Defense mechanism of Fe(III)-assisted anammox under salt stress: Performance and microbial community dynamics

ABSTRACT: Highlights • Fe(III)-assisted anammox exhibited superior properties treating saline wastewater.• Fe(III) promoted the synthesis of heme c and key enzymes of anammox species.• Candidatus Kuenenia could be enriched with Fe(III) addition under salt stress.• Fe(III) improve the energy metabolism of anammox species to resist high salinity. Anammox process has attracted attention due to its excellent nitrogen removal properties in nitrogen-rich wastewater treatment. However, there were some obstacles for the application of anammox to treat high saline wastewater due to its sensitivity to salinity. In this study, Fe(III) addition strategy was developed to assist anammox to adapt high saline surroundings, with the defense mechanism involved in Fe(III)-assisted anammox emphasized. Nitrogen removal
