    摘要:

    微生物胞内产生的电子转移到其他电子受体而获得能量的过程称为微生物胞外电子传递，其中，另一微生物作为电子受体时发生的电子传递称为微生物种间电子传递。根据微生物种间电子传递机制，可分间接种间电子传递和种间直接电子传递。由于种间直接电子传递不需要其他物质介导，因此较间接种间电子传递效率更高、能量利用更高。本文系统阐述了微生物进行胞外电子传递的机理及应用，重点分析了种间直接电子传递机理，并概述种间直接电子传递应用领域，为寻找更多电连接的微生物群落以及应用微生物提供参考。

    Abstract:

    Extracellular electron transfer (EET) refers to the process of transferring electrons generated in microorganisms to other electron acceptors to obtain energy, and the electron transfer that occurs between two different microorganisms is called microbial interspecies electron transfer (IET). IET can occur in two ways: mediated interspecies electron transfer (MIET) and direct interspecies electron transfer (DIET). Without of the need for other material mediation, DIET has higher efficiency and energy utilization efficiency than MIET. This paper systematically expounds the mechanisms and applications of EET in microorganisms, with focus on the mechanisms and potential application fields of DIET. This review aims to provide a reference for finding more electrically connected microbial communities and applied microorganisms.
