[Oxygen can be replaced by artificial electron acceptors in reactions catalyzed by alcohol oxidase].

For the first time, spectrometric and electrochemical studies demonstrated the possibility of using artificial electron acceptors in reactions catalyzed by alcohol oxidase. We report kinetic parameters of homogenous catalytic oxidation of formaldehyde by organic redox compounds belonging to different structural classes (toluidine blue, methylene blue, 2,6-dichlorophenolindo-phenol, and p-benzoquinone) and replacing dioxygen in these reactions. p-Benzoquinone, having the highest redox potential, proved to be the most efficient artificial electron acceptor of all compounds studied.
