Chrysiogenes arsenatis is a species of bacterium in the family Chrysiogenaceae.{{cite web |author = Sayers| url=https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Undef&id=200938&lvl=6&lin=f&keep=1&srchmode=1&unlock |title=Chrysiogenetes |access-date=2016-03-20 |publisher=National Center for Biotechnology Information (NCBI) taxonomy database |display-authors=etal}} It has a unique biochemistry. Instead of respiring with oxygen, it respires using the most oxidized form of arsenic, arsenate. It uses arsenate as its terminal electron acceptor. Arsenic is usually toxic to life. Bacteria like Chrysiogenes arsenatis are found in anoxic arsenic-contaminated environments.{{cite journal |pmid=8863450 |year=1996 |last1=Macy |first1=JM |last2=Nunan |first2=K |last3=Hagen |first3=KD |last4=Dixon |first4=DR |last5=Harbour |first5=PJ |last6=Cahill |first6=M |last7=Sly |first7=LI |title=Chrysiogenes arsenatis gen. nov., sp. nov., a new arsenate-respiring bacterium isolated from gold mine wastewater |volume=46 |issue=4 |pages=1153–7 |journal=International Journal of Systematic Bacteriology |doi=10.1099/00207713-46-4-1153|doi-access=free }}
