Please help with the following problem.
You inoculate tubes of thioglycollate agar with a species of bacteria. There is no oxygen available in the bottom on the tube, while there is exposure to atmospheric concentrations of oxygen (~20%) at the very top of the tube. Describe, or draw, where in the tube you would expect the following types of microorganisms to grow: aerotolerant anaerobe, microaerophile, strict anaerobe, obligate aerobe and facultative anaerobe. B) Describe the function of the catalase and superoxide dismutase (SOD) enzymes. Which of the types of microorganisms listed in part A are most likely to have both catalase and SOD enzymes, and which is most likely to lack both catalase and SOD enzymes?© BrainMass Inc. brainmass.com March 5, 2021, 12:25 am ad1c9bdddf
This picture illustrates the distribution quite well:
1) Obligate aerobes - needs oxygen, found clustered at top.
2) Obligate anaerobes - anaerobic, found clustered at bottom. This would be where strict anaerobes would be as ...
