Study Notes
Sterility and Sterilization
- Sterility is a relative term, indicating that an item may be free from viable microorganisms under specific conditions.
- Sterilization is essential in various industries, including the computer and space industries, to prevent contamination and ensure operational integrity.
Sterilization Methods
- Sterilization encompasses both physical and chemical methods, which are utilized to eliminate all forms of microbial life.
- Common physical methods include heat, radiation, and filtration, while chemical methods may involve gases, liquids, or other substances.
Microbial Death Kinetics
- The kinetics of microbial death can produce survivor curves, typically characterized by a logarithmic decline in the number of viable organisms.
- Irregular tailing on survivor curves indicates that not all microorganisms die at the same rate, challenging the assumption of uniform death.
Thermal Death Point
- The thermal death point refers to the highest temperature at which all microorganisms are killed in a specified time frame, not the shortest time required for complete sterilization.
