Fundamentals Of Microbiology 10th Edition by Jeffrey Pommerville

Exercise 22

As a microbiologist in the 1940s, you are interested in discovering new antibiotics that will kill bacterial pathogens.

Drawing on the culture techniques of Robert Koch, design an experiment that would allow you to determine the killing properties of the sample substance.
