Anaerobic bacteria often play important roles in bioremediation. Which of the following is NOT an electron acceptor used by anaerobes during biodegradation reactions?

Question

Quizplus · Accepted Answer

Anaerobic bacteria do not use oxygen (O2) as an electron acceptor during biodegradation reactions, as they thrive in oxygen-free environments. Therefore, H2O, which is the product of reactions involving O2, is not an electron acceptor used by anaerobes. The other choices listed (CO2, SO4-2, NO3-, and Fe(III)) are commonly used electron acceptors by anaerobic bacteria.
