Learning objectives. understand and compare various physical methods of controlling microbial growth, including heating, refrigeration, freezing, high pressure treatment, desiccation, lyophilization, irradiation, and filtration. for thousands of years, humans have used various physical methods of microbial control for food preservation.
Physical Methods To Control Microbes Microbiology Notes Microorganisms are controlled by means of physical agents and chemical agents. physical agents include such methods of control as high or low temperature, desiccation, osmotic pressure, radiation, and filtration. control by chemical agents refers to the use of disinfectants, antiseptics, antibiotics, and chemotherapeutic antimicrobial chemicals. These bacteria are metabolically active, carrying out various cellular processes to support their growth and proliferation. vegetative bacteria are the predominant form found in most environments and are the focus of physical control methods discussed in the chapter on using physical methods to control microorganisms. Measuring microbial control. physical and chemical methods of microbial control that kill the targeted microorganism are identified by the suffix cide (or cidal). the prefix indicates the type of microbe or infectious agent killed by the treatment method: bactericide s kill bacteria, viricide s kill or inactivate viruses, and fungicide s kill. Measuring microbial control. physical and chemical methods of microbial control that kill the targeted microorganism are identified by the suffix cide (or cidal). the prefix indicates the type of microbe or infectious agent killed by the treatment method: bactericides kill bacteria, viricides kill or inactivate viruses, and fungicides kill.

Physical or chemical methods to control microbial growth that result in death of the microbe are indicated by the suffixes cide or cidal (e.g., as with bactericides, viricides, and fungicides), whereas those that inhibit microbial growth are indicated by the suffixes stat or static (e.g., bacteriostatic, fungistatic).
