Abstract:
The present invention relates to novel hydrogenases separated from new hyperthermophilic strains belonging to Thermococcus genus, genes encoding the same, and a method for producing hydrogen using the same. According to a method for producing hydrogen of the present invention, a large amount of hydrogen can be produced only by culturing the strains in a specific culture condition and therefore, it is more economical and effective compared to the existing method for producing hydrogen and hydrogen can be produced at a high temperature.
