File S1 - Microbial Electricity Generation Enhances Decabromodiphenyl Ether (BDE-209) Degradation

Supporting information files. Data S1 method: Response ratio (RR). Data S2 Results: Shifts of the functional genes involved in carbon, nitrogen, sulfur and phosphorus cycles. Table S1 Summary of the functional genes detected. Table S2 The gene involved in aromatic degradation. Figure S1 Voltage output (A) and polarization curve (B) of c-MFCs. Figure S2 The normalized signal intensity of the detected key gene families involved in sulfur cycling under both c-MFC and o-MFC systems. The signal intensities were the sum of detected individual gene sequences for each functional gene, averaged among three samples. All data are presented as mean±SE. **p<0.05, *p<0.10. Figure S3 The normalized signal intensity of the detected key gene families involved in phosphorus cycling under both c-MFC and o-MFC systems. The signal intensities were the sum of detected individual gene sequences for each functional gene, averaged among three samples. All data are presented as mean±SE. **p<0.05, *p<0.10. Figure S4 Principal-component analyses (PCA) of entire functional gene communities (A) and PBDE congeners (B) detected. Open circles represent samples collected from o-MFC systems and solid circles represent samples collected from c-MFC systems. Figure S5 Ordination plot produced from redundancy analysis (RDA) of entire functional gene communities on day 70 detected using GeoChip 4.0. Open circles represent samples collected from o-MFC systems and solid circles represent samples collected from c-MFC systems. Three significant PBDE congeners, BDE183, BDE-206 and BDE-208, were selected by forward selection based VIF with 999 Monte Carlo permutations.
