PREPARATION METHOD OF ORGANIC ACID USING DEHYDROGENASE REACTION COUPLED WITH ELECTROLYTIC REDUCTION

摘要

PURPOSE: A method for preparing organic acid by a combination of electrolytic reduction and dehydrogenase reaction is provided to enhance reaction efficiency using an FAD-carbon nanotube electrode. CONSTITUTION: A method for preparing organic acid from pyruvic acid by dehydrogenage reaction comprises: a step of adding FAD and lipoamide dehydrogenase to a reaction solution for combination of electrolytic reduction and dehydrogenase reaction; a step of fixing the FAD to a carbon nanotube to prepare FAD-carbon nanotube electrode; and a step of adding the FAD-carbon nanotube electrode to the reaction solution. The organic acid is L-lactic acid.
