antisepsis
practice of using substances to control the growth of microbes on living skin
autoclave
machine that uses steam under very high pressure to sterilize surfaces and fluids
bactericide
substance that kills bacteria
bacteriostatic
causing microbial replication to fail inhibiting the growth of bacteria
decontamination
removal of harmful physical, chemical, or biological agents from an object, surface or fluid
desiccation
removal of water from a material
disinfection
destruction of 99.99% to 99.999% of all pathogenic microbes and other microorganisms, but not necessarily their spores and endospores, from a surface, object, or liquid
endospore
toughened, condensed form of cell that can withstand harsh environmental conditions and is formed completely within the bacterial cell and is released when the cell dies
filtration
passing liquid through a solid porous device that allows some but not all material to pass through
fungicide
substance that kills fungi
fungistatic
inhibiting the growth of fungi
germicide
substance that kills microbes
lyophilization
desiccation of material while frozen
microbiostatic
inhibiting the growth of a microbe but not killing it
pasteurization
process of heating liquids in the absence of oxygen to kill microbes that often make people sick or spoil liquids such as milk
phenol coefficient
agent's ability to kill microbes as compared to phenol
sanitization
type of disinfection that reduces levels of microbial pathogens (often especially in food and water) to amounts deemed safe by public health agencies
sterilization
statistically complete (99.9999%) destruction of all microbes, their spores, and endospores from a surface, object or fluid.
surfactant
chemical agent that reduces surface tension
thermal death point
temperature at which all target microbes in a culture are killed in a given time frame
thermal death time
time required to completely kill a specific target microbe in a specific culture at a specific temperature
