Arginine and lysine decarboxylases and the acid tolerance response of Salmonella Typhimurium.

Abstract

Salmonella Typhimurium CECT 443 inactivation at pH 2.5 in Mineral Medium (MM) and MM supplemented with 0.01% (w/v) arginine, lysine or glutamic acid was studied using stationary-phase cells grown in buffered BHI pH 7.0 (non-acid adapted cells) and acidified BHI up to pH 4.5 with acetic, citric, lactic and hydrochloric acids (acid adapted cells). In all… (More)
