Although there are a lot of information about changes in lignin, carbohydrates, ash and lipophilic extractives
content of wood substrates by the fungal treatment (Ferraz et al. 2001, Hakala et al. 2004, Singh et al. 2010),
knowledge on its effect on wood transport capacity is lacking. Therefore, the ECCSA in the radial and tangential
direction of E. grandis wood slices corresponding to each treatment was estimated.
Figure 7 shows the ECCSA in the radial direction as a function of the distance from the external face of the wood
blocks. It can be observed that all fungal treatment increases the ECCSA in the radial direction, and it is more
notorious near the external surface of the samples. FBCC 313 showed the highest effect (ECCSA increased from
0.06 to 0.15 at the interface). However, no changes were found in tangential direction (data not shown).
