  • Patent number: 9976124
    Abstract: The present invention relates to novel hydrogenases isolated from novel hyperthermophilic strains belonging to Thermococcus spp., 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.

  • Patent number: 9567576
    Abstract: The present application relates to a strain expressing the FrsA protein, and a method for producing ethanol using the same. The FrsA of the present application has a high PDC enzyme activity for a pyruvate, which is a substrate, and thus can be used in a process for producing ethanol. In addition, an FrsA mutant having improved stability in a host cell can be more effective in producing ethanol due to the increase in stability when the FrsA mutant is overexpressed together with IIAGlc, compared with when using conventional Zymomonas mobilis-derived PDC.
