Physical and chemical agents can be used to control microorganisms. 

Here are some physical and chemical agents used to control microorganisms:
Sterilization: A physical and chemical method that removes all microorganisms and bacteria, including spores. Sterilization is used to decontaminate medicine, food, and surgical instruments.
Disinfectants: Chemical agents that control the growth of microorganisms. Disinfectants differ from other chemicals in that they don't necessarily kill the spores of the microorganisms.
Antibiotics: Chemical agents that kill or inhibit the growth of certain types of microorganisms. Antibiotics are the most commonly used chemical agents for controlling microbial growth.
Antiseptics: Chemical substances that kill microorganisms that cause infections. Antiseptics and disinfectants act by destroying the integrity of the cell membranes of microorganisms.
Filtration: A physical method that relies upon pore size to eliminate unwanted substances and microorganisms. Liquids and other substances are poured through a filter with different pore sizes to help disinfect liquids and other materials.
Heat: One of the most common forms of microbial control. Heat can kill microbes by altering their membranes and denaturing proteins.
Membrane filters: Physical barriers that remove solids, viruses, bacteria, and other unwanted molecules.
Radiation: Used to control microorganisms when food or other materials are subjected to gamma rays or X rays. The radiations change the chemical composition of microorganisms by forming ions in the organic materials of the cytoplasm.
