Detection of bioactive peptides produced by B. pumilus. (A–C) MALDI-TOF mass spectra of surface extracts of B. pumilus DSM 27T (type strain) (A); Abi11 (B) and Rs-Ts276 (C). MALDI-TOF mass spectra of the culture supernatant of B. pumilus Rs-Ts276 grown in the Landy-medium for 24 h at 30°C (D) and of a surface extract of the cell pellet obtained after 72 h (E). (F) MALDI-TOF mass spectrum of the pumilacidin-complex produced by Abi11. C15–C19 pumilacidins were detected.
