Peptide Mix from Olivancillaria hiatula Interferes with Cell-to-Cell Communication in Pseudomonas aeruginosa

Figure 1

Fourier transform infrared (FTIR) spectrum of the peptide mix isolated from Olivancillaria hiatula. Peak characteristics of the amide A and B bands (3100–3500 cm⁻¹), amide I band (1600–1700 cm⁻¹), amide II band (1480–1600 cm⁻¹), and amide III–VI bands (500–1300 cm⁻¹) have been shown, as described elsewhere [42, 43].
