Sulfide- and nitrate-laden wastewaters at 2¡V35?g/L NaCl were treated by DSR process. A C/N ratio of 3:1 was proposed to maintain high S0 conversion rate. The granular sludge with a compact structure and smooth outer surface was formed. The microbial communities of DSR consortium via high-throughput sequencing method suggested that salinity shifts the predominating heterotrophic denitrifiers at <10?g/L NaCl to autotrophic denitrifiers at >10?g/L NaCl. ? 2015, Springer-Verlag Berlin Heidelberg.Denitrifying sulfide removalEGSBGranular sludgeHigh salinityjournal article10.1007/s00253-015-6505-52-s2.0-84937637888https://www.scopus.com/inward/record.uri?eid=2-s2.0-84937637888&doi=10.1007%2fs00253-015-6505-5&partnerID=40&md5=7fedf38bc785515aca908d9c3d0f7d26
