An integrated photo-bioelectrochemical (IPB) system uses microalgae in the cathode of a microbial fuel cell to achieve higher electricity generation and nutrient removal from wastewater. Using multivariate analysis and surveys of IPB studies, this paper identifies key algal and bacterial taxa and discusses their functions critical for IPB performance. Unicellular algae with high photosynthetic oxygen production and biofilm formation can enhance IPB energy production. Diverse bacterial taxa achieve nitrogen transformations and can improve total nitrogen removal. Understanding bacteria-algae interactions via quorum sensing in the IPB cathode may potentially aid in boosting system performance. Future advances in development of IPBs for wastewater treatment will benefit from interdisciplinary collaboration in analysis of microbial community functions.

提高集成光生物电化学系统的性能：细菌 - 藻类群落中的分类群和功能。

集成光生物电化学 (IPB) 系统在微生物燃料电池的阴极使用微藻，以实现更高的发电量和废水中的养分去除。通过对 IPB 研究的多变量分析和调查，本文确定了关键的藻类和细菌类群，并讨论了它们对 IPB 性能至关重要的功能。具有高光合产氧量和生物膜形成的单细胞藻类可以增强 IPB 能量产生。不同的细菌类群实现氮转化，并可以提高总氮去除率。通过 IPB 阴极中的群体感应了解细菌-藻类相互作用可能有助于提高系统性能。用于废水处理的 IPB 开发的未来进展将受益于微生物群落功能分析的跨学科合作。
