微藻制氢的研究进展

化石能源的不可再生性和使用过程中造成的环境污染使开发新能源变得非常迫切。氢是理想的能源,因此,利用微藻制氢具有诱人前景。本文综述了微藻光合制氢技术的研究历史、固氮酶和可逆产氢酶的产氢机制及研究进展;介绍了基于微藻的硫缺乏生理调控而发展起来的一步法与两步法光解制氢的方式;指出了利用微藻可逆产氢酶两步法间接光水解制氢最具开发潜力;分析了实现微藻光合制氢的限制因子和存在的问题;归纳了今后的主要研究方向。

PROGRESS IN STUDIES ON PRODUCING HYDROGEN USING MICROALGAE

Environmental pollution arose and unrenewable from utilization of fossil energy source which is encourage people to explore new energy source.Producing hydrogen using microalgae have temptation future since hydrogen is a kind of ideal renewable energy source.History,biological mechanism as well as progress of producing hydrogen by nitrogenase reversible hydrogenase are summarized.The one-step and two-step indirect biophotolysis by reversible hydrogen based on sulfur-deprived culture are also introduced.It is concluded that two-step indirect biophotolysis by reversible hydrogenase hold the greatest potential for future development.Some limiting factors and problems for producing hydrogen using microalgae in large scale are analyzed and prospective direction is pointed out finally.
