What did Alexander Fleming discover because of studying bacteria?
He actually discovered the antibiotic penicillin. Which test are you on? Do you need help with other answers>?
Just letting you know- I'm, Pro-Truth-Efficient
and I'm going to announce this until the end of the week -_-
I changed my name. -:
I'm good. That was the only question I was stuck on. I got a 97% Thx! And thx to "DrBob222" too. Byr.
Alexander Fleming discovered penicillin while studying bacteria.
To understand how Fleming made this discovery, we need to go through the steps he took:
1. Fleming was a bacteriologist at St. Mary's Hospital in London, and he was studying Staphylococcus bacteria. At the time, bacterial infections were a significant problem, and treatments were limited.
2. In 1928, while Fleming was working with a culture of Staphylococcus bacteria, he noticed something unusual. One of his bacterial cultures had been contaminated with a mold called Penicillium notatum.
3. Fleming observed that the bacteria around the mold were not growing, and there seemed to be a clear area of inhibition around the mold. This led him to hypothesize that something produced by the mold was killing the bacteria.
4. Fleming isolated the substance from the mold and named it "penicillin." He conducted experiments that showed the antimicrobial properties of penicillin, including its effectiveness against various bacteria.
5. However, it is important to note that while Fleming discovered penicillin's antibiotic properties, he did not pursue its development as a drug. It was only later, in the 1930s and 1940s, that other researchers like Howard Florey and Ernst Chain further developed penicillin into the world's first antibiotic.
So, to summarize, Alexander Fleming discovered penicillin while studying bacteria by observing the inhibitory effect of a mold called Penicillium notatum on bacterial growth.
