Anaerobic treatment of sulfate-rich wastewaters is challenging due to the inevitable biological sulfate reduction to sulfide, which limits biogas use and can negatively impact the treatment performance due to the toxic character of sulfide. Establishing sulfidogenesis during fermentation has recentl...
