Abstract excerpt
The survival of Escherichia coli was investigated during long-term starvation in rich media. In aerated cultures, E. coli lost the ability to form colonies earlier in NaCl-free Luria broth than in LB medium containing NaCl. Improved survival at low aeration and the sensitivity to hydrogen peroxide in aging cultures indicated a major role for oxidative stress in cell mortality. Mutants in rpoS, lacking the sigmaS...
