  • Method of producing hydrogen gas by using hydrogen bacteria
    Patent number: 6860996
    Abstract: Both organic waste or wastewater and methane-generating bacteria are contained in organic waste or wastewater. When organic waste or wastewater containing these bacteria is cultured as a base material, the hydrogen produced by the hydrogen-generating bacteria is consumed by the methane-generating bacteria. The purpose of the invention is achieved by controlling the biophase with heat treatment so that the activity of hydrogen-generating bacteria having sporulation ability contained in the organic waste is maintained, while the hydrogen-consuming, methane-producing bacteria are decreased. Specifically, this invention provides a method of effectively generating hydrogen gas using hydrogen-generating bacteria by adjusting the treatment temperature to 68-95° C., and adjusting the treatment time and pH.
