  • a For VC dechlorination, moles of ethene (C2H4) produced are equal to the moles of Cl produced and the moles of VC (C2H3Cl) degraded because of the following stoichiometry: C2H3Cl + H2→C2H4 + H+ + Cl.

  • b See text for bioenergetics assumptions and calculations.

  • c Calculated from quantitative PCR data with conversion factor (see text).

  • d Measured as protein; converted to dry weight of cells by assuming 0.5 g of protein/g (dry weight) of cells.
