|
Sterilization |
A process that destroys all viable microbes, including viruses and endospores. |
|
|
Disinfection |
A process to destroy vegetative pathogens, not endospores; inanimate objects. |
|
|
Antiseptic |
Disinfectants applied directly to exposed body surfaces. |
|
|
Sanitization |
Any cleansing technique that mechanically removes microbes. |
|
|
Pasteurization |
Heat is applied to kill potential agents of infection and spoilage bacteria without destroying the food flavor or value. |
|
|
LTLT |
Low temperature, long time; 65 C for 30 seconds (batch method). |
|
|
HTST |
High temperature, short time; 70 C for 15 seconds (flash method). |
|
|
Lyophilization |
Freeze dying; preservation. |
|
|
Tyndallization |
Intermittent sterilization for substances that cannot withstand autoclaving. |
|
|
Autoclave |
Sterilization by steam at 120 C. And 20 psi for 20 minutes. |
|
|
Ionizing Radiation |
Deep penetrating power that causes electrons to leave their orbit, breaks DNA. |
|
|
Non ionizing Radiation |
Little penetrating power - item must be directly exposed. |
|
|
Thermal Death Time |
Shortest length of time required to kill all test microbes at a specified. |
|
|
Thermal Death Point |
Lowest temperature required to kill all microbes in a sample in 10 minutes. |
|
|
Microbiostatic / bacteriostatic |
Slows the growth of microbes / bacteria. |
|
|
Microbiocidal / bacteriocidal |
Kills microbes / bacteria. |
|
|
Antibiotics |
Are common metabolic products of aerobic spore-forming bacteria and fungi. |
|
|
Antimicrobials |
Are produced naturally or synthetically. |
|
|
Narrow spectrum |
Effective on a small range of microbes target cell components specific to some pathogens only. |
|
|
Broad spectrum |
Greatest range of activity target cell components common to most pathogens. |
