Fig 2. Effect of HICA on the cell membrane integrity of Gram-positive and Gram-negative bacteria.

Bacillus cereus NZRM5 (A), Bacillus cereus M4 (B), Staphylococcus aureus NZRM917 (C), Escherichia coli O157:H7 NCTC12900 (D), Escherichia coli AGR3789 (E), Pseudomonas aeruginosa ATCC25668 (F) and Pseudomonas aeruginosa NZRM4034 (G) were treated with 4 mg/mL HICA, and the loss of cell membrane integrity was assessed by measuring the fluorescence intensity at various treatment times. Untreated cells were used as a control. Data are presented as mean ± (s.d.) of relative fluorescence units (RFU) of three replicates (n = 3). *P < 0.05 compared with the control.
