  • Mediator-less biofuel cell
    Patent number: 5976719
    Abstract: The present invention provides a biofuel cell which can react with an electrode without mediator. The microorganism of a biofuel cell according to the present invention can directly consume the electrons generated from a fermentative metabolism of the microorganism through an electron metabolism without energy conservation. Therefore, if waste water is utilized as a fuel (substrate) in the biofuel cell according to the present invention, the amount of sludge production will be reduced and the efficiency of catabolizing organic materials will be increased.
