FIGURE 2.

The inhibitory effect of Lp299 and Lp299v on S. aureus is pH‐dependent. S. aureus was incubated with Lp299, Lp299v, or cell‐free supernatants from overnight cultures of the lactobacilli. To explore the role of pH, S. aureus was also incubated with pH‐neutralized supernatants and with acidified MRS broth. The bars with an asterisk above them indicate a significant growth inhibition compared to the control with S. aureus grown in a mixed broth without lactobacilli. SN =supernatant. Neu =neutralized. *p < 0.05
