Moist Heat
Dry Heat
process of destruction of all forms of microbial life
STERILIZATION
lowest temperature at which all organisms in particular liquid suspension will be killed in 10 minutes
THERMAL DEATH POINT
minimal length of time for all bacteria in particular liquid culture to be killed at a given temperature.
THERMAL DEATH TIME
time in which 90% of bacterial population will be killed at a given temperature
DECIMAL REDUCTION TIME
kills microorganisms by oxidation effects
Dry Heat
mode of action: burning contaminants into ashes
direct flaming
used for inoculating loops/needles
direct flaming
most common method of treating infectious waste
incineration
burning materials to ashes at temperatures 890°C-980°C
