Study Notes
Sterilization Procedures
- Autoclaving: a method that uses high-pressure steam to kill microorganisms
- Dry heat sterilization: a method that uses hot air to kill microorganisms
- Filtration: a method that uses a physical barrier to remove microorganisms from a solution
- Chemical methods:
- Glutaraldehyde: a chemical disinfectant that kills microorganisms
- Ethylene oxide: a chemical sterilant that is used to sterilize heat-sensitive materials
Mechanisms of Action of Microbial Control Agents
- Damage to the cell wall: microorganisms are killed by disrupting the structure and function of their cell walls
- Alteration of cell membrane permeability: microorganisms are killed by changing the permeability of their cell membranes, preventing them from functioning properly
- Damage to proteins and nucleic acids: microorganisms are killed by damaging their proteins and nucleic acids, preventing them from carrying out essential cellular functions
