Ch 6

2. cold-loving below 15C cannot grow above 20C thrives in the refrigerator, rarely pathogenic
6. organism that must obtain carbon from organic molecules like glucose eg: E.coli
9. use co2 as a carbon source and able to synthesize their own organic "food." inorganic molecules (no carbon) such as iron, sulfur or magnesium provide the energy to make their "food"
10. both carbon and energy from organic compounds. process molecules through cellular respiration or fermentation. ie. S.aureus and Humans
12. organism that gets carbon from CO2 and can make its own "food"
13. grow at temperatures greater than 45C like volcanoes. Extreme ones grow between 80C and 121C
14. organisms feed on organic material from dead organisms. recycle organic nutrients in the environment ie. Pseudomonas, Clostridium, Bacillus, Micrococcus bacteria species and fungi
15. passive transport molecules move from an area of high concentration to low concentration

1. grow slowly in the cold, optimum temp of 15C and 30C ie S.aureus and Listeria monocytogenes
3. majority of medically significant microorganisms grow between 20C and 40C ie E.Coli
4. Obligate ones unable to grow outside of living host ie Mycobacterium leprae (leprosy) and Treponema pallidum (syphilis)
5. grow in high CO2 amount
7. photosynthetic (use light energy) and contain chlorophyll. produce organic molecules like sugar using CO2
8. diffusion of water through a selectively permeable membrane - more water to less water
11. can survive high temperatures, heat resistant endospore formers ie Bacillus and Clostridium
