Recently, ensuring energy security is a key challenge to political and economic strength in the world. Bio-hydrogen production from microalgae is the promising alternative source for potential renewable and self-sustainability energy but still in the initial phase of development. Practically and sustainability of microalgae hydrogen production is still debatable. The genetic engineering and metabolic pathway engineering of hydrogenase and nitrogenase play a key role to enhance hydrogen production. Microalgae have photosynthetic efficiency and synthesize huge carbohydrate biomass, used as 4th generation feedstock to generate bio-hydrogen. Recent genetically modified strains of microalgae are the attractive source for enhancing bio-hydrogen production in the future. The potential of hydrogen production from microRNAs are gaining great interest of researcher. The main objective of this review is attentive discussed recent approaches on new molecular genetics engineering and metabolic pathway developments, modern photo-bioreactors efficiency, economic assessment, limitations and knowledge gap of bio-hydrogen production from microalgae.
最近，确保能源安全是世界政治和经济实力的关键挑战。从微藻中生产生物氢是一种很有前途的可再生能源替代来源，但仍处于发展的初始阶段。微藻制氢的实用性和可持续性仍存在争议。氢化酶和固氮酶的基因工程和代谢途径工程在提高产氢能力方面发挥着关键作用。微藻具有光合作用效率，并合成大量碳水化合物生物质，可作为第四代原料来生产生物氢。最近经过基因改造的微藻菌株是未来提高生物制氢产量的有吸引力的来源。微 RNA 产氢的潜力引起了研究人员的极大兴趣。本文综述的主要目的是讨论最近在新的分子遗传学工程和代谢途径发展、现代光生物反应器效率、经济评估、微藻生物制氢的局限性和知识空白方面的研究进展。
