Identification of IbeR as a Stationary-Phase Regulator in Meningitic Escherichia coli K1 that Carries a Loss-of-Function Mutation in rpoS
Figure 5
The relative survival rate
of the BR2 mutant comparing with E44. (a) Both strains in stationary phase without
any stress treatment, (b) both strains were tested with different environmental
stress including heat shock (54 for 3 minutes), alkali (Tris pH = 10.0 for 30 minutes),
acid endurance (acetic acid, pH = 2.8 for 20 minutes), high osmolarity challenge
(2.4 M NaCl for 1 hour), and oxidative stress (10 M H2O2 for 30 minutes). Gray columns: E44; white columns: BR2. Columns marked with
are significantly different ().
