Abstract

Cable bacteria have been identified and detected worldwide since their discovery in marine sediments in Aarhus Bay, Denmark. Their activity can account for the majority of oxygen consumption and sulfide depletion in sediments, and they induce sulfate accumulation, pH excursions, and the generation of electric fields. In addition, they can affect the fluxes of other elements such as calcium, iron, manganese, nitrogen, and phosphorous. Recent developments in our understanding of the impact of cable bacteria on element cycling have revealed their positive contributions to mitigating environmental problems, such as recovering self-purification capacity, enhancing petroleum hydrocarbon degradation, alleviating phosphorus eutrophication, delaying euxinia, and reducing methane emission. We highlight recent research outcomes on their distribution, state-of-the-art findings on their physiological characteristics, and ecological contributions.

电缆细菌:保护环境的广泛丝状电活性微生物。
自从在丹麦奥胡斯湾的海洋沉积物中发现缆索细菌以来,世界各地都发现并检测到了这种细菌。它们的活动可导致沉积物中大部分氧气消耗和硫化物耗竭,并引起硫酸盐积累、pH 值偏移和电场产生。此外,它们还会影响钙、铁、锰、氮和磷等其他元素的通量。最近,我们对缆索细菌对元素循环的影响的认识有了新的发展,揭示了它们在缓解环境问题方面的积极贡献,如恢复自净能力、提高石油烃降解、减轻磷富营养化、延缓休眠期和减少甲烷排放。我们重点介绍了有关其分布的最新研究成果、有关其生理特征的最新发现以及对生态的贡献。
