In this study, the degradation and bio-conversion of Dioscorea zingiberensis C. H. Wright solid residues (DZWSR) were performed. A large number of solid residues from Dioscorea zingiberensis C. H. Wright (DZW) are discarded or burned directly in the diosgenin industry, resulting in a serious waste of resources and environmental pollution. After dilute acid impregnation with low-pressure steam expansion (DALPSE), organic solvent extraction, enzyme hydrolysis, and other treatments, the hemicellulose degradation rate reached 94.71 %, the cellulose...
