Clostridium autoethanogenum is an anaerobic bacterium that produces ethanol from carbon monoxide, in so-called syngas fermentation, being one of the few known microorganisms to do so. It is gram-positive, spore-forming, rod-like, motile, and was first isolated from rabbit feces. Its type strain is strain JA1-1.{{cite journal|last1=Abrini|first1=Jamal|last2=Naveau|first2=Henry|last3=Nyns|first3=Edmond-Jacques|title=Clostridium autoethanogenum, sp. nov., an anaerobic bacterium that produces ethanol from carbon monoxide|journal=Archives of Microbiology|volume=161|issue=4|year=1994|pages=345–351|issn=0302-8933|doi=10.1007/BF00303591|s2cid=206774310}} Its genome has been sequenced {{cite journal|last1=Bruno-Barcena|first1=J.
