FIG. 5.

Effects of nitrosative stress on the viability of different B. subtilis strains. Aerobically growing cultures were challenged with 10 mM SNP for 30 min and then plated on TBAB medium. CFU are plotted as a percentage of the values for untreated cultures. The results are the means from at least three independent experiments. Error bars indicate the standard deviation. Strains 1A1 (wild type [wt]), LUW219 (ΔyjbIH), LUW219/pCW7, LUW219/pCW7-yjbI, LUW219/pCW7-yjbH, LUW219/pCW7-yjbIH, LUW272 (ΔyjbH), LUW272/pCW7, LUW272/pCW7-yjbH, LUW222 (yjbI insertion) without IPTG, and LUW222 with IPTG were used.
