Starvation-induced cross protection against osmotic challenge in Escherichia coli.
Stationary-phase Escherichia coli cultures showed enhanced osmotic resistance as compared with cultures in mid-logarithmic growth or preadapted to osmotic stress. The osmotolerance that developed during starvation or osmotic adaptation required de novo protein synthesis. Of the 22 polypeptides induced during osmotic shock, five were also starvation proteins.
