The study on mycotoxin detoxification and protection of animal mycotoxicoses in Thaoland.

为了发现泰国土壤中微生物的代谢解毒作用，在那里已经观察到真菌毒素的严重污染，从泰国木薯农场分离的细菌和真菌被检查了它们代谢黄曲霉毒素、赭曲霉毒素A和玉米赤霉烯酮的活性。结果表明，部分细菌和真菌对黄曲霉毒素B1和赭曲霉毒素A有代谢作用。还对生活在泰国中部地区的马、羊和猪的粪便以及从粪便中分离出的厌氧菌进行了检查，以确定它们对霉菌毒素的代谢活性，但未发现明确的代谢。关于动物组织，建议各种动物的肝组织可能将黄曲霉毒素B2转化为B1。山羊的各种器官的组织也被证明可以将玉米赤霉烯酮代谢为α-和β-玉米赤霉烯醇。

In order to find metabolic detoxification by micro-organisms in soil of Thailand, where heavy contamination with mycotoxins has been observed, bacteria and fungi isolated from Cassava farms in Thailand were examined for their activities to metabolize aflatoxin, ochratoxin A and zearalenone. The result demonstrated some bacteria and fungi to metabolize aflatoxin B1 and ochratoxin A. Feces of horse, sheep and pig living in the central region of Thailand, and anaerobic bacteria isolated from the feces, were also examined for their metabolic activities toward mycotoxins, but clear metabolism was not found. With regard to animal tissues, a possible conversion of aflatoxin B2 to B1 by the liver tissues from various animals was suggested. Also tissues of various organs of goat were demonstrated to metabolize zearalenone to alpha-and beta-zearalenols.
