  • Electroenzymatic reactor and method for enzymatic catalysis
    Patent number: 6306280
    Abstract: An electroenzymatic reactor comprises a reaction vessel having a working electrode compartment. Within the working electrode compartment is a reactor solution containing a redox enzyme, a redox carrier, and an oxidizable or reducible substrate. Also within the working electrode compartment is a reference electrode and a metal oxide working electrode capable of being held close to the redox potential of the redox carrier. A counter electrode is provided outside the working electrode compartment. Necessary molecular oxygen or hydrogen is supplied to the reaction by water electrolysis at the counter electrode. Hydrogen peroxide that is generated at the working electrode or counter electrode is decomposed by a screen situated near the hydrogen-peroxide generating electrode.
    Type: Grant
    Filed: May 3, 2000
    Date of Patent: October 23, 2001
