Identification of fengycin homologues from Bacillus subtilis with ESI-MS/CID.


Bacillus subtilis fmbJ (CGMCC no.0943) was used to produce lipopeptides antibiotics fengycin. The fengycin mixture was precipitated with 6N HCl and extracted by methanol. Electrospray ionization mass spectrometry/collision-induced dissociation (ESI-MS/CID) were used to analyze the fengycin mixture. In the ESI-MS/CID spectra of fengycin molecular ions… (More)
