From: Increased susceptibility to repeated freeze-thaw cycles in Escherichia coli following long-term evolution in a benign environment

Figure 1

Survival of ancestral E. coli strain under the freeze-only (prolonged freezing) and repeated freeze-thaw cycle regimes. Each point is the log10-transformed viable cell density (CFU/mL) averaged over six replicates. Closed circles show the repeated freeze-thaw regime, and open circles show the prolonged freeze-only regime. Error bars are 95% confidence intervals and, when not visible, are smaller than the corresponding symbol.
