—, no data available.
Values represent site data at the time of sample collection (34; David Watson, personal communication).
BDL, below detection limit (indicates that no fluorescence signal was detected above the background).
Ranges of values represent samples from multiple homogenized soil core depth intervals for a single borehole.
Value measured in groundwater collected from an adjacent monitoring well in 2004 (http://public.ornl.gov).
Only a single depth interval contained a quantifiable number of Anaeromyxobacter 16S rRNA gene sequences.
Microcosms were established by Petrie et al. (33) from site materials collected in 2001.
