Analysis of culture supernatants from S. plymuthica V4 wild-type and gene deletion mutants by HPLC/MSMS. Columns: S. plymuthica V4 variants ΔschE, ΔschF0, ΔschF3, ΔschH, ΔschI, and the wild-type strain. Rows: extracted ion count in million activity units for each siderophore: serratiochelin A and B (closed and open form), photobactin, aerobactin, and enterobactin
