CO2-fixation Archives - Astrobiology

The gas conversion process by an electrode-based enzymatic reaction. The enzyme extracted from the microbe, bound to a graphite electrode, can be employed to convert the greenhouse gas carbon dioxide to formate, a molecule that can be used as safe energy storage or as a basis for chemical synthesis. The two molecules are shown as balls and sticks (carbon atoms in grey, oxygen atoms in red). The structure of the protein from the methanogen Methanothermobacter wolfeii is shown as a light blue surface to illustrate the enzyme. The energy required by the electrode can originate from renewable energy sources. CREDIT O. Lemaire, M. Belhamri and T. Wagner/ Max Planck Institute for Marine Microbiology
