixed it with the culture. A few weeks later, he observed that the bacteria had been dissolved.

In September 1928, Fleming, noticed that a culture of Staphylococcus aureus he had left out had become contaminated with a mold (later named penicillin), he also discovered that the colonies of staphylococci surrounding this mold had been destroyed.
Fleming thought that he had discovered an enzyme even more powerful than Lysozyme. Wanting to
Fleming decided to investigate further. He later discovered that it wasn’t an enzyme but actually an antibiotic. Enlisting the helping of two other researchers tried to stabilize and refine the
