Role of microbiota in wood degradation by Reticulitermes grassei and Bursaphelenchus xylophilus
2022 - IRG/WP 22-20684
Xylophagous organisms can cause damage both in forests and in felled wood. Bursaphelenchus xylophilus, which causes "Sudden Pine Wilting" in coniferous forest masses, and is currently considered a quarantine organism in the European Union. On the other hand, structural and carpentry wood is affected by subterranean termites (Reticulitermes spp.), that cause serious damage, both in buildings and fu...

Molecular dynamics investigation of wood modification with furfuryl alcohol
2022 - IRG/WP 22-40931
Molecular dynamics (MD) was applied to investigate and understand the structural characteristics and the interaction of cellulose and lignin with furfuryl alcohol for explaining the wood modification process. A single chain of cellulose polymer model and a softwood lignin model was considered to represent cellulose and lignin polymers. The obtained radial distribution function results revealed tha...

Isolation of the microbiota from wood decay insects and some of their enzymatic activities
2023 - IRG/WP 23-11014
Wood decay organisms have the ability to degrade wood components (cellulose, hemicellulose and lignin) by enzymatic capacities, but these enzymes can belong to the proper organism, or to the associated microbiota. The identification of the microorganisms, as well as their role in the digestion of many substrates not always is very well known.
The wood decay insects produce big damages in wood str...

Resistance of phenol formaldehyde impregnated beech (Fagus sylvativa L.) LVL against biodegradation in soil contact
2023 - IRG/WP 23-40965
Alternatives to preservative impregnation are emphasized in Germany and other European countries. Even though these treatments significantly improve wood's resistance to decay, they often do not have a beneficial impact on the dimensional stability. One alternative product, which may be used in ground contact for items like poles and railway sleepers, could be beech (Fagus sylvatica L.) laminated ...
