In plant microbial fuel cells (p-MFCs) electrochemically active microbes present around the plant root convert rhizodeposits or the organic matter into electrons, protons, and CO . This work covers the increasing trend in research with p-MFCs with their mechanism of operation. Different plant species and their selection criteria are also covered. Furthermore, the long-term evaluation of such systems with its cost effectiveness and commercial and environmental perspectives are also presented. A critical aspect for bioelectricity production is the photosynthetic pathway of the plant. Additionally, the microbial communities and reactor configurations employed across different capacities are also reviewed. The challenges with bioelectricity production and the opportunity for developing p-MFCs in conjunction with traditional MFCs are also covered. These electrogenic reactor systems harness bioelectricity without harvesting the plant and has the capacity to utilize this energy for remote power applications.
在植物微生物燃料电池（p-MFC）中，植物根系周围存在的具有电化学活性的微生物将根际沉积物或有机物转化为电子、质子和二氧化碳。这项工作涵盖了p-MFC研究的增长趋势及其运行机制。还介绍了不同的植物种类及其选择标准。此外，还从成本效益、商业和环境角度对这类系统进行了长期评估。生物电生产的一个关键因素是植物的光合途径。此外，还综述了不同容量下所采用的微生物群落和反应器配置。还讨论了生物电生产面临的挑战以及结合传统MFC开发p-MFC的机遇。这些产电反应器系统无需收割植物就能利用生物电，并且有能力将这种能量用于远程供电应用。
