The effect of ED on the efflux of R6G in FLC resistant strain 24D. The R6G fluorescence of supernatant in the absence and presence of ED were determined with a Varioskan Flash (Thermo Scientific) using the SkanIt software. The extracellular concentration of R6G was calculated by using the R6G standard curve. Data are means ± SD from three experiments, ***p < 0.001, compared with the control.
