 note = {Aflatoxin B_1 (AFB_1) is the most potent carcinogenic and toxic substance among many kinds of mycotoxins. We did screening for AFB_1 degradation activity from some edible mushrooms. When AFB_1 was incubated with culture medium of each edible mushroom at 30℃ for 5 days, amount of AFB_1 remarkably decreased; instead, another fluorescent substance was newly formed, which was placed under AFB_1 on thin layer chromatography plate. The same degradation activities were also observed when culture media of Pleurotus ostreatus strains were used. The AFB_1 degradation activity could be precipitated by 85% ammonium sulfate fractionation, indicating that a certain enzyme was likely involved in the degradation reaction., 食用きのこの培養上清についてアフラトキシンB_1(AFB_1) 分解試験を行った. きのこの培養ろ液を用いてAFB_1を30℃にて5日間処理したところ, 薄層クロマトグラフィーによりAFB_1の分解が確認され, 同時にAFB_1よりもRf値が小さい蛍光物質が生成された. AFB_1分解活性は特にPleurotus ostreatusから高頻度で検出された. P. ostreatusのAFB_1分解活性は硫酸アンモニウム沈殿や脱塩処理後も回収されたことから, 当該活性は培養上清中に含まれる酵素に由来するものと結論した.},
