The tests were performed using 10 µL/mL and 20 µL/mL. All tests were performed in triplicate. Results are expressed as percentages (mean ± SD) and calculated assuming the control (untreated bacteria, for which we assumed an inhibitory value = zero). a: p < 0.1; compared with the control (ANOVA followed by Dunnett’s multiple comparison test).
