a Growth curve of S. pneumoniae D39 parent strain and ∆amiC mutant. Growth was measured in peptide-free chemically defined medium (CDM) in the presence and absence of 0.5 mg/ml peptide V11A by measuring optical density OD (450 nm) over time. Results represent three independent experiments, error bars indicate SEM. b, c Microscopy images of S. pneumoniae after incubation with FITC-labelled peptide V11A for D39 parent strain (b) and ∆amiC mutant (c). Representative images were taken at mid-bacterium localization in the z position showing FITC and Brightfield (BF) channels. Scale bar indicates 2 µm for all pictures in (b) and (c).
