alternatively, when using 1 g of

wood particles
in 8 ml of 80% phosphoric acid pretreatment for
incubation with microwave irradiation for 20 sec and in
subsequent enzymatic hydrolysis 100 mg of left

of cellulose, of xylanase
and of laccase in 50 mM sodium acetate buffer, pH 5.0
for one day incubation. Water extractives,
p
-coumaric
acid, vanillic acid and ferulic acid in concentration-
dependent manner all inhibited on cellulase hydrolysis.
The negative effects of phenolic compounds overcome in
concentration-dependent manner when added laccase into
cellulose hydrolysis by cellulase. Laccase has a good
potential to decrease inhibitors in form of phenolic
compounds in wood extractives blocking cellulases
activity.
