Stationary phase density and exponential growth rate of evolved isolates of <i>E</i>. <i>coli</i> and <i>S</i>.

<p>Typhimurium isolated after 55 cycles of growth. All values are normalized to the value for the respective ancestral strain. Three biological replicates are used in each case. Student’s <i>t</i> test was used to determine statistical significance, and correction for multiple testing was done using Bonferroni’s correction method.</p> <p>(DOCX)</p>
