Microbes exchange electrons with their extracellular environment via direct or indirect means. This exchange is bidirectional and supports essential microbial oxidation–reduction processes, such as respiration and photosynthesis. The microbial capacity to use electrons from insoluble electron donors, such as redox-active minerals, poised electrodes, or even other microbial cells is called extracellular electron uptake (EEU). Autotrophs with this capability can thrive in nutrient and soluble electron donor-deficient environments. As primary producers, autotrophic microbes capable of EEU greatly impact microbial ecology and play important roles in matter and energy flow in the biosphere. In this review, we discuss EEU-driven autotrophic metabolisms, their mechanism and physiology, and highlight their ecological, evolutionary, and biotechnological implications.

自养微生物吸收细胞外电子:生理,生态和进化意义。

微生物通过直接或间接方式与细胞外环境交换电子。这种交换是双向的,支持必需的微生物氧化还原过程,例如呼吸和光合作用。利用来自不溶性电子供体(例如氧化还原活性矿物,平衡电极或什至其他微生物细胞)的电子的微生物能力称为细胞外电子吸收(EEU)。具有这种能力的自养生物可以在营养和可溶性电子供体不足的环境中繁衍生息。作为主要生产者,能够产生EEU的自养微生物极大地影响了微生物生态,并在生物圈中的物质和能量流中发挥了重要作用。在这篇评论中,我们讨论了EEU驱动的自养代谢,其机制和生理学,并着重介绍了其生态,进化,
