We report the synthesis of veratraldehyde from veratryl alcohol by Phanerochaete chrysosporium lignin peroxidase with in situ electrogeneration of hydrogen peroxide in an electroenzymatic reactor. The effects of operating parameters such as enzyme level, pH, and electrical potential on the efficiency of veratryl alcohol oxidation were investigated. Furthermore, we compared direct addition of hydrogen peroxide with electrogeneration of the material during enzymatic oxidation of veratryl alcohol. The electroenzymatic method using in situ-generated hydrogen peroxide was found to be effective for oxidation of veratryl alcohol by lignin peroxidase. The new method may be easily applied to biodegradation systems.
