Across
- 2. doesn’t sterilize, asepsis; endospores, protozoa cysts can still live
- 4. kills all microbes (ex: autoclaving)
- 5. free of pathogenic contaminants
- 6. microbe growth in blood and other living tissues
- 8. freeze drying; used for long-term preservation
- 9. excites atoms by raising them to a higher energy state but does not ionize them; disinfecting surfaces; UV light is good; terrible at penetrating; affects structure of DNA; measured in nm when talking about UV rays as an example of this
- 12. kill
- 13. mechanical cleansing technique to reduce number of microbes to reduce contamination; meeting health standards
- 15. not sterile; heat; can live (batch, flash, UHT)
- 23. heat; not as effective as boiling
- 24. used on non-living surfaces; destroys most microbes
- 26. mechanical removal of most microbes from living and non-living surfaces
Down
- 1. degerming; good for heat-sensitive things
- 3. steam and pressure (sterilization)(121*C, 15 psi, 15 mins)
- 7. preservation; slows metabolism
- 10. still static mainly; slows down the ability to grow
- 11. removing number of microbes on human skin
- 14. only way to kill prions
- 16. practice of preventing microbial entry into sterile tissues
- 17. inhibits growth
- 18. electron radiation that ejects orbital electrons from an atom causing ions to form; good at killing, but not penetrating; measured in Grays
- 19. static; dries out cells
- 20. more effective than quick freezing
- 21. used in labs as a method of filtration
- 22. reduces number of microbes; not pathogenic; living surfaces
- 25. removing microbes from air and liquids with membranes with pore openings
