Changes in outer and inner membrane permeabilization caused by olanexidine and chlorhexidine in E. coli ML-35p cells incubated in 5 mM HEPES buffer containing 20 μg/ml nitrocefin and 5 μM carbonyl cyanide 3-chlorophenylhydrazone with olanexidine gluconate (A) or chlorhexidine digluconate (B). The bacteria were incubated in 5 mM HEPES buffer containing 0.75 mg/ml o-nitrophenyl β-d-galactopyranoside with olanexidine gluconate (C) or chlorhexidine digluconate (D). The concentrations of olanexidine and chlorhexidine are shown on the right side of each graph. Distilled water (DW) was used as a negative control.
