Dataset accompanying "Revealing cellular (poly)sulphide storage in electrochemically active sulphide oxidising bacteria using rotating disc electrodes"

In anaerobic conditions, sulphide oxidising bacteria (SOB) are able to spatially separate sulphide removal and electric current production. How SOB anaerobically remove sulphide, store charge and produce electric current is not yet clear. With the use of a rotating disc electrode, the redox behaviour of (poly)sulphide in absence and presence of SOB was investigated at haloalkaline conditions. Cyclic voltammetry (CV) was performed on different sulphur species in the presence or absence of SOB. Different rotation speeds and scan rates were tested.

在厌氧条件下，硫化物氧化细菌（sulphide oxidising bacteria, SOB）可实现硫化物去除与电流产生的空间分离。目前关于该类细菌在厌氧环境中完成硫化物去除、储存电荷并产生电流的具体机制尚未阐明。本研究采用旋转圆盘电极，在卤碱条件下考察了有无SOB存在时（聚）硫化物的氧化还原行为；针对存在或不存在SOB的不同硫物种开展了循环伏安法（Cyclic voltammetry, CV）测试，并对多种旋转速率与扫描速率进行了测试。
