Fig. 2From: Lignin from hydrothermally pretreated grass biomass retards enzymatic cellulose degradation by acting as a physical barrier rather than by inducing nonproductive adsorption of enzymesGlucose release from 2% DM Avicel hydrolysis after adsorption experiment of Cellic® CTec3 in the presence of lignin-rich residues (LRRs) as in Experiment I (a–c) or by supernatant containing unbound enzymes after incubation with LRRs in Experiment II (d–Pyrolysis-GC–MS characterization of forage materials). LRRs were isolated from corn stover (L-CS) (a and d), Miscanthus × giganteus stalks (L-MS) (b and e), and wheat straw (L-WS) (c and f) that were hydrothermally pretreated at severity factors (log R0) 3.65 and 3.97. Data points represent average and standard deviation from two replicatesBack to article page
