(A) Growth rates of wild type and deficient mutants under static and shaking conditions. Strains precultured overnight at 37°C were inoculated into fresh LAPTg medium at a final OD₆₀₀ of 0.05. After 24 hr, we measured the OD₆₀₀ using a spectrophotometer. The black bar shows the static condition, and the gray bar shows the shaking condition. (LAPTg medium has no ability to consume H₂O₂.) The data are shown as the mean ± SE of three independent experiments. asterisk (*) Student’s t-test; p<0.05. (B) Growth rates of Δnpr and multiple deficient mutants under static and shaking conditions. Strains precultured overnight at 37°C were inoculated into fresh LAPTg medium at a final OD₆₀₀ of 0.05. After 24 hours, we measured the OD₆₀₀ using a spectrophotometer. The black bar shows the static condition, and the gray bar shows the shaking condition. (LAPTg medium has no ability to consume H₂O₂.) The data are shown as the mean ± SE of three independent experiments. asterisk (*) Student’s t-test; p<0.05.
