Title: (EN) Organic solvent pretreatment of biomass to enhance enzymatic saccharification
(ZH) 用有机溶剂预处理生物质以促进酶解糖化
Abstract:
(EN) Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of ammonia and optionally an additional nucleophile to fragment and extract lignin without loss of hemicellulose. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation.
(ZH)

使用有机溶剂溶液在碱性条件下预处理生物质,所述溶液中存在氨和任选地一种附加的亲核物质以在不损失半纤维素的情况下破碎并萃取木质素。用糖化酶聚生体进一步水解预处理的生物质。可利用糖化释放的可发酵糖发酵生产目标化学制品。
