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...

Rapid detection of the Alaska yellow cedar, Callitropsis nootkatensis (Cupressaceae) extractives using Fourier transform infrared (FT-IR) spectroscopy
2017 - IRG/WP 17-20612
Global changes in wood harvesting towards plantation species grown on much shorter rotations has the potential to markedly alter wood quality perceptions. Nowhere is this more risky than with naturally durable species where there is compelling evidence that faster grown woods tend to be less durable. The ability to non-destructively assess durability may allow growers to identify materials that re...

Rapid Screening test of potential antimicrobial agents for wood coatings
2018 - RG/WP 18-20644
A two-part screening test has been developed to evaluate additives for wood coatings. First, an additive is tested in the microbial laboratory and evaluated based on its inhibitory properties against selected test organisms, directly on agar plates. A microbial growth analysis is prepared and evaluated. If the additive is considered effective, it will be tested in a standard top coating (acrylic o...

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...

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...
