High concentrations of ochratoxin A (OTA) in feed lead to growth depression in animals. It has been reported that binders can be used for deactivating aflatoxins but not for other mycotoxins without negatively influencing the animals health. In this study a strain from the genus ofTrichosporon with the ability to cleave ochratoxin A very selectively into phenylalanine and the non-toxic ochratoxin α (OTα) could be isolated. This strain was selected from a pool of OTA detoxifying microorganism by carrying out several investigations.Trichosporon sp. nov. can be fermented and stabilized. In a feeding trial with broilers lyophilizedTrichosporon-cells could compensate performance losses caused by OTA.
高浓度的赭曲霉毒素 A（OTA）在饲料中会导致动物生长抑制。据报道，黏合剂可用于使黄曲霉毒素失活，但不能用于其他霉菌毒素，而不会对动物健康产生负面影响。在这项研究中，从一种能够非常选择性地将赭曲霉毒素 A 切割成苯丙氨酸和无毒的赭曲霉毒素α（OTα）的曲霉菌属中分离出一种具有这种能力的菌株。该菌株是通过进行多项研究从 OTA 解毒微生物池中选择出来的。可以发酵和稳定地生产新型曲霉菌。在一项肉鸡饲养试验中，冻干的新型曲霉菌细胞可以补偿由 OTA 引起的生产性能损失。
