微生物电化学系统(MES)是一种可选择的CO_(2)减排利器,能够在降解温室效应的同时将CO_(2)转化为高价值有机物,解决CO_(2)的能源与资源化问题,因此受到了极大关注。MES系统是一种电驱动的生物电化学电子转移系统,可驱动CO_(2)转化为高价值C_(1)~C_(n)有机物。电活性微生物(EAB)的胞外电子传递效率是提高MES转化效率的关键因素。因此,探索解析电活性微生物胞外电子转移规律和转化过程的影响因素,有望揭示MES的微观机理,提高MES的转化效率,突破MES商业化发展瓶颈。

Microbial electrochemical system(MES) is an optional tool for CO_(2)emission reduction.It can simultaneously degrade the greenhouse effect and convert CO_(2)into high-value organic matters, solving the problem of CO_(2)for energy and resource utilization.MES is an electrically driven bio electrochemical electron transfer system that drives the conversion of CO_(2)to high-value C_(1)-C_(n)carbon-containing organics.Through systematic regulation, CO_(2)can be transformed into methane, methanol, ethanol, acetic acid, butyric acid and other high value organic matters.Extracellular electron transfer efficiency of electroactive microorganisms is the key factor to improve the efficiency of MES transformation.In order to improve the transformation efficiency of MES,reveal the micro mechanism of MES and break through the bottleneck of commercial development, it is necessary to explore the factors affecting the extracellular electron transfer rules and transformation process of electroactive microorganisms.
