Factors influencing alkali-induced heat resistance in Salmonella enteritidis phage type 4

The culture of cells of Salmonella enteritidis PT4 at either 25, 30 or 37°C in media at pH values between 8.0 and 9.75 resulted in significant increases in heat resistance. At 37°C, induction was rapid and was dependent on protein synthesis, being inhibited by chloramphenicol. Thermotolerance was st...

Description
Summary:The culture of cells of Salmonella enteritidis PT4 at either 25, 30 or 37°C in media at pH values between 8.0 and 9.75 resulted in significant increases in heat resistance. At 37°C, induction was rapid and was dependent on protein synthesis, being inhibited by chloramphenicol. Thermotolerance was stable when cells were transferred from pH 9.2 to pH 7.0 and cultures only became heat sensitive again following significant multiplication at the lower pH.
