Perchlorate is manufactured for the use in rocket fuels and fireworks, but it also occurs naturally on Earth and on Mars. Microorganisms, mainly proteobacteria, that use perchlorate as electron acceptor have been described. These bacteria degrade perchlorate first to chlorite, which is then dismutated to chloride and molecular oxygen. We found that Archaeoglobus fulgidus, a hyperthermophilic sulfate-reducing archaeon, is able to use perchlorate as terminal electron acceptor. The proposed pathway of perchlorate reduction in A. fulgidus relies on an interplay of abiotic and biotic redox reactions involving inorganic sulfur compounds. Based on our findings we speculate that the diversity of perchlorate-reducing microorganisms is much broader than estimated so far.
