Screening suitable plants that can facilitate decontamination and sustainably harvest electricity plays a crucial role in phyto-power integrated with bioelectrochemical systems (BES). Here, four plant-integrated microbial fuel cell (PMFCs) were assembled to assess decontamination and power generation performance within micro-contaminated water. The results demonstrated the L-MFC exhibited exceptional performance, achieving optimal removal rates of 53.17% for COD, 88.35% for TN, 80.51% for NO-N, 98.56% for NO-N, and 99.89% for NH-N, respectively. The same tendency is observed for power generation performance. It is attributed that plant introduction could enhance the enrichment of the exoelectrogen in the rhizosphere. Furthermore, the dominant functional bacteria such as and contributing to nitrogen cycle, autotrophic denitrification, and organic matters degradation were observed in PMFCs significantly more than that of single MFC. The present study could provide brandnew technique reference for micro-polluted water remediation in real-world scenarios.

不同植物对生态浮床-微生物燃料电池的响应：净化与发电

筛选能够促进净化和可持续获取电力的合适植物在植物发电与生物电化学系统（BES）集成中发挥着至关重要的作用。在这里，组装了四个植物集成微生物燃料电池（PMFC）来评估微污染水中的净化和发电性能。结果表明，L-MFC表现出优异的性能，COD、TN、NO-N、NO-N、NH-N的最佳去除率分别为53.17%、88.35%、80.51%、98.56%和99.89%。发电性能也观察到相同的趋势。据认为，植物的引入可以增强根际外生电的富集。此外，PMFC 中观察到的主导功能细菌（如氮循环、自养反硝化和有机物降解）明显多于单一 MFC。本研究可为现实场景中的微污染水体修复提供全新的技术参考。
