The importance of proper taxonomic identification, a case study with Reticulitermes spp. from USA
2012 - IRG/WP 12-10774
Taxonomy has been evolving with recent advancement in molecular and internet technologies. The importance of a stable taxonomic foundation is unquestionable as this science provides crucial information about evolutionary relationships and allows questions about the life history and ecology of organisms to be asked. We hope to highlight the issues and lessons we have learned from revising the taxon...

Detection of Aureobasidium as the dominant fungus on coated wood
2013 - IRG/WP 13-10796
Wood is often covered with a coating in order to protect the surface. Unwanted dark mold growth on paint covered surfaces in external conditions is a familiar phenomenon. Simple microbial techniques have commonly been used to determine the dominant fungal species present in the discoloured area, for example morphological analysis of microscopic preparations of fungal pieces sticking to an adhesive...

Communities of mold fungi on flooded building materials
2013 - IRG/WP 13-10799
A small building built to residential code was flooded using farmland pond water to a depth of two feet at Tuskegee University. The building was drained and left enclosed for an additional three weeks. A total of 168 material samples were removed either immediately after opening (wet) or seven months after flooding (dry). Wall materials sampled included fiberglass batt insulation, gypsum wallboard...

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...

Identification of soft-rot fungi existed in the samples from the galley excavated at Yenikapi
2014 - IRG/WP 14-10833
The shipwrecks of the Middle Byzantine period were excavated during the construction of the Marmaray railway and metro station in Yenikapı between 2004 and 2012. This has become the largest investigations because of the size and the number of the shipwrecks and its associated artifacts. In the previous report, the electron micrographs of the samples revealed that a wide range in the degree of...

Identification of the key factors influencing development of the blue stain fungi
2016 - IRG/WP 16-10872
Service life of wood is more and more frequently affected by aesthetic requirements than functional ones. In order to elucidate various aspects of service life, model house with façade elements made of 22 materials was built on the field test site at Department of Wood Science and Technology in Ljubljana. Colour and fungal disfigurement is among other parameters monitored on this house. In parall...

A review on prediction methods of wood natural durability
2017 - IRG/WP 17-10892
Natural durability of timber may be defined as “inherent ability of timber to attack by wood destroying organisms (bacteria, fungi, insects, marine borers) without preservative treatment. On the base of biological tests, EN-350-2 standard (Afnor, 1994), describe the classification of wood species according to their natural durability. But these specifications are not adapted in the case of wood ...

Molecular identification of marine borers causing wood deterioration on marine facilities in Korea
2019 - IRG/WP 19-10955
The deterioration factors of wood which was used in the marine environment, Tongyeong (South Coast) and Incheon (West Coast) in Korea, were investigated in order to develop technologies for safe and long-term use of timber in ocean facilities.
The marine microorganisms isolated by damaged wood were identified as morphological Chelura sp. and Teredo sp. As a result of DNA sequencing, it was confir...

Comparative performance of wood/wood-based claddings predicted by four hygrothermal simulation tools
2019 - IRG/WP 19-20646
A number of hygrothermal numerical simulation packages are available, either wholly or partially dedicated to heat, air and moisture transfer simulations of building materials and wall assemblies. The objective of this work was to compare the hygrothermal responses and the moisture performance of western red cedar and composite wood claddings of a wood frame wall as predicted by four hygrothermal ...

Identification of Antifungal Compounds in Konjac Flying Powder and Assessment against Wood Decay Fungi
2019 - IRG/WP 19-30737
The antifungal activity of konjac (Amorphophallus rivieri) flying powder (a by-product produced during mechanical processing of konjac flour) ethanol extract was evaluated against wood decay fungi in culture. Compounds associated with antifungal activity in the extracts were isolated and purified by silica gel column chromatography. The antifungal active fractions were identified by ultra-high-per...

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...

Fungal degradation of oak timber bridges
2025 - IRG/WP 25-11058
Wood is increasingly recognised as an eco-friendly building material, but its organic nature makes it vulnerable to degradation, especially in outdoor applications exposed to moisture. This study investigates wood-decaying fungi affecting oak timber bridges in Hanover, Germany. The study aimed to identify the fungal species using culture-independent methods and to examine the impact of poorly exec...

Durability and molecular analysis of fungal communities in wood exposed above ground
2025 - IRG/WP 25-11068
The objective of the study was to explore the durability of wood exposed above ground, comprising a wide diversity of wood species and treatments and extensive assessment data on wood durability in ongoing long-term testing. Larch species and Scots pine heartwood, two tropical species ntholo and ncurri and a number of treated wood by copper-based formulations and alternatives (silanes, spiroborate...

AI Models for Accelerating Wood Protection Testing: Development of Predictive Tools Based on Long-Term Field Test Data
2025 - IRG/WP 25-41023
In this study, we present the development of DecAI, an artificial intelligence (AI) model designed to optimise and accelerate performance evaluations of wood protection products in the European EN 330:2014 "Field test: L-joint method."
