	abstract = {Two sequencing batch reactors (SBR) were constructed and filled with different inocula of activated sludge (AS) and mature fine tailings (MFT) to treat oil sands process-affected water (OSPW). The COD was reduced by 82\% in the AS-SBR and 43\% in the MFT-SBR during phase I using 10\% OSPW and 90\% synthetic wastewater as reactor feed. However, COD removal reached 12\% and 20\% in the AS-SBR and the MFT-SBR, respectively, when 100\% raw OSPW was fed into the reactors. Maximum removal of acid-extractable organics (AEO) was 8.7\% and 16.6\% in the AS-SBR and the MFT-SBR, respectively with a hydraulic retention time of one day. Pyrosequencing analysis revealed that Proteobacteria was the dominant phylum and beta- and gamma-Proteobacteria were dominant classes in both reactors. Evidence of a microbial community change was observed when influent raw OSPW was switched from 50 to 100\%. More significant changes in the AS-SBR community were detected.},
