Abstract
The effects of three different fungal treatments on several technology characteristics of Eucalyptus grandis wood, were studied
on industrial chips and blocks. The percentage of the substrate mass loss by the fungal treatment, and the relative amount of
extractives and lignin were determined. The effective capillarity of wood, pH and total reducing sugars concentration in watersoluble
fraction (WSF) were also determined. There was a reduced mass loss of the substrate by the fungal treatment (less than
3%). Gelatoporia subvermispora FBCC 313 showed the highest reduction in the Klason lignin content, the highest
endoglucanase activity on the WSF as well as the highest ability to increase the effectively capillarity in the radial wood
direction. This last effect is interesting since it might facilitate the wood impregnation processes and therefore to reduce the
consumption of reagents in industrial treatments.
