背景：生物电化学系统(BESS)是一种新兴的节能环保技术。BESS的不同应用能够有效地减少废物和处理废水，同时通过特定的氧化还原反应回收电力、生物氢和其他增值化学品。虽然在过去的十年里，有许多研究极大地提高了BESS的性能，但关于BESS在农业方面的应用的研究和综述非常有限。考虑到人口增长对粮食、能源和水的需求不断增加，迫切需要新技术来提高农业的生产率和可持续性。方法：本综述研究基于对主要在过去几十年(即2009-2018年)与农业相关的BES研究的广泛文献搜索。这项综述研究中使用的数据库包括Scope us、Google Scholar和Web of Science。讨论了生物电化学技术在农业中的应用现状和前景。结果/结论：BESS具有从农业废物和废水中回收相当数量的电力和能源化学品的潜力。回收的能源可用于减少对农业系统的能源投入。贝斯还可以生产生物燃料、植物营养素和灌溉用水等其他资源和增值化学品。此外，Bess可能会取代不可持续的电池为远程传感器供电，或者被设计为农业监测的生物传感器。还讨论了使用BESS生产不需要阳光的食品和修复受污染土壤的可能应用。同时，农业废弃物还可以加工成建筑材料或生物炭电极/电催化剂，以降低目前BESS的高昂成本。未来的研究应该评估农场BES应用的长期性能和稳定性。
Background: Bioelectrochemical systems (BESs) are emerging energy-effective and environment-friendly technologies. Different applications of BESs are able to effectively minimize wastes and treat wastewater while simultaneously recovering electricity, biohydrogen and other value-added chemicals via specific redox reactions. Although there are many studies that have greatly advanced the performance of BESs over the last decade, research and reviews on agriculture-relevant applications of BESs are very limited. Considering the increasing demand for food, energy and water due to human population expansion, novel technologies are urgently needed to promote productivity and sustainability in agriculture. Methodology: This review study is based on an extensive literature search regarding agriculture-related BES studies mainly in the last decades (i.e., 2009–2018). The databases used in this review study include Scopus, Google Scholar and Web of Science. The current and future applications of bioelectrochemical technologies in agriculture have been discussed. Findings/Conclusions: BESs have the potential to recover considerable amounts of electric power and energy chemicals from agricultural wastes and wastewater. The recovered energy can be used to reduce the energy input into agricultural systems. Other resources and value-added chemicals such as biofuels, plant nutrients and irrigation water can also be produced in BESs. In addition, BESs may replace unsustainable batteries to power remote sensors or be designed as biosensors for agricultural monitoring. The possible applications to produce food without sunlight and remediate contaminated soils using BESs have also been discussed. At the same time, agricultural wastes can also be processed into construction materials or biochar electrodes/electrocatalysts for reducing the high costs of current BESs. Future studies should evaluate the long-term performance and stability of on-farm BES applications.
