Anthropogenic activities have drastically affected the environment, leading to increased waste accumulation in atmospheric bodies, including water. Wastewater treatment is an energy-consuming process and typically requires thousands of kilowatt hours of energy. This enormous energy demand can be fulfilled by utilizing the microbial electrolysis route to breakdown organic pollutants in wastewater which produces clean water and biohydrogen as a by-product of the reaction. Microalgae are the promising microorganism for the biohydrogen production, and it has been investigated that the interaction between microalgae and bacteria can be used to boost the yield of biohydrogen. Consortium of algae and bacteria resulting around 50-60% more biohydrogen production compared to the biohydrogen production of algae and bacteria separately. This review summarises the recent development in different microalgae-bacteria granular consortium systems successfully employed for biohydrogen generation. We also discuss the limitations in biohydrogen production and factors affecting its production from wastewater.
人为活动极大地影响了环境，导致大气中包括水在内的废物积累增加。废水处理是一个耗能过程，通常需要数千千瓦小时的能源。这种巨大的能源需求可以通过利用微生物电解途径来满足，该途径可以分解废水中的有机污染物，产生清洁水和生物氢作为反应的副产品。微藻是生产生物氢的有前途的微生物，已经研究表明，微藻和细菌之间的相互作用可以用来提高生物氢的产量。与藻类和细菌单独生产生物氢相比，藻类和细菌的共生体产生的生物氢产量增加了 50-60%左右。本综述总结了最近在不同的微藻-细菌颗粒共生系统方面的发展，这些系统已成功用于生物氢的产生。我们还讨论了生物氢生产中的限制因素以及影响其从废水中生产的因素。
