FIG 6.
H2O2 accumulation (A), NADH peroxidase activity (B), and cell survival during 144 h of storage at 4°C (C) of the wild-type L. brevis ATCC 367, Δpdh mutant, and Δpox mutant strains after 24 h of anaerobic or aerobic cultivation. The values are means ± standard deviations of three independent experiments. Statistically significant differences are indicated by asterisks (*, P < 0.05).
