Figure 4. Effect of non-ionic surfactant supplementation on phage cocktail adsorption to K. pneumoniae CAV1016 biofilms. Navy bars represent phage cocktail 1 (PC1, ∼109 PFU/mL) and phage cocktail 2 (PC2, ∼107 PFU/mL) without P103. Light blue bars represent phage cocktail 1 (PC1, ∼109 PFU/mL) and phage cocktail 2 (PC2, ∼107 PFU/mL) with P103. Values are log-normalized means ± SEM (n = 9). Asterisk represents a significant difference (p < 0.05) between PC1 with P103 and PC1 without P103, as determined by Student's t-test.
