Biohydrogen is a plausible alternative fuel solution for the contemporary issues regarding global warming and the steadily increasing greenhouse gas emissions, because of its high energy content and carbon-free combustion properties. Hydrogen does not exist in its natural state and the current hydrogen production technologies (steam methane reforming, water splitting) are energy-intensive, accompanied by a huge carbon footprint. Dark fermentative hydrogen production by anaerobic hydrogen-producing bacteria is a green, sustainable and emission-free pathway for hydrogen production. Microalgal biomass is considered as the third generation biofuel feedstock and is receiving academic and industrial research attention for its carbon sequestration abilities. This review discusses in detail about the pretreatment methods that could be adapted for microalgal biomass for effective biohydrogen production. Microalgal cell wall structure and the associated polymeric carbohydrates that offer certain recalcitrance are critically analyzed and future research perspectives are presented.
生物氢气是一种合理的替代燃料解决方案，可以解决当前全球变暖和温室气体排放不断增加的问题，因为它具有高能量含量和无碳燃烧特性。氢气不存在于其自然状态，并且当前的氢气生产技术（蒸汽甲烷重整、水分解）能源密集，伴随着巨大的碳足迹。厌氧产氢细菌的暗发酵制氢是一种绿色、可持续和零排放的制氢途径。微藻生物质被认为是第三代生物燃料原料，因其固碳能力而受到学术界和工业界的关注。本文详细讨论了可用于微藻生物质以有效生产生物氢气的预处理方法。对微藻细胞壁结构和相关的聚合碳水化合物进行了批判性分析，这些物质具有一定的抗降解性，并提出了未来的研究展望。
