镰刀菌属真菌侵染田间作物，引起真菌毒素污染，造成农产品的产量和品质损失。玉米赤霉烯酮(Zearalenone，Zen)是由几种镰刀菌产生的真菌毒素，是食品中常见的污染物，对食品安全构成极大的威胁。因此，人们研究了不同的策略来管理产毒病原体和霉菌毒素污染。近年来，生毒真菌生物防治成为一种环境友好的防治策略，而木霉是一种具有很大拮抗潜力的真菌属，可以控制产生真菌毒素的病原菌。本研究的主要目的是探索筛选出的木霉菌株对产Zen的禾谷镰刀菌的潜在作用，其次是研究不同木霉菌株对Zen的代谢活性。三个试验菌株被证明是潜在的防治Zen产生菌的候选菌株。此外，我们还首次报道了木霉将Zen转化为还原形式和硫酸化形式的能力，并提供了供试木霉不能通过糖基化来解毒Zen的证据。这为产锌真菌和木霉分离株之间的相互作用提供了更多的洞察力。
Fungi belonging to Fusarium genus can infect crops in the field and cause subsequent mycotoxin contamination, which leads to yield and quality losses of agricultural commodities. The mycotoxin zearalenone (ZEN) produced by several Fusarium species (such as F. graminearum and F. culmorum) is a commonly-detected contaminant in foodstuffs, posing a tremendous risk to food safety. Thus, different strategies have been studied to manage toxigenic pathogens and mycotoxin contamination. In recent years, biological control of toxigenic fungi is emerging as an environment-friendly strategy, while Trichoderma is a fungal genus with great antagonistic potentials for controlling mycotoxin producing pathogens. The primary objective of this study was to explore the potentials of selected Trichoderma isolates on ZEN-producing F. graminearum, and the second aim was to investigate the metabolic activity of different Trichoderma isolates on ZEN. Three tested Trichoderma isolates were proved to be potential candidates for control of ZEN producers. In addition, we reported the capacity of Trichoderma to convert ZEN into its reduced and sulfated forms for the first time, and provided evidences that the tested Trichoderma could not detoxify ZEN via glycosylation. This provides more insight in the interaction between ZEN-producing fungi and Trichoderma isolates.
