Patent US7709261B2. issued 2010-05-04. Retrieved from https://hdl.handle.net/1911/80019.https://hdl.handle.net/1911/80019The present invention describes a novel recombinant NADH recycling system that is used as a process for producing reduced compounds. In a specific embodiment, the reduced compounds include ethanol, succinate, lactate, a vitamin, a pharmaceutical and a biodegraded organic molecule. The NADH recycling system effects metabolic flux of reductive pathways in aerobic and anaerobic environments.42 ppengUtility patentUS7709261B2
