“…The preservation techniques that have been extensively studied for the protection of wooden products involve treatment with copper-amine-based wood preservatives (Humar et al, 2007;Humar et al, 2007;Humar and Lesar, 2008;Humar and Lesar, 2009). Additionally, veneers treated with CCA (chromated copper arsenate) have been inoculated with various monocultures and soil to determine how efficiently wood-inhabiting fungi can act on copper and remove it from the wood, under laboratory conditions (Sharp, 1975). To date, many stud-ies have been conducted on decay resistance with copper as the preservative ingredient (Ahn et al, 2008;Guillen et al, 2009).…”

To evaluate the resistance of wood to decay caused by fungi, sapwood and heartwood of red pine (Pinus densiflora) and sapwood and heartwood of larch (Larix kaempferi) were conducted. Wood samples were immersed for 96 h in pyroligneous liquor. Then, the brown-rot fungus, Fomitopsis palustris, was used to examine the decay resistance of red pine and larch. Weight and density of wood from the all conditions increased after immersion treatment. Weight loss after decay resistance test was also dropped with a immersion treatment. The lowest weight loss indicated at immersion-treated heartwood of larch. Immersion treatment using pyroligneous liquor effectively increased the resistance of wood to decay caused by fungi.

“…The soluble portion of copper compounds which remain undissolved act as a reservoir from which copper ions are released to the substrate (Sharp 1975;Richardson 1997;Pohleven et al 1999). Although the nature of the toxicity of copper to fungi is still not well understood, it is clear that copper must be dissolved in water to be delivered to the fungal spore or cell.…”

CopperCopper tolerance Copper resistance Wood preservation Wood-rotting fungi EPRThe tolerance of various fungi against copper was examined. For this purpose, we impregnated Norway spruce (Picea abies) specimens with two different aqueous solutions: copper(II) octanoate with ethanolamine or copper(II) sulfate (cCu = 1.0 6 10 -2 mol/l). Impregnated and unimpregnated test specimens were then exposed to brown rot fungi Antrodia vaillantii and Gloeophyllum trabeum or to white-rot fungi Schizophyllum commune and Trametes versicolor. After 2, 4, 6 and 12 weeks of exposure Electron Paramagnetic Resonance, Atomic Absorption Spectroscopy and mass loss measurements were performed. The results indicate that A. vaillantii, G. trabeum and T. versicolor transform copper(II) sulfate in wood into non-soluble, and therefore non-toxic, copper oxalate. The intensity of this reaction depends on the amount of excreted oxalic acid and was the highest for A. vaillantii and the lowest for T. versicolor. In the presence of ethanolamine, formation of insoluble copper oxalate was not possible and therefore, decay could not proceed. The major portion of copper remained in the wood and only minor amounts were in some cases translocated into nutrient media.
