Microbial Control Methods

The Microbial Control Method refers to those methods which are used to prevent
or inhibit the growth of microbes.

The goal of these methods is to destroy pathogens and prevent their transmission
and to reduce or eliminate microorganisms responsible for the contamination

Sterilization is defined as the process where all the living microorganisms,

including bacterial spores are killed. Sterilization can be achieved by physical,

chemical and mechanical means.

• Chemicals used as sterilizing agents are called chemisterilants.

Disinfection is the process of elimination of most pathogenic microorganisms

(excluding bacterial spores) on inanimate objects. Disinfection can be achieved by

physical or chemical methods. Chemicals used in disinfection are called

disinfectants.
