Fig. 6From: Enhancing the antibacterial activity of antimicrobial peptide PMAP-37(F34-R) by cholesterol modificationAntibacterial activity of Chol-37(F34-R) treated at different pH. pH stability test was performed using Chol-37(F34-R) treated at different pH (2–13) by disk diffusion. a, b, c show the pH stability curves of PMAP-37, PMAP-37(F34-R), and Chol-37(F34-R) treated with different pH solutions (2–13) with S. aureus ATCC25923 as the test strain, respectively. d, e, and f show the pH stability curves of PMAP-37, PMAP-37(F34-R), and Chol-37(F34-R) treated with different pH solutions (2–13) with P. aeruginosa GIM1.551 as the test strain, respectively. The data are presented as means ± SD of results (n = 5)Back to article page
