Increasing biological hydrogen production

氢被广泛认为是一种潜在的未来燃料，在世界范围内进行了大量的研究和开发，包括生产示范汽车和公共汽车运输系统。然而，目前还缺乏一种实用的可再生制氢手段。生物制氢有望成为一种可持续的制氢过程，因为各种废物或木质纤维底物可以转化为氢，从而有可能在产生能源的同时进行废物处理。长期以来，光合细菌因其光发酵放氢能力而被研究，并被用作光合作用、固氮和生物技术转化的模式生物。

Hydrogen is widely considered as a potential fuel of the future with a large amount of research and development world-wide, including the production of demonstration cars and bus transportation systems. However, a practical renewable means of hydrogen production is lacking. Biological hydrogen production holds promise as a sustainable process for hydrogen production since various waste products or lignocellulosic substrates could be converted to hydrogen, thus potentially producing energy and carrying out waste treatment at the same time. The photosynthetic bacteria have long been studied for their photofermentative hydrogen evolution capacity and have served as model organisms for research on photosynthesis, nitrogen fixation, and biotechnological conversions.
