File S1 - Hexavalent Chromium Reduction under Fermentative Conditions with Lactate Stimulated Native Microbial Communities

Contains: Figure S1. Native microbial communities that were detected in Hanford well H-100 groundwater. (a) bacterial phyla and (b) Archaea classes. Figure S2. Non-metric multidimensional scaling of OTUs from Veillonellaceae family in bioreactors inoculated with Hanford well H-100 groundwater. Bioreactors were amended with (X) 0 mg/L Na2Cr2O7, (○) 0.1 mg/L Na2Cr2O7 and (▾) 3.0 mg/L Na2Cr2O7. W = weeks. Figure S3. Phylogenetic tree based on neighbor-joining method for predominant Archaea OTUs detected in Hanford well H-100 groundwater sample and in bioreactors inoculated with Hanford well H-100 groundwater. Bioreactors were amended with 0.0 mg/L Na2Cr2O7 (Lactate), 0.1 mg/L Na2Cr2O7 (LowCr) and 3.0 mg/L Na2Cr2O7 (HighCr). Heatmap represents temporal relative abundance. Taxonomic identification was based on NCBI-blast hits. Figure S4. Non-metric multidimensional scaling of normalized signal intensity for mcrA gene detected by Geochip in bioreactors inoculated with Hanford well H-100 groundwater.bioreactors were amended with (X) 0 mg/L Na2Cr2O7, (○) 0.1 mg/L Na2Cr2O7 and (▾) 3.0 mg/L Na2Cr2O7. W = weeks. Figure S5. Hierarchical clustering of normalized signal intensity of chrA gene probes detected in bioreactors inoculated with Hanford well H-100 groundwater. Bioreactors were amended with (X) 0 mg/L Na2Cr2O7, (○) 0.1 mg/L Na2Cr2O7 and (▾) 3.0 mg/L Na2Cr2O7. W = weeks.
