Table 1. MIC Values (μM) in P. aeruginosa ΔpvdFΔpchA Strain for Siderophores 2 and 4, Peptides 5–10, and Peptide–Siderophore Conjugates 11–34^a.

^aMIC values were determined after 24 and 48 h of growth and are the mean of three independent experiments. (l) = long peptide, 20–24 aa; (s) = short peptide, 11–12 aa; C/N = C- or N-terminal; and DS = disulfide. Generally, peptides are composed of l-amino acids; X_D indicates a d-amino acid peptide, and X_L indicates l-amino acids for discriminatory purposes. Values are given in μM, n = 3. A conversion of the MIC values to μg/mL can be found in Table S9.
