【Abstract】 Hydrogen gas is considered as the ideal energy for the sustainable development of our society.In this review,the state-of-art of photo-biological hydrogen production by microalgae was evaluated.The biological principles were presented,focusing on the enzymatic mechanisms and process engineering.Three methods of photo-biological hydrogen production were compared;hydrogen production by nitrogenase,direct biophotolysis and indirect biophotolysis by reversible hydrogenase.It is concluded that two-stage indirect biophotolysis by reversible hydrogenase holds the greatest potential for the future development.The problems and prospects for realizing this potential were discussed,which required a major breakthrough in genetic engineering and metabolic regulation of hydrogen metabolism in microalgae.;更多还原
