Ch. 7 Control of Microbial Growth Flashcards
Sterilization
Removal or destruction of ALL living microbes(including endospores, naked viruses, other spores)
Disenfection
Reduce/destroy vegetative pathogens (not endospores)
Sanitization
Removal of microbes and exposure to disinfectant of an object/surface
Antisepsis
Removal/destruction of vegetative pathogens from living tissue (aseptic technique)
Degermation
Mechanical removal of microbes from living tissue
-cide
Kills
-static
Prevents growth, does not kill and if removed growth may resume
Thermal Death Point
Lowest temp at which all microbes in a liquid are killed in 10 min
Thermal Death Time
Minimal length of time for all bacteria in a liquid culture to be killed at a specific temp
Decimal Reduction Time
Time in minutes in which 90% of a population of bacteria at a given temp will be killed
