  1. 1. For each set of perturbation data, the lowest and highest log reduction (LR) in cfu's/biofilm are listed. The perturbed conditions are compared to biofilm cultures grown on LB only medium at 37°C. cfu = colony forming unit.
  2. 2. ΔLR = the maximum observed range in log reductions (LR) between the base scenario
  3. and the perturbed culturing condition.
