The cytoplasmic membrane permeabilization of S. aureus cells treated with sonorensin (squares) and nisin (circles).
The untreated S. aureus cells (triangles) were taken as control. When the cytoplasmic membrane was permeable ONPG entered the cytoplasm and degraded by β-galactosidase, producing O-nitrophenol that showed absorbance at 405 nm. Sonorensin induced an increase in the permeability of S. aureus. The experiment was carried out three times in triplicate. The results were presented as mean ± SD and differences between the control and treated samples were statistically significant (n = 3) (p < 0.005).
