Background Biological treatment of effluents containing H2S and ammonium are of great interest as both compounds can trigger serious environmental problems when disposed of. The aim of this study was to optimize the production of biosulfur from the partial oxidation of sulfide in sulfide‐ and ammonium‐containing streams. Biological performance was...

The treatment of SOx contained in flue gases generates S-rich liquid effluents that can be valorized through a two-stage biological process. The first stage consists of reducing sulfate to sulfide to be partially oxidized to sulfur in a second stage. The first biological stage is catalyzed by sulfate-reducing bacteria (SRB) and can be performed und...

Biological desulfurization has been studied during the last decades as a good option to treat sulfide rich streams as those generated for example from biogas desulfurization, anaerobic digestion of sulfate-rich wastewater or wastewater from sewer systems. These streams cause negative environmental impacts and it is necessary to implement efficient...
