Zearalenone (ZEN) is a non-steroidal estrogen produced by many Fusarium species in cereals and other plants, and is frequently implicated in safety of foods and feeds. A ZEN-degrading microorganism has been isolated and identified as a Bacillus subtilis subspecies. It degraded 99% ZEN (1 mg kg(-1)) in liquid medium after 24 h and more than 95% of ZEN (0.25 mg kg(-1)) could be degraded after 48 h in a solid-state fermentation. This isolate can thus be used to decontaminate raw materials, like grains, to reduce the mycotoxin concentration.
玉米赤霉烯酮（ZEN）是一种由多种镰刀菌在谷物和其他植物中产生的非甾体雌激素，经常与食品和饲料的安全性有关。已经分离出一种能够降解玉米赤霉烯酮的微生物，并将其鉴定为枯草芽孢杆菌亚种。该菌在液体培养基中 24 小时可降解 99%的 ZEN（1mgkg(-1))，在固态发酵 48 小时后可降解超过 95%的 ZEN（0.25mgkg(-1))。因此，该分离株可用于对谷物等原材料进行脱毒，降低真菌毒素浓度。
