Resistance of L. casei BL23 wt (●, ○) and srtA2 (■, □) strains to H2O2 was evaluated in the stationary phase of growth of L. casei (24h—MRS). The residual population was evaluated at 0, 10, 20 and 30 min after exposure to 0.25% (●, ■) and 0.5% H2O2 (○, □). Data are presented as means ± standard deviations. Each experiment was done in triplicate, and differences between groups were compared using Student’s t-test. *: P < 0.05.
