Anaerobic corrosion of steel is accelerated by:
A) nitrifiers
B) sulfur-reducing bacteria
C) methanogenic archaea
D) all of the above
E) none of the above

Question

Quizplus · Accepted Answer

Anaerobic corrosion of steel is most commonly caused by sulfur-reducing bacteria. These bacteria use the sulfur in organic matter as an electron acceptor, leading to the production of hydrogen sulfide gas. This gas can react with the steel, causing corrosion. Nitrifiers and methanogenic archaea are not known to accelerate anaerobic corrosion of steel.
