Chapter 11, Problem 4MCQ
Summary Introduction
Introduction:
Methods of controlling microbial growth are divided into two categories: physical method and the chemical control method. Microorganisms can adapt to severe physical conditions like light, temperature, pressure, and moisture. Physical control agents use these factors to control the bacterial growth. Heat is the most prominent physical method of control.
