D. Edward Jenner

Answer 1

Hint: Selman Waksman is known to discover over 20 antibiotics. Antibiotics help in treating and curing the bacterial infections. They are obtained from microorganisms.

Complete answer:
To solve the question we must know about antibiotics and their discovery. Antibiotics are substances which are obtained from microbes. They either kill bacteria or prevent them from reproducing inside the human body. They are considered to be antibacterial agents that prevent and cure any type of bacterial infections.
The term “antibiotic” was coined by an American microbiologist Selman Waksman. Selman Waksman is also credited with the discovery of Streptomycin. He was researching the decomposition of soil microorganisms when he discovered Streptomycin, an antibiotic which is used to cure tuberculosis. Moreover, he also invented the various techniques which further enabled the discoveries of many other antibiotics.

However, the first antibiotic was discovered by Alexander Fleming. He was working in his laboratory when he accidentally discovered Penicillin.

Note: Louis Pasteur was a French microbiologist who is known for the discovery of the principles of vaccination. He also invented a technique known as pasteurization to kill pathogens present in food. Edward Jenner discovered the world’s first vaccine, smallpox vaccine. He is also known as the “Father of Immunology”. Alexander Fleming also discovered the enzyme lysozyme. Selman Waksman also discovered Neomycin which is derived from Actinomycetes.
