Table 2 of the original publication contained errors. The corrected values (highlighted in bold type face in the updated Table below) show that the newly reported DehaloR^2 consortium and the cells of Dehalococcoides contained therein, displayed transformation activities comparable to those of the “Unnamed” culture in Table 2, whereas transformation activities tabulated for the SDC-9 consortium were ~3-4 times higher than those of DehaloR^2. Correction of the values does not change any of the interpretations provided in the study.

The turnover rate per Dehalococcoides cell was only calculated when values for (ΔC Δt–1)max and XDhc were available from the same source and where data were from the stationary phase

aVainberg et al. (2009), (ΔC Δt–1)max was calculated from Fig. 4 and XDhc from Table 1

bXiu et al. (2010)

cCupples et al. (2004)

dHaest et al. (2010), (ΔC Δt–1)max and XDhc were calculated from Fig. 2, and XDhc was the final concentration of cells

eFreeborn et al. (2005), (ΔC Δt–1)max was from Fig. 1 and XDhc from Table 3

fRichardson et al. (2002), calculated assuming 200 μmoles TCE/bottle were reduced in 10 days

gAmos et al. (2008), (ΔC Δt-1)max was calculated from Fig. 2 and XDhc was the final concentration of cells in Fig. 1
