AB  - In this study, a novel approach was developed for sulfate - containing wastewater 
      treatment via dosing Fe(2)O(3) in a two - stage anaerobic reactor (A1, S1). The 
      addition of Fe(2)O(3) in its second stage i.e. acidogenic sulfate-reducing reactor 
      (S1) resulted in microbial reduction of Fe (III), which significantly enhanced 
      the biological sulfate reduction. In reactor S1, increasing influent sulfate 
      concentration to 1400 mg/L resulted in a higher COD removal (27.3%) and sulfate 
      reduction (57.9%). In the reference reactor without using Fe(2)O(3) (S2), the COD and 
      sulfate removal were 15.6% and 29%, respectively. The combined performance of the 
      two-stage anaerobic reactor (A1, S1) also showed a higher COD removal of 74.2%. 
      Denaturing gradient gel electrophoresis (DGGE) and phylogenetic analysis showed 
      that the dominant bacteria with high similarity to IRB species as well as sulfate 
      reducer Desulfovibrio and acidogenic bacteria (AB) were enriched in S1. 
      Quantitative Polymerase Chain Reaction (qPCR) analysis presented a higher 
      proportion of sulfate reducer Desulfovibrio marrakechensis and Fe (III) reducer 
      Iron-reducing bacteria HN54 in S1.
