Effect of trisodium phosphate adaptation on changes in membrane lipid composition, verotoxin secretion, and acid resistance of Escherichia coli O157:H7 in simulated gastric fluid.

Abstract excerpt

Escherichia coli O157:H7 (HEC), E. coli O157:H7 rpoS mutant (HEC-RM), and nonpathogenic E. coli (NPEC) were step-wise adapted to trisodium phosphate (TSP) by incubation in broths of increasing concentration, from 0% to 0.6%, at 37 degrees C for 24 h. After incubation at each concentration, each population was examined for acid resistance (D value) in simulated gastric fluid of pH 1.5, cell envelope membrane lipid...
