Abstract: Many biotechnologically relevant organisms cannot utilize cheap and abundant one carbon feedstocks, e.g. CO2, CO, formaldehyde, methanol, and methane, for growth and instead prefer complex feedstocks such as sugars. Disclosed herein is a system that enables organisms to consume one carbon molecules for growth and maintenance via a formyl-CoA elongation pathway.

This has the potential to be more cost effective and avoid the controversial use of food as feedstocks. Intermediates of the formyl-CoA elongation pathway may be also be converted to desired chemical products.
