Differential

Explanation:

According to my research on studies conducted by various microbiologists, I can say that based on the information provided within the question the medium being used is called a Differential Medium. This is a bacterial growth media that contains specific ingredients in order to allow the scientists to visually observe and tell the different bacteria apart. Which is how the microbiologist differentiated the bacteria in this situation.
