Growth, stress tolerance and motility of BSi20327 and BSi20327A. (a) Growth curves of BSi20327 in different NaCl concentrations. (b) Growth curves of BSi20327A in different NaCl concentrations. (c) Growth curves of BSi20327 and BSi20327A cultured in 3% NaCl at 15 °C. The points indicated by the three hollow boxes were the sampling times for the colony-forming unit (CFU) estimation. (d) CFU of BSi20327 and BSi20327A in the stationary phase. (e) Survival ratios of BSi20327 and BSi20327A treated with 250 nM, 500 nM and 1.5 μM H2O2. (f) Swimming motility of BSi20327 and BSi20327A on motility agar plates containing 3% NaCl. (g) Swimming motility of BSi20327 and BSi20327A on motility agar plates containing 8% NaCl. (h) Comparison of the diameters of BSi20327 and BSi20327A on motility agar plates containing 3% or 8% NaCl. The P-value is 5.08 × 10−4 at 3% NaCl and 0.011 at 8% NaCl.
