Figure 5. Biofilm Formation in Different Resource Concentrations.

Figure 5

Biofilm formation increased among all evolved strains (filled black points). However, strains that evolved in resource-rich environments (LB concentrations of approx. 0.75x and above) formed substantially larger biofilms than those that evolved in resource-poor environments (LB concentrations below 0.75x). The wild type ancestral strain formed weak biofilms in all environments (open grey points). Error bars indicate 95% confidence intervals.
