Research Abstract |
We tried to construct high-power biofuel cells. The optimal orientation of enzymes on the electrode surface, three-dimensional immobilization of enzymes, and immobilization of plural enzymes on an electrode were investigated. We found the best treatment of the electrode for enzyme immobilization. Using a novel thermophilic alcohol dehydrogenase, a high current density was observed at 80℃more than 10 times at room temperature. An extremely high surface coverage of electrostatically active protein, 270 proteins in a fully packed monolayer, was obtained through use of the gold nanoparticle-modified electrode. We also found a novel alcohol dehydrogenase which can catalyze 4-electron oxidation of ethanol.
