IMPROVED METHOD FOR BIOLOGICAL PRETREATMENT OF WOOD CHIPS

摘要

The present invention comprises a method for altering the structure or composition of wood which method comprises adding to compressed wood a medium comprising a structure-altering or composition-altering effective amount of at least one fungi or bacteria, one or more culture products thereof, such as enzymes, one or more substances obtained therefrom, one or more enzymes from non-microbial sources, or combinations thereof, to produce inoculated wood upon decompression. Compression of the wood substrate prior to or during application of the biological agent introduces fractures in the wood substrate thereby allowing the biological agent to penetrate the wood structure. Furthermore, the biological agent is drawn into the wood substrate as the wood re-expands during decompression.
