【摘要】 取自然条件下污染黄曲霉毒素B1的玉米、豆粕和花生粕饲料进行解毒试验。每种饲料选择3个黄曲霉毒素B1浓度(10.7~62.2μg/kg),按11‰比例加入糙皮侧耳浓缩发酵液,72 h降解率为39.5%~55.4%,168 h降解率为52.4%~75.5%。在模拟牛胃条件下,以豆粕饲料含不同浓度的黄曲霉毒素B1(15.7μg/kg、30.5μg/kg和48.9μg/kg)为有毒源,糙皮侧耳浓缩发酵液添加11‰,24 h解毒率为25.5%、19%和17.4%,48 h解毒率为42.7%、33.1%和29%。改变浓缩发酵液添加比例为7‰、9‰、11‰、13‰和15‰,降解时间36 h,解毒率为53.5%以下。

【Abstract】 The materials for the AFB1toxicity-degradation test were natural AFB1 of corn,bean cake and peanuts cake feed,the three AFB1concentrations( from 10. 7 to 62. 2μg / kg) were studied from every feed,taking the weight of the feed as the base,add to 11‰Pleurotus Ostreatus concentrated fermentation. The rate of AFB1-degradation increased from 39. 5% to 55. 4% when 72 hours; the rate of AFB1- degradation increased from 52. 4% to 75. 5% when 168 hours. In imitate of the stomach of ox test,the test material was bean cake containing AFB1 with different coucentrations such as 15. 7 μg / kg,30. 5 μg / kg and 48. 9 μg / kg,taking the weight of the feed as the base,11% Pleurotus Ostreatus concentrated fermentation added,the rate of AFB1-degradation are 25. 5%,19% and 17. 4% when 24 hours respectively,the rate of AFB1-degradtion are 42. 7%,33. 1% and 29% when 48 hours respectively,add to proportion of Pleurotus Ostreatus concentrated fermenta tion are 7‰,9‰,11‰,13‰ and 15‰,the rate of AFB1-degradation are at 53. 5% when 36 hours.
