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

在观察到严重真菌毒素污染的泰国土壤中，为了发现微生物的代谢性解毒作用，对从泰国木薯农场分离的细菌和真菌进行了检查，以确定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。对泰国中部地区马、羊、猪粪便和从粪便中分离的厌氧菌对霉菌毒素的代谢活性也进行了检测，但未发现明显的代谢作用。在动物组织方面，各种动物的肝脏组织可能将黄曲霉毒素B2转化为B1。山羊的各种器官组织也被证明能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.
