Abstract
In this study, aspen, yellow birch, and sugar maple samples were treated with four different fungi for 2, 4, and 8 weeks, for biological incising to improve wood permeability. The four fungal species were Ophiostoma piceae (wood staining fungus), Gliocladium roseum (mold fungus), Trametes versicolor, and Irpex lacteus (white-rot fungi). The fungal bio-incised wood samples and control samples not exposed to fungi were then impregnated with a low molecular weight phenol-formaldehyde (PF) resin and cured in an oven to improve wood hardness. The treated wood samples were tested for hardness according to European Standard EN 1534. Generally, bio-incising ...
