含铁矿物常见于土壤中和地表下.在那里,它们以多种形式支撑微生物的生长和代谢,如作为微生物厌氧呼吸的电子受体、微生物自养生长的电子供体和能量来源、微生物细胞之间的电子导体和电子储存介质.微生物细胞膜套的物理化学性质决定其既不具有矿物渗透性,也不具备导电性.因此,微生物需要进化出特定的机制同胞外矿物交换电子(即胞外电子传导).微生物胞外电子传导与常见的,用于有氧呼吸的微生物细胞电子传递链有着诸多本质区别.本文中,我们概述了微生物与胞外含铁矿物之间电子传导的分子机理,以及相关的微生物在生物修复污染物、生产新型纳米材料、生物采矿和生物能源中的应用.
Iron minerals are commonly found in soils and under the surface, where they support the growth and metabolism of microorganisms in a variety of forms, such as electron acceptors that act as microorganisms for anaerobic respiration, electron donors and sources of energy for microbial autotrophic growth, Electronic conductors and electron storage media between microbial cells Microbial cell membrane sheaths have a physico-chemical nature that determines neither mineral permeability nor electrical conductivity Therefore, microorganisms need to evolve into specific mechanisms that interact with extracellular mineral exchange electrons Extracellular Electron Conduction.) There are a number of essential differences between extracellular electron conduction of microorganisms and the common electron transport chain of microbial cells used for aerobic respiration. In this article, we outline the electronic conduction between microorganisms and extracellular iron minerals Molecular mechanisms and the application of related microorganisms in the bioremediation of contaminants, the production of novel nanomaterials, bio-mining and bioenergy.
