Explain. 5) ts it possible for a medium to be both differential and selective at the same time? Explain. (4 points) A picture of the plate is below: 6) With which technique was the plate inoculated with bacteria (disregard the arrow in the picture)?

Explanation / Answer

4. A complex medium is also known as chemically undefined medium, that is the ingredients in an undefined medium has many sources such as carbon, nitrogen, amino acids and so on. The composition of chemicals present in each source cannot be predicted. In turn, a defined medium also known as synthetic medium always has a chemically known composition of sources. Therefore a defined medium will not be a complex medium at the same time.
