Unraveling the effects of laccase treatment on enzymatic hydrolysis of steam-exploded wheat straw

Abstract Laccase enzymes are promising detoxifying agents during lignocellulosic bioethanol production from wheat straw. However, they affect the enzymatic hydrolysis of this material by lowering the glucose recovery yields. This work aimed at explaining the negative effects of laccase on enzymatic hydrolysis. Relative glucose recovery in presence of laccase (10 IU/g substrate) with model cellulosic substrate (Sigmacell) at 10% (w/v) was almost 10% points lower ( P
