What molecular biology can tell us about the biodegradation of lignocellulose: the utilization of molecular techniques for the detection, identification and enhanced understanding of wood degrading organisms
2013 - IRG/WP 13-20528
Molecular techniques are now routinely used in the identification, detection and analysis of wood degrading organisms. An overview of some of the early work on nucleic acid isolation and characterization will be followed by a discussion of the power of sequencing and other procedures for better understanding: the mechanisms involved in the biological degradation of wood, the metabolic basis of pre...

Assessment of Scots pine sapwood susceptibility to moulds by determination of fungi growth and ergosterol content in infested wood
2014 - IRG/WP 14-20540
The susceptibility of wood to filamentous fungi (mould) attack is determine mainly by laboratory methods with descriptive grading of fungal growth on the surface of the wood specimens. It is a lot of different grading scale of fungi growth, but determination of the size of fungi growth is many times not easy, not clear and often difficult. Although the filamentous fungi are not included to microor...

Moisture content as a quality control parameter in thermally modified timber production
2017 - IRG/WP 17-20622
Quality assurance (QA) or factory production control (FPC) is necessary to ensure a proper production process. The requirements of QA/FPC can result from EN and national standards, quality assurance systems, or producer-specific rules.
TMT producers must ensure that the process was correct, and to ensure traceability of products. In addition to the electronic records, the material should be che...

Natural resistance of Bambusa vulgaris to termite and powder-post beetle attack in laboratory and graveyard tests
2018 - IRG/WP 18-10925
Deterioration is the major setback to the utilisation of bamboo products. To enhance bamboo utilization, an understanding of the level of resistance to degradation is important. In this study, level at which Bambusa vulgaris will naturally resistant attack by subterranean termites and powder-post beetles were evaluated. B. vulgaris aged 2, 3 and 4 years were subjected to attack by subterranean ter...

The anatomical determination of wood samples found in the “Fürstengräber” from Lübsow (Poland)
2018 - IRG/WP 18-10930
The paper presents the results of anatomical research identifying three wooden fragments from the “Princes Graves” (“Fürstengräber”) in Lübsow, Poland. The research demonstrates that the wooden fragments are typical of wood harvested from European forests.
The physicals conclusions are important for the research of Jan Schuster, from the University of Lodz, Institute of Archeology, Pol...

The Impact of Cryopreservation Techniques and of Water Quality on the Wood Degrading Ability of Fungal Strains: Recommendations for Maintenance and Culturing Procedures
2018 - IRG/WP 18-20636
In order to establish an optimal cryopreservation method, strains of Basidiomycete and Ascomycete fungi, which are among the most frequently used for wood durability testing, were evaluated using three cryopreservation procedures at -80°C. The main objective was to prevent decrease of the fungal virulence that may occur due to repeated routine sub-culturing procedures and to optimize the reactiva...

Color change of timber exposed outdoors - Influence of season exposure test starts
2019 - IRG/WP 19-40865
For the client the material and color of the exterior wall are important, because they affect the impression of the building [1]. However, discoloration of the exterior wall begins as soon as the building is completed, by various factors such as rainfall. We tried to quantitatively evaluate the changes of the exterior wood, and to organize the influences of climate conditions, in order to use the ...

Wood protection techniques and natural weathering: their effect on aesthetics and preference of people
2019 - IRG/WP 19-50351
Current research successfully contributes to improving wood protection techniques. However, the vast majority of research on preventing degradation of wood ignores a critical aspect of making successful products and processes – user selection of materials, which may largely depend on the aesthetical qualities. Wood treatments change the tactile and visual properties of wood substantially and the...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...
