This minireview summarizes the biogeochemical arsenic cycle in the alkaline, hypersaline Mono Lake. Some prokaryotes of the lake have evolved biochemical mechanisms to exploit arsenate and arsenite, using them either as an electron acceptor or as an electron donor, respectively, to support chemoautotrophic fixation of carbon dioxide into cell carbon.
