| Abstract: | An rpoS mutant (rpoS::pRR10) of Escherichia coli O157:H7 ATCC 43895 was generated. Stationary-phase acid, heat, and salt tolerance was significantly reduced, and starvation-induced acid tolerance did not develop in the mutant. RpoS was also important for survival of E. coli O157:H7 in dry, fermented sausage. |
