Microorganism Controlling by Chemical Methods

Microorganism Controlling by Chemical Methods -

Chemical methods are expected to remove the pathogenic organisms from an object (or body).

These methods rarely achieve sterilization as in physical methods. The process of removal is called disinfection.

If the object is non living, the chemical is known as disinfectant. However, if the object is living, as a tissue of human body, then the chemical is an antiseptic.

Antiseptics and disinfectants may be either bactericidal or bacteriostatic.

The former agent kills the microbes whereas the latter temporarily prevents their further multiplication.

The effectiveness of a chemical agent is based on phenol coefficient (PC).

This number indicates the ability of a particular antiseptic or disinfectant as compared to phenol under identical conditions.

A PC higher than one indicates that the chemical is more effective than phenol.
