BR50 values for AHLs, rhamnolipids, and HAA.a
| Amphiphile | BR50 Value (μM)a | 95% CI (μM) |
|---|---|---|
| 3-oxo-C12-AHL | 7.1 | 6.7–7.6 |
| 3-oxo-C12-HS | 20 | 14–29 |
| 3-OH-C12-AHL | 16 | 13–20 |
| C10-AHL | >72 | – |
| C8-AHL | >360 | – |
| C6-AHL | – | – |
| C4-AHL | – | – |
| HAA | 2.3 μg/mL (8 μM) | 2.1–2.5 μg/mL |
| Rhamnolipids | 5.9 μg/mL (~7–20 μM)b | 5.1–6.9 μg/mL |
a
BR50 is defined as the minimum concentration required to induce changes from bipolar to radial states in at least a 50% of LC droplets. Values were obtained from sigmoidal regressions to the data plotted in Figures 3 and S2. CI = confidence interval.
b
We estimate the molar concentration of a 6 μg/mL mixture of commercial rhamnolipids to be in this micromolar range; see SI for additional details.
