Document Summary
Microbial growth (highlighted ones were on my test: distinguish between macronutrients and micronutrients. Micronutrients elements needed in very small amounts: give at least 6 examples of macronutrients, oxygen, carbon, nitrogen, hydrogen, phosphorous, sulfur, potassium, magnesium, calcium, sodium, give at least 4 examples of micronutrients. Growth factors are organic compounds (not elements) needed in very small amounts. In some cases, the organisms can make them, other times they are gained from the environment: name the 5 groups describing an organism"s relationship to oxygen. Facultative aerobe not required, but growth better with. Contains a reducing agent (thioglycolate), that reacts with oxygen to form water making the broth anoxic. Only oxic zone is at air-surface interface: you inoculate the following organisms into tubes containing thioglycolate broth. Enzymes made by cells can neutralize toxic forms of oxygen: catalase, peroxidase, superoxide dismutase, superoxide reductase, what enzyme combinations would detoxify superoxide (o2. Non-nitrogen fixers use inorganic compounds such as ammonia (nh3) and.
