The effect of acidified nitrite on
SalmonellaTyphimurium and
Escherichia coli O157:H7 (EHEC) under food-related conditions was investigated. The lysine decarboxylase CadA was found to contribute to nitrite resistance of
S. Typhimurium. Furthermore, a decrease of the intracellular pH due to acidified nitrite was observed. Transcriptome studies revealed that, besides a NO-specific response including up-regulation of NO-detoxifying enzymes HmpA and/or NorV, other stress-associated systems were induced.
