Across
- 4. the growth of microorganisms in the blood
- 5. agents that prevent bacterial growth, make it stand still
- 7. good option for killing microbes in heat sensitive protein rich culture
- 9. hot air or open flame, can range from 160 to several thousand C
- 10. abbreviation for thermal death time; shortest amount of time to kill all microbes at specific temp
- 11. aka sanitization mechanically removes microbes; things like soap and detergents
- 13. hot water, boiling water, or steam between 60-135 C. Lower temps and shorter times than dry heat
- 14. removes all viable organisms including viruses and endospores; inanimate objects
- 15. machine used to kill bacteria on heat resistant materials
Down
