Abstract
Even if it is well established that acetylation of wood by the use of acetic anhydride is able to impart a significant degree of decay resistance, more evidence is needed to understand the mechanisms by which acetylated wood is protected from fungal decay. The aim of this paper was to study if a standardised leaching procedure with water (EN 84) vs. no leaching affected the Postia placenta decay of acetylated samples. Three different acetylation levels (low, medium and high) were tested in addition to untreated Southern yellow pine as control. The samples were harvested at two different stages of fungal incubation; 4 and 28 weeks. We compared changes in mass loss, wood moisture content, fungal biomass measured indirectly as fungal DNA, plus a small gene expression screening including five different genes. Generally there were not any striking differences between the leached and the non-leached samples. For the acetylated samples a statistically significant difference in mass loss between leached and non-leached samples were found at low and medium acetylation level after 28 weeks. Wood moisture content differed significantly between leached and non-leached acetylated samples for low acetylation level after 4 weeks and for at low and medium levels after 28 weeks. The gene expression levels were generally significantly lower after 4 weeks compared to 28 weeks of incubation. After 28 weeks no significant difference was found between leached and non-leached acetylated samples for any of the measured genes.
