AB  - When groundwater is recharged with reclaimed water, the presence of trace amounts 
      of biorefractory pentabromodiphenyl ether (PBDE, specifically BDE-99) might cause 
      potential groundwater pollution. A laboratory-scale column was designed to 
      investigate the distribution of the community of archaea in this scenario and the 
      associated anaerobic degradation of BDE-99. The concentration of BDE-99 decreased 
      significantly as soil depth increased, and fluorescence in situ hybridization 
      (FISH) analysis suggested that archaea exerted significant effects on the 
      biodegradation of PBDE. Through 454 pyrosequencing of 16s rRNA genes, we found 
      that the distribution and structure of the archaeal community associated with 
      anaerobic degradation of BDE-99 in the river-based aquifer media changed 
      significantly between different soil depths. The primary debrominated metabolites 
      varied with changes in the vertically distributed archaeal community. The archaea 
      in the surface layer were dominated by Methanomethylovorans, and the middle layer 
      was mainly composed of Nitrososphaera. Nitrosopumilus and Nitrososphaera were 
      equally abundant in the bottom layer. In addition, Methanomethylovorans abundance 
      depended on the depth of soil, and the relative abundance of Nitrosopumilus 
      increased with increasing depth, which was associated with the 
      oxidation-reduction potential and the content of intermediate metabolites. We 
      propose that Nitrososphaera and Nitrosopumilus might be the key archaeal taxa 
      mediating the biodegradation of BDE-99.
