Exploring the effect of bacterial cell density on the PapR7-derived peptide combinations activity. β-galactosidase activity of Bt A’Z induced by the addition of 10 μM PapR7-derived peptides normalized to untreated bacterial cells at end lag phase of bacterial growth (OD600 of 0.1 ± 0.03; mean ± SEM, n = 9). *p < 0.01 indicates a statistically significant difference between untreated Bt A’Z and addition of PapR7-derived peptides. Different letters indicate statistically significant differences between PapR7-derived peptide treatments (p < 0.01).
