You take two stainless steel pins and place each in a separate pan of boiling water for 15 minutes. Using sterile forceps, you then remove each pin from the boiling water and place each separately in a tube of sterile nutrient broth. You put the two tubes of broth in a 35-degree Celsius icubator for two days and then observe them for miucrobial growth. In one you observe extensive growth as evidenced by heavy turbidity, but the other tube remains completely clear, indicating that no growth occurred. Explain.

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.
