What did Alexander Fleming discover?
Why did Fleming leave his nasopharyngeal mucus on a petri dish?
Why did Fleming entrust his cultures to a bath of antiseptic?
In 1921 he discovered a substance in nasal mucus that causes bacteria to disintegrate. Fleming and a colleague subsequently detected this substance, which he named lysozyme, in human blood serum, tears, saliva, milk, and a wide variety of other fluids.
6 days ago · In November 1921 Fleming discovered lysozyme, an enzyme present in body fluids such as saliva and tears that has a mild antiseptic effect. That was the first of his major discoveries. It came about when he had a cold and a drop of his nasal mucus fell onto a culture plate of bacteria. Realizing that his mucus might have an effect on bacterial ...
He also discovered the enzyme lysozyme from his nasal discharge in 1922, and along with it a bacterium he named Micrococcus lysodeikticus, later renamed Micrococcus luteus . Fleming was knighted for his scientific achievements in 1944. [8] . In 1999, he was named in Time magazine's list of the 100 Most Important People of the 20th century.

Mar 15, 2024 · In 1921, Fleming endured a cold and analyzed his own nasal mucus. He discovered a new bacteriolytic agent known as a lysozyme —an antibacterial enzyme found in many bodily fluids such as tears, saliva, and mucus. 9 Collaborating with other scientists, Fleming established that lysozymes were normal biological components of various bodily fluids.
Jan 1, 2004 · They determined that something had diffused from the nasal mucus to prevent the germs from growing near the mucus and, beyond that zone, to kill and dissolve bacteria already grown. 2, 3 As Fleming investigated this phenomenon, he found that freshly gathered mucus was even more potent and that the same lytic power could be demonstrated in tears ...
