The present invention relates to novel hydrogenases isolated from novel hyperthermophilic strains belonging tospp., genes encoding the hydrogenases, and methods of producing hydrogen using strains having the genes. According to the hydrogen production methods of the invention, a large amount of hydrogen can be produced merely by culturing the strains in specific culture conditions. Thus, the methods of the invention have advantages in that they are more economic and efficient than existing hydrogen production methods and can produce hydrogen even at high temperature.

The present invention relates to a hyperthermophilic DNA polymerase and a preparation method thereof. The invention provides a novel hyperthermophilic DNA polymerase isolated from asp. strain, a functional equivalent thereof, a protein having the amino acid sequence thereof, and a preparation method thereof. The DNA polymerase according to the invention is a DNA polymerase, which is hyperthermophilic and has an elongation ability and fidelity higher than those of prior commercial DNA polymerases. Thus, the DNA polymerase according to the invention will be useful in precision analysis, precision diagnosis, identification and the like, which require accurate PCR.
