Over the last decade, there has been an ever-growing interest in bioelectrochemical systems (BES) as a sustainable technology enabling simultaneous wastewater treatment and biological production of, e.g. electricity, hydrogen, and further commodities. A key component of any BES degrading organic matter is the anode where electric current is biologically generated from the oxidation of organic compounds. The performance of BES depends on the interactions of the anodic microbial communities. To optimize the operational parameters and process design of BES a better comprehension of the microbial community dynamics and interactions at the anode is required. This paper reviews the abundance of different microorganisms in anodic biofilms and discusses their roles and possible side reactions with respect to their implications on the performance of BES utilizing wastewaters. The most important operational parameters affecting anodic microbial communities grown with wastewaters are highlighted and guidelines for controlling the composition of microbial communities are given.
在过去的十年中，生物电化学系统（BES）作为一种可持续技术，能够同时处理废水并生产例如电力、氢气和其他商品，引起了越来越多的关注。任何 BES 降解有机物的关键组成部分都是阳极，电流通过有机物的氧化在阳极中生物生成。BES 的性能取决于阳极微生物群落的相互作用。为了优化 BES 的操作参数和工艺设计，需要更好地理解阳极生物膜中的微生物群落动态和相互作用。本文综述了阳极生物膜中不同微生物的丰度，并讨论了它们的作用以及可能与 BES 利用废水的性能相关的副反应。突出了影响利用废水生长的阳极微生物群落的最重要的操作参数，并给出了控制微生物群落组成的指南。
