Objectives:

4. List the two general mechanisms that can be used to control microbial agents.

Actions of Microbial Control Agents

Alterations of Membrane Permeability

The susceptibility of the plasma membrane is due to its lipid and protein components.

Certain chemical control agents damage the plasma membrane by altering its permeability.

Damage to Proteins and Nucleic Acids

Some microbial control agents damage cellular proteins by breaking hydrogen bonds and covalent bonds.

Other agents interfere with DNA and RNA replication and protein synthesis.
