The Anaerobic Organisms Used in Sewage Treatment May Produce the Useful

Question

The anaerobic organisms used in sewage treatment may produce the useful product(s)
A)oxygen.
B)nitrogen.
C)carbon monoxide.
D)methane.
E)nitrogen AND carbon monoxide.

Accepted Answer

Anaerobic organisms used in sewage treatment, such as methanogenic bacteria, produce methane gas as a byproduct of their metabolism. This methane can be collected and used as a source of energy, making it a useful product of the sewage treatment process. Option A is incorrect as anaerobic organisms cannot produce oxygen, which is a byproduct of photosynthesis. Option B is incorrect because anaerobic organisms do not produce nitrogen gas. Option C is incorrect as carbon monoxide is a toxic gas that is not a useful product of sewage treatment. Option E is incorrect as anaerobic organisms do not produce carbon monoxide.
