[Bioelectrochemical oxidation of formate].
The process of electrochemical oxidation of formate on a coal electrode with the help of a two-enzyme system composed of NAD-dependent formate dehydrogenase and NADH-dehydrogenase, catalysing oxidation of NADH with reduction of methylviologen was studied. In this system the oxidation of formate proceeds in the diffusion regime. Under experimental conditions the value of current density at a potential higher than +0,2 V and at the rotating rate of 600 rpm is 12 mA/cm2. The results obtained show that NAD-depend dehydrogenases can be used for electrochemical oxidation of organic compounds which are their substrates.
