Doubling time (days)b | Cell yield (107/μmol of Cl− released)c | |
AA0 | 1.3 ± 0.3 | 3.8 ± 0.6 |
AA1 | 0.95 ± 0.04 | 7.8 ± 0.3 |
AA4 | 0.91 ± 0.16 | 10.0 ± 0.6 |
AA20 | 0.76 ± 0.08 | 7.5 ± 2.5 |
F tests were performed to determine statistically significant differences (P < 0.05) in variances of the four conditions.
The doubling times were calculated from cell numbers during exponential growth on days 2 and 6 (tceA copies).
The Cl− released was computed using only metabolic dechlorination from TCE to VC as described by Duhamel and Edwards (6).
