  Reference text
  Chaudhuri et al. (2002). Environmental factors that control microbial perchlorate reduction.
  Curator note
  The methods supply sodium perchlorate as acceptor. Results demonstrate oxygen and nitrate effects; this role is restricted to the described perchlorate-respiring organisms and anoxic conditions.
Metabolic context
Terminal electron acceptor for Dechlorosoma suillum PS and Dechloromonas agitata CKB during anoxic, acetate-fed culture.
