Data underlying the publication "Electric discharge by sulphide shuttling bacteria"

Sulphide oxidising bacteria (SOB) are known to spatially separate sulphide removal and current production, thereby acting as sulphide shuttles. The effect of anode potential, sulphide load and biomass concentration on discharge by sulphide shuttling SOB was investigated. SOB communities dominated by <em>Thioalkalivibrio sulfidophilus</em> were incubated with sulphide in batch experiments to produce sulphidic conditions. After sulphide had (partly) been removed the sulphidic SOB were exposed to potentials and current was measured. Discharge of sulphidic SOB were compared to discharge of aerated SOB and electrochemical oxidation of abiotic sulphide. The full methodology can be found in the related publication.
