枯草芽孢杆菌产生伊枯草菌素组的肽脂质化合物，其已显示具有抗真菌特性，但并非所有真菌物种对这些化合物敏感。 在这项研究中，活性iturin A，产生的B。枯草杆菌菌株B-3。 将浸渍有不同浓度伊枯草菌素A的纸盘置于接种有镰刀菌属、Gerlacia、青霉菌属或曲霉属的产芽孢物种的分生孢子的琼脂平板上。 大多数分离物在伊枯草菌素A浓度低至4 μ g/盘时被抑制。 意大利青霉（Penicillium italicum）、葡萄青霉（P. vietiatum）、A. ochraceus和A. iturin对杂色曲霉的抑制作用最强，而桔黄青霉和A.寄生蜂对伊枯草菌素A的敏感性最低。
Bacillus subtilis produces peptidolipid compounds of the iturin group that have been shown to have antifungal properties, but not all fungal species are sensitive to these compounds. In this study, the activity of iturin A, produced by B. subtilis strain B-3, was tested. Paper disks impregnated with various concentrations of iturin A were placed on agar plates seeded with conidia of toxigenic species of Fusarium, Gerlacia, Penicillium or Aspergillus. Most isolates were inhibited at iturin A concentrations as low as 4-mu-g/disk. Penicillium italicum, P. viridicatum, A. ochraceus and A. versicolor were most strongly inhibited by the iturin whereas P. citrinum and A. parasiticus were least sensitive to iturin A.
