Similar to Escherichia coli O157, non‐O157 also inherits certain acid resistance, and its stress response can be induced under acidic conditions, which may be affected by temperature. In this study, O26, the main serotype of non‐O157 E. coli, was investigated in order to evaluate the effect of lactic acid stress on its biofilm formation (BF) at different temperatures. Firstly, the BF ability of 22...
This study was aimed to investigate the effects of lactic acid stress with acid adaptation on the survival and expression of virulence‐related genes in Escherichia coli O157:H7 (strains CICC21530, 89, 95, 112, 109, and J42). E. coli were subjected to acid adaption (pH 5.0) for 1–4 hr and then exposed to acid stress (pH 3.5) for 30–120 min. Results showed that exposure to pH 3.5 decreased the survival...
