This paper reviews sulfite in the environment, sulfite chemistry, microbiology, toxicity, and its potential use for denitrification.

Our review of the literature, as well as our own lab experience, suggests that sulfite  can effectively serve as an electron donor for denitrification. Further research is needed to determine the kinetics of sulfite-based denitrification, its toxic threshold for sulfur-oxidizing microorganisms, and its potential inhibition of sensitive species such as nitrifying microorganisms and potential formation of nitrous oxide.
