Figure 6. Relative Frequency of Biofilm Formers Increases with Resource Richness.

Figure 6

The average proportion of biofilm-forming types within five replicate populations is shown with the LB concentrations in which they evolved. Evolved populations were plated, and the number of biofilm-forming rugose- and non-forming smooth colony forming units (CFUs) were counted. Error bars indicate 95% confidence intervals. Inset: Rugose and smooth colony morphologies exhibited by V. cholerae. Images are to scale.
