  • Title: Selection for loss of RpoS in Cronobacter sakazakii by growth in the presence of acetate as a carbon source.
    Author: Álvarez-Ordóñez A, Begley M, Hill C.
    Journal: Appl Environ Microbiol; 2013 Mar; 79(6):2099-102. PubMed ID: 23335773.
    Abstract:
    We demonstrate that growth of Cronobacter sakazakii in the presence of acetate as a carbon source promotes loss of RpoS, with a consequent reduction in stress tolerance. This suggests that C. sakazakii is capable of regulating cell fitness through mutation of the rpoS gene.
