TABLE 2.
MICs for E. coli strains upon exposure to a range of MeHg concentrationsa
| Construct | MIC (μM) |
ANOVAb | ||
|---|---|---|---|---|
| Avg | Range | SD | ||
| pET9a (empty vector) | 7.33 | 7–7.5 | 0.29 | a |
| pHYR1a (merA) | 7.17 | 6.5–7.5 | 0.58 | a |
| RN23B (merB) | 4.5 | 4–5 | 0.5 | b |
| pHYR1a + RN23B (merA + merB) | 14.33 | 13–15 | 1.15 | c |
a
pET9a was used as an empty vector control and is indicative of bacteria lacking any mercury resistance mechanisms.
b
Significance of differences in MICs of MeHg, as determined by a one-way ANOVA with Tukey’s HSD for each pairwise comparison. P < 0.05. n = 3.
