Summary
Enzymatically active NADH was formed from NAD+ directly in the electrochemical system by adopting an anion-charged membrane as a diaphragm and applying the less cathodic potential of −0.7V vs. Ag/AgCl electrode. The direct electrochemical procedure worked favorably as an NADH regenerator in the biochemical reaction system using D-lactate dehydrogenase which transforms pyruvate to D-lactate.
