Anaerobic fermentation bio-hydrogen production has captured extensive attention, hydrogen-production microorganisms has become the research focus as core role. Based on the review of current status and main achievements of hydrogen-producing microorganisms research both domestic and abroad, the fermentative type, the hydrogen-production capability, the bacterium type, breeding, and the gene modification were presented. The main associated issues were analyzed and the research prospects were put forward.
