Clostridium autoethanogenum

Summary

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.[1] Its genome has been sequenced [2] and the genes required for utilising carbon monoxide as a sole carbon and energy source have been determined.[3]
