微藻作为兼性好氧生物，在厌氧条件下将太阳能转化为生物氢气。生物质氢是一种理想的清洁可再生能源，具有很大的商业潜力。通过各种手段提高生物氢产率一直是人们关注的焦点。本文综述了微藻(包括蓝藻和绿藻)产氢的研究历史、固氮酶和氢酶的特性、产氢机理、技术进展以及酶、遗传和代谢工程方法在提高微藻产氢方面的应用。此外，还讨论了衣藻在发酵过程中关键酶功能中断后，对其厌氧代谢的调节。最后提出了未来微藻制氢更高效生产和商业化所面临的主要挑战和障碍。
Microalgae, as facultative aerobic organisms, convert solar energy to produce biohydrogen under anaerobic condition. Biohydrogen is a kind of ideal clean and renewable energy source with great commercial potential. Many endeavors have been focused on improving the biohydrogen yields by various means. Here, the research history of hydrogen production by microalgae (including cyanobacteria and green algae), the characteristics of nitrogenase and hydrogenase, the mechanisms of hydrogen production, the technological progress, and the application of enzymatic, genetic, and metabolic engineering methods to improve hydrogen production by microalgae are reviewed. In addition, the regulation of anaerobic metabolisms ofChlamydomonas reinhardtiiafter the disruption of key enzymes functioning in the fermentative pathways is discussed. Finally, the main challenges and obstacles facing the more efficient production and commercialization of hydrogen production from microalgae in the future are proposed.
