摘要
在地表环境中,铁氧化物矿物可以作为微生物胞外呼吸的终端电子受体/供体、电子储存介质或种间电子传递介质促进环境微生物的新陈代谢。本文介绍了矿物-微生物直接界面电子转移方式中,铁氧化物矿物与组成微生物跨膜电子传输链的细胞色素蛋白之间的氧化-还原反应机制及其影响因素,从分子水平刻画了微生物利用矿物进行胞外呼吸的过程,有助于深入理解微生物驱动的矿物转化和元素地球化学循环。
In the surface environment,iron oxide minerals can promote microbial metabolism as a terminal electron donor/acceptor,environmental battery,or a conductor for direct interspecies electron transfer,and so on.This paper introduced the up-to-date studies about molecular mechanisms and influencing factors on the interaction between iron oxide minerals and c-type cytochromes of extracellular electron transfer pathways,including the binding of cytochromes onto the surface of iron oxide minerals,effects of mineral properties on interfacial electron transfer,and main environment variables controlling extracellular electron transfer,etc.
