Explanation:
The culture medium is a chemical preparation that has the necessary nutrients for microorganisms of a given biological sample to multiply, allowing its study, identification and analysis. The main components of a culture medium are sources of carbon, energy (sugars), nitrogen, phosphorus and minerals.
There are several types of culture medium, among them we can mention the differential culture medium, which is the type of medium that is being used in the experiment shown in the question above. The differential culture medium allows the distinction between various genera and species of similar microorganisms. This distinction is possible because this type of culture medium has substances that allow for a presumptive differentiation, evidenced by the color change or the morphology of the colonies.
