Abstract

[Objective ] This study aims to determine the optimal solid-state fermentation conditions for the removal of zearalenone (ZEN ) from corn gluten feed by Aspergillus niger (A.niger ) FS10.[Method ] With the removal rate of ZEN as the indicator,single-factor experiments and response surface method were employed to optimize the key fermentation parameters (inoculation volume-to-mass ratio,fermentation temperature,fermentation duration,and solid-to-liquid ratio ).Furthermore,changes in mass fractions of key nutritional components in corn gluten feed before and after solid-state fermentation under the optimal conditions were analyzed.[Result ] The optimal fermentation conditions were established as follows:an inoculation volume-to-mass ratio of 120 μL∶1 g,a fermentation temperature of 26 ℃,fermentation duration of 5.5 d,and a solid-to-liquid ratio of 1 g∶1.4 mL.Under these conditions,the removal rate of ZEN reached (70.04±1.88)%.The mass fraction of crude protein in corn gluten feed increased from (19.92±0.20)% before fermentation to (21.94±0.42)% after fermentation,while the mass fraction of total amino acids rose from (16.240±0.165)% to (18.510±0.034)%.[Conclusion ] A.niger FS10 not only efficiently removes ZEN from corn gluten feed but also enhances its nutritional value as animal feed.The findings provide a scientific basis for the sustainable utilization and exploitation of corn gluten feed despite ZEN contamination.
