Capsule expression does not prevent bactericidal activity of peptides. Spores were grown for 4 h in MHB at 37°C in 5% CO2 and capsule expression was verified by India Ink exclusion (A) before being utilized in RDAs (B) in which the MEC of each peptide was determined against 2 × 106 Ames and UTA8 bacilli. Graph values represent the mean MEC calculated from four plates ± SEM. Unpaired, two-tailed Student’s t tests were used to determine statistical significance. **, p < 0.01.
