| description | O4; This study was conducted to identify bacteria responsible for the elimination of sludge in an innovative gravel contact oxidation reactor (GCOR) and a conventional activated sludge reactor (ASR),Fluorescent in situ hybridization revealed that α-,β-,γ-and ε-Proteobacteria and Bacteroidetes were present in both reactors.In the GCOR,γ-Proteobacteria accounted for 13% of the biofilm biomass on the carrier,while α-,ε-and β-Proteobacteria accounted for 12%.However,the predominant bacteria in the pores of the carrier in the GCOR were Bacteroidetes (18%),ε-Proteobacteria (13%),β-and α-Proteobacteria (10%) and γ-Proteobacteria (9%).Conversely,β-Proteobacteria (18%),Bacteroidetes (13%),α-and γ-Proteobacteria (12%) and ε-Proteobacteria (5%) dominated the sediment community of the ASR. |
