The potential of Wacapou (Vouacapoua americana) extracts to develop new biobased protective solutions for white woods
2024 - IRG/WP 24-20724
The valorisation of Amazonian wood residues into active chemical compounds could be an eco-friendly, cost effective and valuable way to develop wood preservatives formulations in order to enhance the decay and termite resistances of low durable wood species, by impregnation processes. Wacapou (Vouacapoua spp., Fabaceae) is a well-known Guianese wood species for its use in local wood construction ...

Synthetic Oxalate/ß-glucan Fungal Extracellular Matrix Demonstrates Potential Inhibition of Extracellular Enzyme Diffusion into Wood Cell Walls, and Calls into Question the Role of Enzymes in Wood Decay
2025 - IRG/WP 25-11053
ß-glucan is the major component of the extracellular matrix (ECM) of many fungi, including wood degrading fungi. Many of these species also secrete oxalate into the ECM. Our research demonstrates that ß-glucan forms a novel, previously unreported, hydrogel at room temperature with oxalate. This finding better explains the gel-like nature of the fungal ECM. Oxalate, at relatively low levels, was ...

Interaction of cellulolytic enzymes with fungal cell wall polysaccharides
2025 - IRG/WP 25-11071
Wood rotting fungi are the primary agents responsible for the decomposition of wood in natural environments. These fungi secrete a variety of enzymes to degrade the chemically and structurally resistant components of the wood cell wall. Some of these enzymes possess a carbohydrate-binding module (CBM), which enhances enzymatic efficiency by increasing their affinity to the substrate. Previously, w...

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...

Enhanced Flame Retardancy in Wood via In Situ Polymerization of Phosphorus-Containing Ionic Liquids
2025 - IRG/WP 25-20736
Wood, a ubiquitous material in furniture and construction, is limited by its natural flammability. Existing wood flame retardant technologies are often ineffective and lack environmental sustainability. Ionic liquids (ILs), known for their non-flammability and non-volatility, offer a green solvent solution to these challenges. In this study, we synthesized a novel phosphorus-containing, polymerisa...

Functionalization of wood with nano-sized titanium dioxide – Efficacy against mould growth and effect on cell wall integrity
2025 - IRG/WP 25-20740
Nano-sized titanium dioxide (nano TiO2) is a photocatalytic compound that generates reactive radicals under UV radiation, which can inhibit microbial growth and impart self-cleaning properties. This effect has been widely utilised on materials such as glass or tiles. This study investigates the potential of nano TiO2 treatments to prevent mould growth on wood and their impact on cell wall integrit...

Evaluation of oak bark extracts as bio-based preservative agents in wood protection
2025 - IRG/WP 25-30833
Bark represents a major by-product of the forestry sector and is often referred to low value uses such as combustion for energy, soil mulching or animal bedding. Nevertheless, bark contains a wide array of bioactive constituents, offering considerable potential for transformation into value-added wood protection agents. Developing sustainable wood treatments based on these natural compounds aligns...

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...

Investigation of Impregnation Factors for Biomass-Based Phenol-Formaldehyde Resins
2025 - IRG/WP 25-41044
This study investigates the impregnation factors affecting the treatment of wood with biomass-based phenol-formaldehyde (PF) resins, such as impregnation methods, resin properties, and setting parameters like time and pressure. The goal is to ensure effective resin penetration into the wood cell wall structure, thereby enhancing wood durability and mechanical properties. Previous literature has la...

Valorisation of bark extractives for wood and plant protection: the Extrabark project
2025 - IRG/WP 25-50415
The Extrabark project is an Interreg collaborative project between Lorraine in France, Wallonia in Belgium, the Saarland in Germany and Luxembourg. The objectives of the project are to develop a complete value chain of valorisation of bark generated by wood industry via the utilization of extracts or molecules for the protection of plants and wood material as a bio-sourced alternative to petrochem...
