摘要 试验利用黑曲霉对黄曲霉毒素B1进行了降解率、活性组分的确定、安全性及对饲料中降解黄曲霉毒素效果的研究。研究结果表明,黑曲霉对黄曲霉毒素B1的降解率达93.28%,其中黑曲霉的胞外粗提液对黄曲霉毒素B1的降解活性最高,证明黑曲霉对黄曲霉毒素B1的降解是一种生物化学反应,黑曲霉发酵液对饲料中的黄曲霉毒素B1具有很强的降解作用。小鼠的急性毒理学试验证明,试验用黑曲霉本身具有良好的安全性。 The determination of degradation efficiency and active components of aflatoxin B1 safety and the effect of degradation aflatoxin in feed about the screened aspergillus was researched in this experiment used aspergillus niger. The result showed that the degradation of aflatoxin B1 by aspergillus niger was 93.28%, the degrading efficiencies of aflatoxin B1 by exocellular coarse extraction liquid was highest, and this proved that the degration of aflatoxin B1 by aspergillus niger was a biological reaction. The degrading effect of aflatoxin B1 in feed by aspergillus fermented liquid was strong. A favorable safety of aspergillus niger was testified through the acute toxicology experiments in mice.
