Comparison of thermostable enzymes in the liquefaction of high-solids lignocellulose. The effect of (A) endoglucanases Ta EGII/Cel5A and At EGV/Cel45A; (B) cellobiohydrolases At CBHI/Cel7A, Ct CBHI/Cel7A and Ta CBHI/Cel7A; (C) xylanases Ta XYL/Xyn10A and Nf XYL/Xyn11A; and (D) β-glucosidase At βG/Cel3A (3 mg enzyme of each per gram substrate dry matter) was studied with a viscosity of 15% w/w of hydrothermally pretreated wheat straw prepared in 0.05 mol/l sodium citrate buffer (pH 5.0) in a viscosity analyser (100 rpm, 50°C). For the reference solutions, the suspension was made up to the same solids content and incubated with mixing without enzyme addition.
