What is the difference between facultative anaerobes and aerotolerant anaerobes? Choose one: A. Aerotolerant anaerobes grow at the bottom of a thioglycolate tube, whereas facultative anaerobes will grow throughout. B. Facultative anaerobes grow at the bottom of a thioglycolate tube, whereas aerotolerant anaerobes will grow throughout. C. Aerotolerant anaerobes can both respire and ferment, whereas facultative anaerobes only ferment. D. Facultative anaerobes can both respire and ferment, whereas aerotolerant anaerobes only ferment.

Why do facultative anaerobes grow best at the surface of the thioglycollate broth culture tubes while aerotolerant anaerobes demonstrate a uniform growth pattern throughout the tube? None of the other rationale is true The facultative anaerobes produce excessive superoxide dismutase and catalase enzymes at the thioglycollate broth's surface, which produces foam. It seems that they are growing more at the interface, which they are not. The growth pattern of the facultative anaerobes is very similar to the aerotolerant anaerobes actually. The facultative anaerobes die faster at the surface of the thioglycollate broth culture tubes as they are exposed to the oxygen but can grow towards the bottom of the tube. In contrast, the aerotolerant anaerobes are not affected by the oxygen and show and uniform growth. The facultative anaerobes grow best at the surface of the thioglycollate broth culture tubes as they can utilize the oxygen to produce a lot more ATP by aerobic respiration to promote faster growth. In contrast, aerotolerant anaerobes do not utilize oxygen even when present and grow uniformly.
