Microbial electrochemical systems (MESs) are a highly versatile platform technology with a particular focus on power or energy production. Often, they are used in combination with substrate conversion (e.g., wastewater treatment) and production of value-added compounds via electrode-assisted fermentation. This rapidly evolving field has seen great improvements both technically and biologically, but this interdisciplinarity sometimes hampers overseeing strategies to increase process efficiency. In this review, we first briefly summarize the terminology of the technology and outline the biological background that is essential for understanding and thus improving MES technology. Thereafter, recent research on improvements at the biofilm-electrode interface will be summarized and discussed, distinguishing between biotic and abiotic approaches. The two approaches are then compared, and resulting future directions are discussed. This mini-review therefore provides basic knowledge of MES technology and the underlying microbiology in general and reviews recent improvements at the bacteria-electrode interface.
微生物电化学系统（MESs）是一种高度通用的平台技术，特别侧重于发电或产电。通常，它们与基质转化（例如，废水处理）结合使用，并通过电极辅助发酵生产增值化合物。这个快速发展的领域在技术和生物学方面都取得了巨大的进步，但这种跨学科性有时会阻碍提高工艺效率的监督策略。在这篇综述中，我们首先简要总结了该技术的术语，并概述了理解和因此改进 MES 技术所必需的生物学背景。此后，将总结和讨论生物膜-电极界面的最新改进，区分生物和非生物方法。然后对这两种方法进行比较，并讨论未来的发展方向。因此，本迷你综述提供了 MES 技术和一般微生物学的基础知识，并综述了细菌-电极界面的最新改进。
