day and night while the mutant photosynthetic bacteria to produce hydrogen production method and hydrogen production method using mutant and that it

摘要

the present invention is an anaerobic hydrogen-generating enzyme was expressed that the involvement of foreign Rhodobacter sphaeroides ( Rhodobacter sphaeroides ) relates to the production of hydrogen-derived mutant. Existing Rhodobacter sphaeroides wild type strain is possible to produce hydrogen of high efficiency due to the action of nitrogenase enzyme in photosynthetic condition, but the absence of light at night, while the limits that can not produce hydrogen gatneunde, improved mutant provided by the present invention the case can be made of hydrogen production by anaerobic hydrogen-producing enzymes at night without a light is introduced from a foreign expression, and the Rhodobacter Spanish Roy in case of death derived mutant photosynthetic light given the existing conditions with nitrogen-fixing enzyme has an improved hydrogen producing ability than is possible with the introduction of anaerobic hydrogen-producing enzymes which act at the same time.
