Effect of 1–8 on the integrity of B. subtilis 168 cell membranes. We measured the permeability of the cell membrane to PI by labeling B. subtilis 168 cells after treatment with compounds. We measured PI fluorescence intensity at λ620. Large values of fluorescence intensity represent an increasing membrane permeability to PI. Labels ‘E’, ‘D’, and ‘M’ stand for ethanol, DMSO, and methanol, respectively. Whisker plots display the median (center of the box), 25 to 75% of the population in the box, and 5 to 95% of the population between the outer whiskers.
