The novelty of the research consists in fact that decayed wood was taken from an old icon, on which several consolidation treatments were applied, and improvement indices (by Anobiidae insects) also determined. This investigated two types most used consolidant (Paraloid B72 10% Regalrez 1126 25%) solubilized three solvents, to improve properties lime samples coming cultural heritage objects pre...

Serpula himantioides is a wood-decaying fungal pathogen which widespread and causes potentially serious butt rot in living trees of numerous coniferous plantation species. This study aimed to quantify S. the wood Sawara cypress (Chamaecyparis pisifera) with using real-time polymerase chain reaction (real-time PCR). Species–specific primers were designed for internal transcribed spacer 2 (ITS2) ...

Accumulation of oxalic acid (OA) by brown-rot fungi and precipitation of copper oxalate crystals in wood decayed by copper-tolerant decay fungi has implicated OA in the mechanism of copper tolerance. Understanding the role of OA in copper tolerance is important due to an increasing reliance on copper-based wood preservatives. In this study, four copper-tolerant brown-rot fungi were evaluated fo...

One of the main objectives of thermal modification is to increase the biological durability of wood. In this study the fungal resistance of Norway spruce and Scots pine, thermally modified at 1958C and 2108C, was studied with a lap-joint field test. Untreated pine and spruce and pine impregnated with tributyl tin oxide (TBTO) and copper, chromium and arsenic (CCA) were selected as reference mat...

Hundreds of wood-inhabiting fungal species are now threatened, principally due to a lack of dead wood in intensively managed forests, but the consequences of reduced fungal diversity on ecosystem functioning are not known. Several experiments have shown that primary productivity is negatively affected by a loss of species, but the effects of microbial diversity on decomposition are less studied...

Three expedition huts in the Ross Sea region of Antarctica, built between 1901 and 1911 by Robert F. Scott and Ernest Shackleton, sheltered and stored the supplies for up to 48 men for 3 years during their explorations and scientific investigation in the South Pole region. The huts, built with wood taken to Antarctica by the early explorers, have deteriorated over the past decades. Although Ant...

In this study, we set up a wood decomposition experiment to i) quantify the percent of mass remaining, decay constant and performance strength of aspen stakes (Populus tremuloides) in dry and moist boreal (Alaska and Minnesota, USA), temperate (Washington and Idaho, USA), and tropical (Puerto Rico) forest types, and ii) determine the effects of fragmentation on wood decomposition rates as relat...

INTRODUCTION Transition state metals, such as manganese (Mn) and iron (Fe), have been reported to be involved in fungal degradation of wood (Ellis, 1959; Shortle and Shigo. 1973; Blanchette, 1984; Glenn et al., 1986). Manganese is also involved in the enzymatic degradation of lignin model compounds by the white-rot fungus Phanaerochaete chrysosporium Burds. (Tien and Kirk, 1984; Glenn et al., 1...
