英文摘要in recent years, bacillus species have received considerable attention for the biological control of many fungal diseases. in this study, bacillus amyloliquefaciens q-426 was tested for its potential use against a variety of plant pathogens. our screen for genes involved in the biosynthesis of antifungal agents revealed that the fen and bmy gene clusters are present in the q-426 genome. lipopeptides such as bacillomycin d, fengycin a, and fengycin b were purified from the bacterial culture broth and subsequently identified by esi-mass spectrometry. the minimal inhibitory concentration of fengycin a against fusarium oxysporum f. sp. spinaciae w.c. snyder & h.n. hansen o-27 was determined to be 31.25gml(-1). however, exposure of fungal cells to 50gml(-1) of fengycin a did not allow permeation of fluorescein diacetate into the cytoplasm through the cell membrane. moreover, leakage of intracellular inorganic cations, nucleic acid and protein were also not detected, indicating that the fungal cell membrane is not the primary target of action for fengycin a. profound morphological changes were observed in the f. oxysporum strain and spore germination was completely inhibited, suggesting that 50gml(-1) of fengycin a acts, at least, as a fungistatic agent.
