Abstract/OtherAbstract:
The bactericidal effect of acidified sodium nitrite alone or when combined with high hydrostatic pressure treatment (HHP) was examined with Escherichia coli BW25113 and Listeria monocytogenes NCTC 11994. A powerful synergistic effect of HHP plus nitrite was observed at pH 4.0 but not at higher pH values. E. coli hmpA and norV mutants lacking defences against nitrosative stress were more sensitive to pressure combined with acidified sodium nitrite than the wild type strain suggesting an involvement of nitric oxide in the bactericidal effect. © 2012 The Authors Letters in Applied Microbiology © 2012 The Society for Applied Microbiology.
