Antioxidant capacity analysis. a Total antioxidant capacity (T-AOC) detection. ::bfr showed stronger antioxidant capacity than the wild-type. b Survival of the wild-type, ::bfr and Δbfr strains after exposure to H2O2. Averages from three biological replicates are shown. Error bars represent the standard deviation of the mean. *, **and *** indicate P < 0.05, P < 0.01 and P < 0.005, respectively, compared to the wild-type under the same conditions
