1. Decimal Reduction time is a measurement of a. How long it takes for a given treatment to kill 100% of a microbial population. b. How long it takes for a given treatment to kill 90% of a microbial population. c. What percentage of a microbial population is removed during a given antimicrobial treatment. d. How long it takes to inhibit the growth of 99% of a population. e. How long it takes for a given treatment to kill 10% of a microbial population.
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.
