摘　　要：以蜜环菌Am⁃07⁃22为发酵菌株,以玉米皮和玉米黄粉为主要研究对象,以玉米赤霉烯酮的降解率为指标,考察不同发酵时间、发酵温度、料液比、接种量对玉米皮和玉米黄粉中玉米赤霉烯酮降解率的影响,并研究蜜环菌Am⁃07⁃22对玉米皮和玉米黄粉不同比例混合物的毒素降解效果及产物中蛋白质和多糖的含量变化。结果表明:蜜环菌降解玉米皮中玉米赤霉烯酮的最佳条件为发酵温度27℃、料液比1∶1.5(g/mL)、接种量10%,玉米赤霉烯酮的降解率为93.63%,蜜环菌降解玉米黄粉中玉米赤霉烯酮的最佳条件为发酵温度27℃、料液比1∶2(g/mL)、接种量12.5%,玉米赤霉烯酮的降解率为96.60%。蜜环菌Am⁃07⁃22固态发酵不同质量比的玉米皮、玉米黄粉(1∶1、1∶2、2∶1)中玉米赤霉烯酮的降解率分别为95.93%、96.62%和96.97%,质量比为2∶1的玉米皮、玉米黄粉中蛋白质和多糖含量提高,分别提高91%和52%。蜜环菌Am⁃07⁃22不仅对玉米加工副产物中玉米赤霉烯酮有良好的降解效果,同时提高产物中蛋白质和多糖含量。Armillaria mellea 07⁃22 was used as the fermentation strain,corn husk and corn gluten meal were the main research objects,and the degradation rate of zearalenone was used as the index to investigate the ef⁃fects of different fermentation time,fermentation temperature,material⁃liquid ratio,and inoculation amount on the degradation rate of zearalenone in corn husk and corn gluten meal.The toxic degradation effect of Armil⁃laria mellea 07⁃22 on the mixtures of corn husk and corn gluten meal with different proportions and the changes in protein and polysaccharide contents of the product were also studied.The results showed that the optimal conditions for Am⁃07⁃22 to degrade zearalenone in corn husk were a fermentation temperature of 27℃,a material⁃liquid ratio of 1∶1.5(g/mL),and an inoculation amount of 10%,achieving a degradation rate of 93.63%.For corn gluten meal,the optimal conditions were a fermentation temperature 27℃,a material⁃liq⁃uid ratio of 1∶2(g/mL),and an inoculation amount of 12.5%,resulting in a degradation rate of 96.60%.In solid⁃state fermentation of different mass ratios of corn husks and corn gluten meal(1∶1,1∶2,2∶1),the deg⁃radation rates of zearalenone by Armillaria mellea 07⁃22 were 95.93%,96.62%and 96.97%,respectively.The protein and polysaccharide contents in corn husk and corn gluten meal with the quality ratio of 2∶1 in⁃creased most significantly by 91%and 52%,respectively.Armillaria mellea 07⁃22 not only exhibited excellent degradation capabilities for zearalenone in corn processing by⁃products,but also improved the protein and polysaccharide content in the resulting products.
