Abstract:
... The extent of chlorine inactivation and sublethal injury of stationary-phase (STAT) and long-term survival-phase (LTS) cells of Shiga toxin–producing Escherichia coli (STEC) in vitro and in a lettuce postharvest wash model was investigated. Four STEC strains were cultured in tryptic soy broth supplemented with 0.6% (w/v) yeast extract (TSBYE; 35°C) for 24 h and 21 d to obtain STAT and LTS cells, r ...

Abstract:
... The aim of this study was to investigate the inhibitory effects of benzyl isothiocyanate (BITC) and phenethyl isothiocyanate (PEITC) against Shiga toxin-producing Escherichia coli (STEC) and enterotoxigenic E. coli (ETEC). Compared with that of PEITC, the antibacterial effect of BITC was more obvious. The minimal inhibitory concentration (MIC) of BITC was 60 and 160 μmol/L for STEC and ETEC, while ...
