Producing method of hydrogen gas using novel Strain of Rhodobacter sphaeroides Having High productivity of Hydrogen and Capable of Photosynthesis in High Concentration of Salts

摘要

A novel microorganism Rhodobacter sphaeroides having excellent hydrogen producing ability is provided to improve productivity of hydrogen from organic wastewater in the presence of high concentration of salts and remove heavy metals from wastewater by accumulating them. The microorganism Rhodobacter sphaeroides KD131(KCTC 12085) produces hydrogen in the presence of 3% NaCl through photosynthesis, wherein Rhodobacter sphaeroides KD131(KCTC 12085) is isolated from the soil adjacent to the sea; and Rhodobacter sphaeroides KD131(KCTC 12085) is capable of harboring a shuttle vector pRK415, thereby easily accomplishing its gene manipulation.
