Interaction between AA9 lytic polysaccharide monooxygenase and PQQ-dependent pyranose dehydrogenase in cellulose degradation
2025 - IRG/WP 25-11075
Wood-decaying fungi degrade cellulose, the primary polysaccharide in wood, as a nutrient source by utilising various hydrolytic and oxidative enzymes. Among these, lytic polysaccharide monooxygenase (LPMO9) has gained attention as a key enzyme that enhances the degradation efficiency of other cellulases. The activity of LPMO9 requires both electrons and hydrogen peroxide. It has been reported that...

Exploration of flavoenzymes from the wood rotting basidiomycete Armillaria cepistipes using protein structure prediction
2025 - IRG/WP 25-11077
Wood rotting basidiomycete is one of the major organisms that cause wood deterioration. Oxidoreductases secreted by those fungi are known to play key roles in the mechanism of wood cell wall degradation. As certain extracellular oxidoreductases including lignolytic peroxidases and lytic-polysaccharide monooxygenases from wood rotting fungi utilise hydrogen peroxide as a substrate in their catalyti...

Effect of the Cellulose-Binding Domain Associated with Xylanase on the Degradation of Softwood and Hardwood Xylan
2025 - IRG/WP 25-11078
Brown rot fungi rapidly degrade hemicellulose, which is recognized as a key decomposition process during the early stages of wood decay. Brown rot fungi possess multiple genes encoding hemicellulose-degrading enzymes, suggesting that enzymatic hydrolysis plays an important role in this process. Hemicellulases produced by these fungi often contain an additional domain classified as carbohydrate-bin...

Sustainable and environmentally friendly bio-based protection against fire
2025 - IRG/WP 25-20756
Flame-retardant agents are used to confer fire resistant properties with effects strongly dependent on their ability to form char during the thermal degradation. The char coats the polymeric materials and provides a good barrier against heat and oxygen diffusion, thus reducing the combustion rate of the polymeric materials. Halogenated agents that are used today are toxic and may cause severe heal...

A Case Study of Vogvarjeva hiša, a Local Ethnographic Museum
2025 - IRG/WP 25-41027
The Vogvarjeva hiša in Spodnje Duplje, Slovenia, is an example of traditional 18th Century wooden architecture and an important element of the region’s cultural heritage. The building was constructed from local timber on stone foundations and reflects the traditional rural building techniques of the Gorenjska region. Since it was declared a cultural monument in 1985, it has functioned as an eth...

Non-destructive methods for field assessment of wood biodeterioration in hardwood trailer decks exposed to tropical environments
2025 - IRG/WP 25-41039
Apitong (Dipterocarpus spp.), an increasingly rare tropical hardwood from the rainforest in Southeast Asia, has long been used as decking materials for open-bed trailers and trucks across North America. As the natural population of Apitong trees steadily declines, there is an urgent need to find sustainable, domestically sourced alternatives for trailer decking. A recent project evaluated the perf...

Investigation of the Correlation between Blue-Light and Transparent Wood and Its Impact on Eye cells
2025 - IRG/WP 25-41042
The widespread use of LED blue light (400–480 nm) in modern life has raised concerns due to its potential risks to eye health, including retinal cell damage and vision degradation. Transparent wood, a renewable material with unique optical properties and environmental benefits, shows promising potential for blue light protection applications. This study investigates the modulation of lignin cont...

Development of an Early Degradation Diagnosis Technology for Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41047
Accurately predicting the degradation state of wood coatings is challenging, and as the coating deteriorates, it becomes a major factor accelerating the degradation of the wood itself. In this study, we aimed to develop a diagnostic technology that combines mid-infrared spectroscopy and machine learning to assess latent coating degradation, which cannot be detected visually, and to enable appropri...
