How do microbes differ in their response to oxygen levels? Why would they differ? What enzymes are needed to adapt to environments containing differing amounts of oxygen?
Compare and contrast the enzymes catalase, superoxide dismutase, and superoxide reductase from the following points of view: substrates, oxygen products, organisms containing them, and their role in oxygen tolerance of the cell.
Oxygen can be a friend or foe to aerobic or anaerobic microbes. what oxygen relationships to microorganisms and pay particular attention to growth, toxicity, and enzymes involved and what they do.
