Enhanced Enzymatic Hydrolysis of Wheat Straw to Improve Reducing Sugar Yield by Novel Method under Mild Conditions

Wheat straw is a suitable source material for bioethanol production. Removing lignin and hemicellulose in wheat to improve enzymatic hydrolysis efficiency essential because of its complex structure. Deep eutectic solvents (DESs) have become substitutes ionic liquids (ILs), with the characteristics good biocompatibility, simple synthesis procedure low cost. However, process removing using present DESs requires high operation temperature or long time. Therefore, we studied novel method under mild conditions screening series based on an inorganic base remove straw. In this work, effect DES type, pH DESs, time enhancing hydrolysis, crystal structure chemical surface morphology were investigated. particular, Na:EG exhibited most excellent solubility conditions, 80.6% 78.5% hemicellulose, while reserving 87.4% cellulose at 90 °C 5 h, resulting 81.6% reducing sugar produced during 72 h. Furthermore, XRD, FT-IR SEM analysis verified removal. Hence, used will enhance thus promote industrial application produce bioethanol.
