Detection of Wood Destroying Fungi Using DNA Microarray Technology
2010 - IRG/WP 10-20435
Wood decay fungi of the phylum Basidiomycota cause serious damage to wooden constructions and building elements. The elimination and the appraisement of fungal decay require an assured species identification. Conventional fungal diagnostics are mainly based on morphological characteristics by macro- and microscopy analysis. For some years, standardised and highly sensitive molecular methods focuss...

Extraction and analysis of DNA from green and seasoned timber as basic methods for determination of wood species and origin
2013 - IRG/WP 13-20523
Against the background of the European timber trade regulation EUTR, commenced to law by March 2013, the determination of wood species and tracing of its origin is getting a great importance. A promising approach for establishing fast and reliable tracking systems for wood products is DNA analysis. A critical point is the extraction of analysable DNA from the wood and its lignified cell walls. Thu...

Virulence of two Laboratory Test Strains and one Natural Isolate of Rhodonia (Oligoporus) placenta against Thermally Modified Pine and Beech Wood
2013 - IRG/WP 13-20524
Rhodonia (Oligoporus) placenta is known as a relative aggressive basidiomycete fungus against thermally modified timber. In durability lab tests, this often results in a lower durability class, compared to other test fungi. In the reported work, the virulence of three different strains of Rhodonia placenta for untreated and thermally modified timber was determined and compared. Therefore, two lab ...

Real-Time PCR Assays for the detection of the dry rot fungus Serpula lacrymans and its close relative Serpula himantioides
2016 - IRG/WP 16-10867
Prevention of wood decay by fungi of the phylum Basidiomycota is an important issue of wood protection. The most destructive fungus in buildings in Central Europe is the dry rot fungus Serpula lacrymans, which needs more extensive restauration measures than all other wood decay fungi. Its close relative S. himantioides occurs more frequently in outdoor environment. The assessment and remediation o...

Development of procedures for sampling, testing, and classification to determine the biological durability of wood and wood products
2020 - IRG/WP 20-20676
This paper informs about a research project, which deals with several shortcomings and a lack of clarity within EN 350:2016. The project started in January 2020, will run for 3 years, and is operated by the Institute of Wood Technology Dresden (IHD) and the University of Goettingen (UGOE). Determination and classification of durability of wood and wood products against wood-destroying organisms ...

Development of a new method for wood hydrophobizing and fixation of copper compounds by chemical hardening of vegetable based modified oils
2016 - IRG/WP 16-40754
Wood products with ground and direct water contact, but without sufficient biological durability, have to be protected against biological degradation by fungi and other microorganisms. Due to European legislation (Biocidal Products Regulation 528/2012), the selection of possible chemical agents, which are still allowed to be used, is diminishing rapidly. The use of previously widely applied, very ...

Durability of acetylated Radiata pine: Laboratory tests and performance in practice
2020 - IRG/WP 20-40899
Wood acetylation is an established process to enhance biological durability and dimensional stability of lower valuable wood species without the use of biocides. Acetylated Radiata pine (ACCOYA® wood) has been on the market for more than 10 years now, starting in 2007. Numerous lab tests have confirmed the high durability of acetylated Radiata pine. Here, additional data with four Radiata pine ...
