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
