Research Progress in Anaerobic Fermentative Biohydrogen Production

This paper reviews the research progress and problems in anaerobic fermentative biohydrogen production. Enzymes in biohydrogen production, types of fermentation, researches of hydrogenase gene and biohydrogen production with unused biomass were introduced. In addition, the feasibility of biohydrogen production was also discussed in the paper, and the main problems and developing tendency were prospected. Among them, the enzymes mostly used in biohydrogen production are nitrogenase and hydrogenase; Fermentation types can be divided into butyric acid type, clostridium type and ethanol type; Many of hydrogenase gene have been sequenced, but regulation mechanism still requires a further study; Biohydrogen production technology combined with unused biomass treatment can use cheap resources such as crop straw, there is a big potential and.great development space.
