Fig. 2From: Performance of three delignifying pretreatments on hardwoods: hydrolysis yields, comprehensive mass balances, and lignin propertiesEnzymatic hydrolysis glucose yields for pretreated solids of hybrid poplar (a and b) and eucalyptus (c and d) prepared by Cu-AHP, CELF, and [Ch][Lys] pretreatments as a function of enzyme loading (mg protein/g glucan in pretreated solids) and hydrolysis time. Enzymatic hydrolysis was performed at a 10% (wt/vol) solids loading with the pH buffered at 5.0 for 24 or 72 hBack to article page
