中文摘要：禾谷镰刀菌会导致小麦赤霉病，造成小麦品质和产量的损失。本文研究了芽孢菌毒素D（BD）抑制麦粒贮藏期禾谷镰刀菌生长和降低脱氧雪腐镰刀菌烯醇浓度的作用。研究发现，BD（75μg/mL）的添加显著抑制了禾谷镰刀菌的生长量，并使得DON浓度降低至47.5%-71.5%。表明BD可能是一种前景广阔的天然杀真菌剂，并且可能在减少食物和饲料中霉菌毒素方面具有应用潜力。
外文摘要：Fusarium graminearum causes Fusarium head blight, which leads to the quality and yield loss of wheat. In the present work, the inhibition effects of bacillomycin D (BD) on the growth of F graminearum and reduction of deoxynivalenol (DON) production in wheat grain storage were investigated. The hyphal growth and sporulation of F graminearum were restrained dramatically in the presence of 75 mu g/mL BD, and the inhibition rate reached to 94.6% and 97.5%, respectively. Ultrastructural observation of the hyphae showed BD caused stripping of F graminearum hyphal surface and destroying of the cellular structure. Furthermore, BD could lower the free fatty acid value and total antioxidant capacity and delay the decline of wheat quality, then exhibit an effective protection for wheat infection by F graminearum. BD could effectively inhibit mold growth and DON production during wheat seeds storage, thus enhancing the quality and shelf life of the kernel. The addition of BD (75 gig wheat) remarkably inhibited the amount of F. graminearum growth, and reduced the DON production to 47.5-71.5%. These results indicated that BD might be a promising natural and effective fungicide, and would have potential for reducing mycotoxins in food and feed.
