, and was first isolated from rabbit feces. Its type strain is strain JA1-1.
Its genome has been sequenced
and the genes required for utilising carbon monoxide as a sole carbon and energy source have been determined.
Uses
This species is the key to the technology developed by Lanzatech to create ethanol from waste carbon monoxide gas of factory emissions.
