rpoS regulation of acid, heat, and salt tolerance in Escherichia coli O157:H7

1996

Cheville, A.M. | Arnold, K.W. | Buchrieser, C. | Cheng, C.M. | Kasper, C.W.

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 day, fermented sausage.
