Microscopy evaluation of microbial decay patterns in wood stakes after 6 years in soil contact
2010 - IRG/WP 10-10715
Most studies on wood modification have so far been concerned with service life predictions rather than investigating the decay protection mechanism. Very little is known about the mode of action of these new treatments and about the strategies used by wood degraders in order to utilize the wood material despite a treatment. Access to such knowledge would allow further modification and improvement ...

Towards Understanding the Biology of Wood Decay
2010 - IRG/WP 10-10739
Our previous research has focused primarily on ways to identify the wood decay fungi and microbial community. We continue to explore this complex and dynamic community and its interactions through microbial community ecology studies, gene expression interactions and proteomics. However, in order to better understand the mechanisms of fungal decay, we have sequenced the genome of a copper tolerant...

Growth conditions for fungal decay in wooden constructions – practical experience versus literature
2011 - IRG/WP 11-10758
Data regarding moisture and temperature requirements of decay fungi found in literature have been compared to experience from observations in a large number of Norwegian buildings. A number of selected situations are discussed, among those exposure to high relative humidity, exposure to free water and decay in the supposedly adverse conditions on Svalbard. The moisture content in wood has to be at...

Microbial Community Analysis of Naturally Durable Wood in an Above Ground Field Test
2014 - IRG/WP 14-10826
This paper presents preliminary results of an above ground field test wherein eight naturally durable wood species were exposed concurrently at two sites in North America. Surface samples were taken at regular intervals from non-durable controls and compared to their more durable counterparts. Terminal Restriction Fragment Length Polymorphism was performed to characterize the microbial (bacteria, ...

Monitoring Diversity and Colonization Patterns of Wood-Inhabiting Fungi Using Field Stake Tests
2017 - IRG/WP 17-20614
Advances in molecular identification of microbial communities enabling rapid microorganism determination have allowed ecological data to be increasingly incorporated into standardized wood performance tests. Combining standard field tests with molecular methods to study wood-associated microflora can help to better understand fungal colonization and decay processes of wood in service. The potentia...

Effect of MVOC exposure on mycelial growth of wood rotting fungi
2021 - IRG/WP 21-10977
It is well known that wood rotting fungi produce microbial volatile organic compounds (MVOCs) as metabolites. In our previous studies, we have found that some MVOCs produced by wood rotting fungi are common to fungal species tested in the studies, while others are specific to each species. Furthermore, it has been also shown that each wood rotting fungi do not always produce the same type of MVOCs...

Effect of volatile organic compounds produced by wood rotting fungi on mycelial growth
2023 - IRG/WP 23-11023
Microorganisms such as fungi or bacteria produce volatile organic compounds (so-called MVOCs: Microbial Volatile Organic Compounds) as metabolites. Some MVOCs have been found to be biologically active, for example inhibition of spore germination, and when fungi of different species encounter each other, the MVOCs pattern change, suggesting that MVOCs play a role as a mediator for biological intera...

A mini review on climate change impact on bio-ecology of subterranean termites
2023 - IRG/WP 23-50375
Climate change is creating possibilities of changes in the bio-ecology of termites across the globe. This change will be felt differently in different regions. While changes in swarming times will be common in the Northern hemisphere, the tropic will encounter more life-history related changes. But termites posing newer threats induced by climate change will be mostly dependent on human activitie...
