Fig. 4. Membrane potential disruption was measured as the reduced Rhodamine 123 fluorescence intensity of the tested bacteria treated with Coffea robusta leaf extract (RLE). The plotted values are the mean and the bars are the standard deviation (n = 3). ***, p < 0.001 compared to the control group. MIC, minimum inhibitory concentration. The MIC of S. aureus was 6.25 mg/ml and the MIC of B. Subtilis, E. coli, and S. Typhimurium were 12.5 mg/ml.
