Engineered bacteria are commonly used and cultured in pharmaceutical laboratories to produced drugs like insulin. However, during one instance, with the desire to increase the rate of insulin production, one scientist tried to modify the process and put another substance (chemical x) in the growth medium which is chemically almost the same to the substance (chemical x’) normally put in the medium. After which, the scientist found out that the amount of insulin produced in the medium decreases as compared to the normal production. Again, within the context of our discussion, explain the possible reason for the observed result.

Nutrient Growth Medium

It is a culture medium or nutrient broth for all kinds of microorganisms to grow properly and create their colony. This matrix provides support to increase the population of microbes through the method of cell proliferation. It is regarded as the food material for those organisms. It is a type of in vitro mechanism, in which the development of life is processed outside the host body. It can be solid, semi-solid, or liquid in nature. Different kinds of cells develop in different types of media.
