摘要: The recalcitrance of lignocelluloses toward enzymatic hydrolysis necessitates pretreatments. Ionic liquid pretreatment with 1-allyl-3-methylimidazolium chloride ([amin]Cl) was applied to risk husk and cellulose-containing fractions were recovered from the ionic solutions by acidic, alkaline, alkaline–acidic regeneration respectively. Enzymatic materials carried out results demonstrated that: (i) acidic not substantial ensure enhanced digestibility; (ii) alkaline increased hydrolysis; (iii) led an almost complete carbohydrate fraction. obtained rationalized means chromatographic analyses soluble collected after different processes: removal hemicellulose, which going regeneration, seemed play a crucial role in enhancing rice saccharification.
