Constructed wetland microbial fuel cells (CW-MFCs) or phyto-power systems are integrated bioelectrochemical systems (BES) that can sustainably harvest electricity from the anaerobic respiration of rhizospheric bacteria. This integration of techniques shows a promise in phytoremediation of wastewater along with bioenergy generation. In CW-MFCs, electrons harvested in anaerobic respiration of bacteria proliferating in the rhizospheric zone are electrochemically coupled with electron acceptors at the aerobic cathode submersed in water. Use of indigenous non-food plants in CW-MFCs has gained increasing interest primarily due to high yield of biomass that can be applied for other bioenergy purposes and bioaccumulation of pollutants. Furthermore, CW-MFCs can provide other benefits such as wastewater treatment, carbon dioxide assimilation, power generation and air purification. Microbial interaction with plant roots (rhizosphere), isolated species from the phyto-systems, with soil particles and pollutants are reviewed in this paper. In addition, successful applications of CW-MFCs are discussed with focus on power generation, the role of plant-microbe interactions as well as evaluating the critical operational parameters and their effect on power generation output efficiency.

人工湿地微生物燃料电池（CW-MFCs）或植物动力系统是集成的生物电化学系统（BES），可以持续地从根际细菌的厌氧呼吸中收集电力。这种技术的整合显示了在废水的植物修复以及生物能源产生方面的希望。在CW-MFC中，在根际区中繁殖的细菌的厌氧呼吸中收集的电子与浸入水中的好氧阴极上的电子受体电化学偶联。在CW-MFCs中使用本地非食用植物引起了越来越多的兴趣，这主要是由于可用于其他生物能源目的的高生物量产量和污染物的生物积累。此外，CW-MFCs还可以提供其他好处，例如废水处理，二氧化碳同化，发电和空气净化。本文综述了微生物与植物根部（根际），植物系统中分离出的物种，土壤颗粒和污染物之间的相互作用。此外，还讨论了CW-MFC的成功应用，重点是发电，植物-微生物相互作用的作用以及评估关键操作参数及其对发电输出效率的影响。
