Conventional wastewater treatment using activated sludge cannot efficiently eliminate nitrogen and phosphorus, thus engendering the risk of water eutrophication and ecosystem disruption. Fortunately, a new wastewater treatment process applying microalgae-bacteria consortia has attracted considerable interests due to its excellent performance of nutrients removal. Moreover, some bacteria facilitate the harvest of microalgal biomass through bio-flocculation. Additionally, while stimulating the functional bacteria, the improved biomass and enriched components also brighten bioenergy production from the perspective of practical applications. Thus, this review first summarizes the current development of nutrients removal and mutualistic interaction using microalgae-bacteria consortia. Then, advancements in bio-flocculation are completely described and the corresponding mechanisms are thoroughly revealed. Eventually, the recent advances of bioenergy production (i.e., biodiesel, biohydrogen, bioethanol, and bioelectricity) using microalgae-bacteria consortia are comprehensively discussed. Together, this review will provide the ongoing challenges and future developmental directions for better converting nitrogen and phosphorus wastewater into bioenergy using microalgae-bacteria consortia.
使用活性污泥的传统废水处理方法无法有效去除氮和磷，从而产生水体富营养化和生态系统破坏的风险。幸运的是，一种应用微藻-细菌联合体的新型废水处理工艺因其出色的营养物质去除性能而引起了广泛关注。此外，一些细菌通过生物絮凝促进微藻生物质的收获。此外，在刺激功能细菌的同时，从实际应用的角度来看，提高的生物质和丰富的成分也为生物能源生产带来了光明前景。因此，本综述首先总结了使用微藻-细菌联合体进行营养物质去除和共生相互作用的当前发展情况。然后，全面描述了生物絮凝的进展，并深入揭示了相应的机制。最后，全面讨论了使用微藻-细菌联合体进行生物能源生产（即生物柴油、生物氢气（生物氢）、生物乙醇和生物电）的最新进展。总之，本综述将为利用微藻-细菌联合体更好地将氮磷废水转化为生物能源提供当前面临的挑战和未来的发展方向。
