Expression of outer membrane proteins by Salmonella enteritidis relating to pH.
The pH of the environment influenced the expression of outer membrane proteins 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.
