摘要
微藻光合作用制氢是解决能源短缺问题的有效途径。本文介绍了微藻光合作用制氢的机理,包括蓝藻固氮酶和可逆氢酶产氢以及绿藻可逆氢酶产氢的机理。在分析光合制氢限制因素的基础上,指出筛选和构建高效放氢藻株是制氢的有效途径。然后介绍了“直接生物光解”、固氮酶放氢和“间接生物光解”等制氢方式。利用绿藻“间接生物光解”水制氢是一种最有发展潜力的制氢方式。本文最后展望了微藻光合制氢的前景。
Micioalgal photosynthetic hydrogen production is an effective way to solve our energy crisis.This review summarized the mechanism of microalgal photosynthetic hydrogen production,including hydrogen production catalysed by nitrogenase and reversible hydrogenase in cyanobacteria,and also by reversible hydrogenase in green algae.Based on analysis of the limiting fators of photosynthetic hydrogen production,both the classical mutagenesis/screen approach and the molecular biology approach were recommended to improve the hydrogen production rate.Hydrogen production by nitrogenase,direct biophotolysis and indirect biophotolysis were compared to show indirect biophotolysis by green algae have the greatest potential for future applied R&D.The prospects of microalgal photosynthetic hydrogen production were discussed.
