Concept explainers
To account: The microbistatic effect produced by low temperature as compared with the microbicidal effect produced by high temperatures.
Introduction: Microorganism can survive and reproduce within particular environments. Factors that influence the growth of microbes are pH, temperature, osmotic pressure, dissolved gases, and availability of water.
Explanation of Solution
Chemical and physical agents control microorganism growth. The physical agents include exposure of microorganism to low or high temperature. The enzymatic activity is inactivated by the appropriate low temperature. It produces microbistatic effect and it is reversible. The exposure of microbes to high temperature will destroy or deactivate or irreversibly denature the cellular enzymes. Thus, it will lead to microbicidal effects and result in the death of the cell.
