Effect of rstA on EHEC O157 acid tolerance. a A heat map representing differential regulation of acid tolerance related genes in the WT and mutant strains. The z-score indicates whether the genes were upregulated (red) or downregulated (green). b Survival assay of EHEC O157 WT and the ΔrstA mutant strain in acid challenge after incubation in acidified broth (pH 3.0) for 0–6 h. Data represent mean ± SD (n = 3). *P ≤ 0.05, **P ≤ 0.01 (Student’s t-test)
