The pH of the environment influenced the expression of outer membrane protein by S. enteritidis PT4 growing in broth. Growth in broth at pH 5 to 7 resulted in variation in expression of outer membrane proteins of 18 to 22 kDa. Bacteria became acid‐fixed and non‐viable following prolonged incubation in broth with a pH below 5, and expression of flagella was repressed.
