Strain B-FS01, isolated from rape (Brassica napus) stem infected by Slerotinia sclerotiorum and identified as Bacillus subtilis, exhibited predominantly antagonistic activities against Fusarium moniliforme Sheldon ATCC 38932. Antifungal active compounds (AAC) were isolated and purified from the cultures of strain B-FS01 against ATCC 38932. The HPLC/electron spray ionization/collision-induced dissociation mass spectrum of AAC revealed a cluster of fengycin homologues containing fengycins A, fengycins B and a new type of fengycin. Further toxic assay of AAC in vitro against F. moniliforme indicated that AAC could strongly inhibit the growth of both mycelia and spores. In addition, treatment with AAC significantly modified the maize seed infection by ATCC 38932.
