一种生物降解脱氧雪腐镰刀烯醇的方法
摘要：
本发明公开了一种生物降解脱氧雪腐镰刀烯醇的方法，属于微生物技术领域和食品安全技术领域。本发明的降解脱氧雪腐镰刀烯醇的微生物是从太湖湖底泥中经梯度稀释分离、筛选得到的，经鉴定为青霉JS2(Penicillium sp.JS2)，在培养基中，DON的初始浓度为2mg/L，pH 6.0，经32‑35℃培养96h，DON的降解率为62％。该菌种降解呕吐毒素的稳定性很好，在培养基中，传代培养5代，DON的降解率均在60％以上。
摘要（英）：

The invention discloses a method for biodegrading deoxynivalenol (DON), and belongs to the technical field of microorganism and the technical field of food safety. The method is characterized in that the microorganism for degrading deoxynivalenol is obtained from bottom sludge of Taihu Lake through gradient diluting, separating and screening, and the microorganism is identified as JS2 (Penicillium sp.JS2); the initial concentration of DON in a culture medium is 2mg/L, and the pH is 6.0; after the DON is cultured for 96 hours under 32 to 35 DEG C, the degrading rate of the DON is 62%. The method for degrading vomitoxin through strains is high in stability; when the five generations are gained by serial sub-cultivation in the culture medium, the degrading rate of the DON is more than 60%.
