Host cells transformed with hydrogenase or nitrogenase of Rhodobacter sphaeroide and method for preparing hydrogen using the same

摘要

The present invention (1) Rhodobacter spheroid (Rhodobacter sphaeroide) of the dehydrogenase of (hydrogenase) gene in transformed Escherichia (Escherichia) in a host cell and Rhodobacter spheroid nitro dehydrogenase (nitrogenase) transfected with a gene preparing a converted Escherichia in a host cell; And (2) it relates to the production of hydrogen comprises the step of producing hydrogen by culturing the host cell cavity. ; According to the invention, the dehydrogenase is remarkably improved the gene host cell transformed with the nitro dehydrogenase gene in transformed by co-culturing a host cell dehydrogenase gene in transformed host cell than when single cultures It can produce the hydrogen yield. ; Rhodobacter spheroid, hupS, hupL, dehydrogenase, nifK. nifD, nifH, nitro dehydrogenase, Escherichia in host cells
