  1. Lignin content (as Klason lignin) and monosaccharides from cellulase hydrolysis of eucalypt samples treated with M. thermophila laccase (10 U · g-1 and 50 U · g-1) and methyl syringate (MeS) mediator (1% and 3%) in a sequence including four enzymatic treatments (and four alkaline peroxide extractions) compared with a control without enzyme, a treatment with laccase alone, and the initial eucalypt wood. Means ± SD (from triplicates).
