这篇综述文章探讨了利用海水养殖的蓝藻作为氢气（H2）的太阳能转换器的潜力。从社会效益的角度描述了大规模可再生能源生产的海面开发以及选择经济的、基于氮酶的蓝藻制氢系统的原因。对蓝藻光生物制氢的报道进行了总结，包括比活性、太阳能转换效率和可达到的最大H2浓度。本文还讨论了在低光饱和特性、可持续性产氢等生物学参数方面需要进一步改进的问题，以及通过鉴定有前途的野生型菌株，并利用基因工程对所选菌株进行优化来克服这些困难的方法。最后，概述了在国际合作和社会接受的情况下发展经济的大规模海水养殖业务的可能机制。
This review article explores the potential of using mariculture-raised cyanobacteria as solar energy converters of hydrogen (H2). The exploitation of the sea surface for large-scale renewable energy production and the reasons for selecting the economical, nitrogenase-based systems of cyanobacteria for H2 production, are described in terms of societal benefits. Reports of cyanobacterial photobiological H2 production are summarized with respect to specific activity, efficiency of solar energy conversion, and maximum H2 concentration attainable. The need for further improvements in biological parameters such as low-light saturation properties, sustainability of H2 production, and so forth, and the means to overcome these difficulties through the identification of promising wild-type strains followed by optimization of the selected strains using genetic engineering are also discussed. Finally, a possible mechanism for the development of economical large-scale mariculture operations in conjunction with international cooperation and social acceptance is outlined.
