Abstract

At the sediment-water interfaces, filamentous cable bacteria transport electrons from sulfide oxidation along their filaments towards oxygen or nitrate as electron acceptors. These multicellular bacteria belonging to the family Desulfobulbaceae thus form a biogeobattery that mediates redox processes between multiple elements. Cable bacteria were first reported in 2012. In the past years, cable bacteria have been found to be widely distributed across the globe. Their potential in shaping the surface water environments has been extensively studied but is not fully elucidated. In this review, the biogeochemical characteristics, conduction mechanisms, and geographical distribution of cable bacteria, as well as their ecological effects, are systematically reviewed and discussed. Novel insights for understanding and applying the role of cable bacteria in aquatic ecology are summarized.

电缆细菌介导的电氧化硫及其生态效应

在沉积物与水的交界处，丝状索细菌将硫化物氧化产生的电子沿其菌丝向作为电子受体的氧气或硝酸盐输送。因此，这些属于脱硫杆菌科的多细胞细菌形成了一个生物地球电池，介导多种元素之间的氧化还原过程。电缆细菌于 2012 年首次被报道。在过去几年中，人们发现缆索细菌广泛分布于全球各地。人们对它们塑造地表水环境的潜力进行了广泛研究，但尚未完全阐明。本综述系统地回顾和讨论了缆索细菌的生物地球化学特征、传导机制、地理分布及其生态效应。总结了理解和应用缆索细菌在水生生态学中的作用的新见解。
