CO2 Reduction by the Iron Nitrogenase Competes with N2 Fixation Under Physiological Conditions
N. N. Oehlmann, F. V. Schmidt, M. Herzog, A. L. Goldman, J. G. Rebelein
This study shows the Fe nitrogenase in Rhodobacter capsulatus is more efficient at reducing CO2 than Mo nitrogenase but less selective for N2, leading to increased CO2 reduction to methane under physiological conditions.
