Escherichia coli O157:H7 NCTC12900 (A), Escherichia coli AGR3789 (B), Pseudomonas aeruginosa ATCC25668 (C) and Pseudomonas aeruginosa NZRM4034 (D) were treated with various concentrations (0.5–4 mg/mL) of HICA, and the outer membrane permeability was assessed by measuring the fluorescence intensity.
