Chrysiogenes arsenatis (lat.) Is a species of obligate anaerobic chemolithoautotrophic bacteria of the monotypic genus Chrysiogenes . This is the only bacterium capable of using arsenate as the ultimate electron acceptor during the so-called "arsenate respiration."

As an electron donor, acetate , pyruvate , D- and L- lactate , fumarate , succinate and malate are used . It is a rod-shaped , curved motile (monotrich) bacterium. It was first isolated from areas of gold mines contaminated with arsenic compounds in Ballarat, Australia [1] .
Until 2010, Chrysiogenes arsenatis was the only representative of the same type and class of Chrysiogenetes , in 2010 two more genera were described.
