With separation and purification, four of antifungal
substances against A. flavus were obtained. By means of ESI-MS/CID analysis, their molecular weight was
determined as being 1030D, 1044D, 1058D, 1072D, and the amino acid component of the antifungal
substances were identified as being Asn-Tyr-Asn-Pro-Glu-Ser-Thr, which agreed with amino acid
sequence of bacillomycin D
