黄曲霉毒素主要是由真菌寄生曲霉和黄曲霉产生的次生代谢产物,具有极强的毒性、致癌性,被认为是饲料和食品不可避免的污染物。对黄曲霉毒素污染的控制急需一种安全、高效、环保的脱毒方法。对比研究了柠檬酸、二氧化氯、霉立解以及饲用黄曲霉毒素B1分解酶对玉米样品中黄曲霉毒素降解脱毒效果的影响,结果表明,4种不同处理方法均对黄曲霉毒素具有降解效果,其中霉立解的效果最好。霉立解是枯草芽孢杆菌ANSB060的发酵液干燥后制成的黄曲霉毒素生物降解剂,具有较强的分解黄曲霉毒素B1的能力,可使玉米粉样品中的黄曲霉毒素B1的初始浓度为从356.66μg/kg降至16.83μg/kg ,降解率高达95.3%。
黃麯黴毒素主要是由真菌寄生麯黴和黃麯黴產生的次生代謝產物,具有極彊的毒性、緻癌性,被認為是飼料和食品不可避免的汙染物。對黃麯黴毒素汙染的控製急需一種安全、高效、環保的脫毒方法。對比研究瞭檸檬痠、二氧化氯、黴立解以及飼用黃麯黴毒素B1分解酶對玉米樣品中黃麯黴毒素降解脫毒效果的影響,結果錶明,4種不同處理方法均對黃麯黴毒素具有降解效果,其中黴立解的效果最好。黴立解是枯草芽孢桿菌ANSB060的髮酵液榦燥後製成的黃麯黴毒素生物降解劑,具有較彊的分解黃麯黴毒素B1的能力,可使玉米粉樣品中的黃麯黴毒素B1的初始濃度為從356.66μg/kg降至16.83μg/kg ,降解率高達95.3%。

Aflatoxins are the secondary metabolites mainly produced by Aspergillus f lavus and Aspergillus parasiticus with strong toxicity and carcinogenicity ,as unavoidable contaminants in feed and foods ,so an effective ,safe and environmentally method is urgently required for degrading aflatoxin .The degrading effects of four treatments including citric acid ,chlorine diox‐ide ,MLJ ,and a feed additive (aflatoxin B1‐detoxifizyme) on aflatoxins in corn were investigated .The results showed that :afla‐toxins were effectively degraded by the above four treatments ,in which the effect of MLJ was the best .MLJ was a aflatoxin bio‐degradation agent fermented by Bacillus subtilisANSB060 after drying ,and had the most effective degrading effect on aflatoxin B1 in corn ,with the content of aflatoxin B1 reduced from 356 .66 μg/kg to 16 .83 μg/kg ,and the degradation rate was 95 .3% .
