Abstract
A process for converting a substrate such as carbon monoxide to useful chemicals has been developed. The process involves providing a substrate comprising CO to a bioreactor which contains a culture of one or more micro-organisms and anaerobically fermenting the substrate to produce ethanol. The ethanol is next converted to one or more chemical products via the compound ethylene. The source of the CO can be an industrial process such as the ferrous metal products manufacturing. The microorganism can be Clostridium autoethanogenum, Clostridium ljundahlii or Clostridium ragsdalei.

1 to 19. (canceled)
A method for producing one or more chemical products, the method comprising;
- a. flowing a gaseous substrate comprising CO into a bioreactor containing a culture of one or more microorganisms;
- and
- b. anaerobically fermenting the substrate comprising CO to produce ethanol;
- and
- c. converting the ethanol produced in step (b) to one or more products via the intermediate compound ethylene.
