Can you say that the microbial composition changes over time in each of the body locations? Give two pieces of evidence. Why do you think the scientists also tested the soil around the cadaver? The study was done with mice and their cadavers decomposed on soil graves in the University of Colorado Transgenic Facility. Do you think the graphs would have looked different if the decomposition events would have happened outside during the hot summer months? Explain.
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.
