Rubberwood Fiber Treatment by Laccase Enzyme and Its Application in Medium Density Fiberboard

In this work physico-chemical properties of rubber wood fiber were analyzed after laccase treatment and evaluated the performance of medium density fiberboard (MDF) fabricated from the treated fiber. In a single parameter study, two different times i.e. 60 min and 120 min of laccase treatment were a...
