Starvation- and stationary-phase-induced acid tolerance in Escherichia coli O157:H7.
Stationary phase and the starvation of log-phase cells increased the acid tolerance of Escherichia coli O157:H7 strains. Although the degree of acid tolerance varied, the survival of most O157:H7 strains exceeded that of other, related, pathogens in a synthetic gastric fluid.
