With the increasing concern about the living surroundings and human health, the emissive volatile organic compounds (VOC), especially formaldehyde, during the production or use of wood composites has become the focus of attention. The promising future for wood composites might be the wood-based panels, which are formaldehyde-free and environmentally friendly made by enzyme engineering technology. The experimental materials in this study was composed of commercial laccase and wood which included the sapwood ...
