Figure 4From: Capsule deletion via a λ-Red knockout system perturbs biofilm formation and fimbriae expression in Klebsiella pneumoniae MGH 78578The fold change in the amount of uronic acid (capsule) and biofilm produced by the Δcps and Δwzabc mutants relative to the wild-type (WT). Error bars represent the standard deviation of three biological replicates. The uronic acid data is identical to that found in Figure 2 but presented here as fold change.Back to article page
