Barefoot-heat-impact of oil-heat-treated wood: An important thermal property of decking boards
2009 - IRG/WP 09-40458
In this study the phenomenon of sensual heat impression was examined, when walking with bare feet on sun exposed wood based decking boards. A suitable method for measuring the heat flux from decking boards into an artificial foot was developed. The method and measuring device is described as well as results from measuring three different decking board materials: Oil-heat-treated spruce (OHT), untr...

Adsorption of ACQ components in wood
2010 - IRG/WP 10-30522
To investigate the chemical adsorption capacity of copper-monoethanolamine (Cu-Mea) components on wood, the Na+ cation exchange capacity (CEC) of red pine (Pinus resinosa Ait.) was determined and compared to the adsorption capacity of free Mea and Cu-Mea complexes. The CEC increased with increasing pH. Free Mea adsorption as a function of pH followed the sodium adsorption curve except at pH over 9...

Impact of water holding capacity and moisture content of soil substrates on the moisture content of wood in terrestrial microcosms
2019 - IRG/WP 19-20662
Terrestrial microcosms (TMC) are frequently used for testing the durability of wood and wood-based materials as well as the protective effectiveness of wood preservatives. In contrary to experiments in soil ecology sciences, the experimental set-up is usually rather simple. However, for service life prediction of wood exposed in ground, it is of immanent interest to better understand the different...

Extraction, identification and antifungal activity of polar extractives originated from various wood species
2020 - IRG/WP 20-20673
Extractives are non-cell wall small molecules present in wood and other lignocellulosic materials that can be removed by solvents. Although they represent a minor fraction in comparison with the structural cell wall components, they are an important source of functional groups or molecules with bioactivity or antioxidant properties, that could be used in medicine, cosmetic or wood preservation. T...

Decay capacity and degradation patterns of Xylaria hypoxylon on different wood species
2022 - IRG/WP 22-10985
A host of physical and environmental factors may influence fungal decay including the wood substrate, temperature, moisture, oxygen, light, pH, and nitrogen. Understanding the effects of these factors on fungal decay is important for the effective utilization of wood decay fungi in biotechnological processes and for understanding the role of these organisms in global carbon cycling. The ascomycete...

A novel cellulose-binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11019
Wood-rotting basidiomycetes are the major organisms decomposing wood in nature. They are classified into two groups based on their decay modes; white-rot fungi and brown-rot fungi. White-rot fungi secrete various cellulolytic enzymes during the wood degradation process. The enzymes are known to be often appended with a cellulose binding domain (CBD) which assists the activity of catalytic domain. ...

The cellulose binding mechanism of a novel cellulose binding domain from the brown-rot fungus Gloeophyllum trabeum
2023 - IRG/WP 23-11021
In nature, wood decay is caused by various wood-rotting basidiomycetes. Wood-rotting basidiomycete are mainly divided into white-rot fungi and brown-rot fungi. Their main carbon source is cellulose of the wood cell wall during wood decay, and they produce a variety of enzymes to decompose cellulose. The cellulolytic enzymes often possess a cellulose binding domain (CBD) as an additional domain con...
