S. aureus growth (optical density at 600 nm) after treatment with OPP: control (open triangles ), with DMSO ( closed triangles ), 0.71 mM ( inverted closed triangles ), 0.82 mM ( closed circles ), 0.94 mM ( open squares ), and 1.18 mM OPP ( X ). Growth inhibition was performed during the exponential phase of the cells without DMSO (control) and control with DMSO, 0.71 mM, 0.82 mM, 0.94 mM, and 1.18 mM OPP dissolved in DMSO. The results are the mean of triplicate experiments; the error bars represent standard deviation.
