Metrics used to quantify the resilience of E. coli to SHX-induced growth disruptiona
| Strain | Mean robustness (%) ± SDb | Mean recovery rate (h−2) ± SD | Mean recovered steady state (%) ± SDb |
|---|---|---|---|
| WT | 2.8 ± 2 | 0.1944 ± 0.0201 | 96.7 ± 3.3 |
| ΔrelA | 5.4 ± 2* | 0.0847 ± 0.0261 | ND |
| ΔgppA | 10.5 ± 0.5** | 0.1941 ± 0.0482 | 98.0 ± 12.2 |
a
Results are presented as means ± standard deviations (n = 3). *, P = 0.188; **, P = 0.01332.
b
The robustness and recovered steady state are expressed relative to the initial growth rate. ND, not determined (only one of the three biological replicates had recovered its initial growth rate 5.5 h after SHX addition).
