Across
  1. 5. HATE oxygen and die in its presence
  2. 7. cold loving microbes whose optimum temp is 15 degrees C or below
  3. 8. organism that must obtain carbon from organic molecules
  4. 10. contains carbon and hydrogen
  5. 13. derive carbon and energy from organic compounds
  6. 14. require a small amount of oxygen for metabolism
  7. 17. type of heterotroph that feeds on organic material from dead organisms
  8. 18. use C02 as carbon source, and instead of light use inorganic molecules to provide energy
  9. 19. microbes optimum temp greater than 45 degrees C, extreme between 80 and 121 C.
  10. 20. can survive short exposure to high temps, include heat resistant endospore formers
Down
  1. 1. use C02 as carbon source and light as energy
  2. 2. DON'T require oxygen for metabolism but can still use it, many gram-neg intestinal bacteria
  3. 3. organism that gets carbon from C02 and can make its own "food"
  4. 4. don't use oxygen but can survive and grow to some extent with it present
  5. 6. an organism that cannot grow without oxygen
  6. 9. microbes optimum temp between 15 and 30 degrees C
  7. 11. contains combos of atoms other than carbon and hydrogen
  8. 12. majority of medically significant microbes grow optimally at 20 to 40 degrees C
  9. 15. prefer high concentration of salt
  10. 16. grow best at higher C02 amounts than normally present in atmosphere
