Hydrolytic capacities of different lignin-enzyme complex. Hydrolysis of 1 % Avicel and 1 % cellobiose by lignin-CEL complex (a), lignin-Celluclast 1.5L complex (b) and lignin-Novozyme 188complex (c) in 50 mM sodium citrate buffer at pH 5.0 for 48 h. CEL composed of Celluclast 1.5L (22.7 mg/g lignin) and Novozyme 188 (11.1 mg/g lignin). The doses of Celluclast 1.5L and Novozyme 188 were 22.7 and 11.1 mg/g lignin, respectively.
