Abstract: The biotechnological application of the white rot fungus Physisporinus vitreus named ''bioincising'' is currently being investigated for permeability improvement of Norway spruce (Picea abies (L.) Karst.) wood. During short-term (-9 weeks) incubation, fungal activity induces degradation of pit membranes and a simultaneous alteration of the tracheid cell wall structure. In Part 1 of this article series, the occurrence of selective delignification and simultaneous degradation was shown by UV-microspectrophotomet… Show more

“…The reproducibility of this method proved to be low due to the heterogeneity of the cell wall, which is changing during degradation. An in-depth analysis of chemical alterations induced by the enzymatic activity of P. vitreus will be the subject of the second article of this series (Lehringer et al 2011).…”

“…Moreover, the applicability of the nanoindentation technique on decayed wood should be assessed during short-term incubation times. An in-depth chemical analysis of changes in chemical composition due to fungal activity will follow in a second article of this series (Lehringer et al 2011). …”

“…This is confirmed by DVS test results, i.e., the higher sorption capacity of the fungal treated wood after RH exceeded, e.g., 75%. Degradation of cellulose fibrils in the cell walls of fungal treated wood for periods longer than 8 weeks (Lehringer et al 2011b) can be another explanation for the improved dimensional stability of the modified wood.…”

“…The mechanical parameter that reflects most sensitively these changes is tensile strength parallel to the grain (Ifju, 1964;Evans and Banks, 1990; Derbyshire and Miller, 1981; Derbyshire et al, 1996). It was demonstrated by numerous experiments that the tensile strength may precisely reflect the chemical changes of wood constituents due to exposure to biodegradation, acid conditions or weathering (Razckowski, 1980 Lehringer et al, 2011). In order to record the fine changes, which are restricted either to a shallow surface layer or their distribution in depth of the sample, the microtensile testing technique can be successfully applied to various kinds of modification processes (Jirouš Rajković et al, 2004;Turkulin et al, 2006, Xie et al, 2007.…”
