Response to Acid Adaptation in Salmonella enterica Serovar Enteritidis

Acid adaptation in Salmonella Enteritidis was characterized by phenotypic and gene‐expression analyses. S . Enteritidis cells at log‐phase and stationary‐phase were kept at pH 4.5 to 6.0 for 1 to 4 hours. All treatments induced various levels of acid tolerance response that were dependent on pH, exposure time and growth phase. This acid adaptation resulted in tolerance to 50 °C and 8% NaCl regardless of the growth phase. However, the tolerance...
