Abstract: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 effects 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 Armillaria 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-liquid 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 degradation 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 increased 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.
