Study Notes
Methods of Microbial Growth Control
- Sterilization: destruction of all forms of microbial life, with attention to bacterial spores
- Disinfection: destruction of pathogenic organisms on inanimate objects, such as table-tops
- Antisepsis: destruction of pathogenic organisms on living objects, such as skin surface
- Sanitization: reduction of pathogens to a level deemed safe by public health guidelines
- Degerming: physical removal of microorganisms using soaps or detergents
Types of Germicides
- Germicide: any chemical agent that kills microorganisms
- Bactericide: agent that destroys bacteria
- Fungicide: agent that kills fungi
- Viricide: agent that kills viruses
Effects of Conditions on Germicides
- Temperature: germicides are more effective at high temperatures, as they break down at lower temperatures
- Type of microorganism: affects the use of germicides
- Environment: affects the use of germicides
Learn about various methods for controlling microbial growth, such as sterilization, disinfection, antisepsis, sanitization, and degerming. Understand the differences between these methods and when to use each one.
