黄曲霉毒素是某些黄曲霉和寄生曲霉产生的一种肝毒素,对动物有极强的毒性和致癌性。其毒性比已知的致癌物质二甲基亚硝酸的毒性高75倍。黄曲霉毒素能引起试验动物致癌已成定论〔1〕。分子遗传学分析表明,黄曲霉与寄生曲霉毒素生物合成涉及25个相关结构基因〔2〕。研究表明,这些
Aflatoxins are hepatotoxins produced by certain Aspergillus flavus and Aspergillus parasiticus and are extremely toxic and carcinogenic to animals. It is 75 times more toxic than the known carcinogen dimethylnitrite. Aflatoxin can cause cancer in experimental animals has become a definite conclusion (1). Molecular genetic analysis showed that A. flavus and parasitic astaxanthin biosynthesis involved 25 related structural genes [2]. Research shows that these
