Fig. 4From: THF co-solvent pretreatment prevents lignin redeposition from interfering with enzymes yielding prolonged cellulase activityProtein adsorbed per gram of residual dry solids containing mostly K-lignin resulting from complete enzymatic hydrolysis of DSA and THF-washed DSA-pretreated switchgrass at 10Â g/L glucan loading, and CELF-pretreated switchgrass at 40Â g/L glucan loading. Initial protein added in all cases was 1.72Â g/LBack to article page
