Control of Microbial Growth

It can be defined as the process to inhibit or prevent the growth of the population of microorganisms. It usually involves the use of physical and chemical agents to the growth of microorganisms. It is very important to control the growth of microorganisms, especially in the pharmaceutical and biotechnology industries, academic research, medical field, and food industry.

Sterilization

It is a method for the destruction of all forms of vegetative growth and endospores from a medium. In other words, sterilization can be defined as a method of killing every microbial organism such as bacteria, fungi, etc. present in an object or a medium. There are different strategies present to sterilize an object, like physical methods and chemical methods of microbial control.
