Physiological characterization of a key enzyme involved in gaseous COS assimilation in the filamentous fungus Trichoderma harzianum
2025 - IRG/WP 25-11072
Filamentous fungi are among the primary organisms responsible for the biological deterioration of wood, including wood decay and surface contamination. Therefore, understanding their physiological mechanisms is important for developing effective wood preservation strategies. Most physiological studies on filamentous fungi have focused on the metabolism of major elements, such as carbon in the form...

Screening of fungi capable of degradation of β-aryl ether bond from lignin model compounds by using highly fluorescent-emitting detection
2025 - IRG/WP 25-11081
Lignin is an aromatic polymer and composed of phenylpropane units polymerized by dehydrogenases in cell walls. Lignin has a complex chemical structure with C-C and C-O-C bonds, and it is difficult to decompose lignin structure by microorganisms in natural conditions. For the microbial degradation of lignin structure, wood decay fungi can non-specifically degrade the lignin polymeric structure by o...

Potential co-valorization of pyrolysis tars from five wood species form Tunisia as wood preservatives bases: Chemical compositions, antifungal and anti-termite activities
2025 - IRG/WP 25-20739
The pyrolysis of five Tunisian wood species (Ceratonia siliqua, Eucalyptus camaldulensis, Eucalyptus maidenii, Pinus pinea, and Quercus canariensis) was carried out in a custom-designed carbonisation reactor developed at the INRGREF's Wood Technology Section (Tunis, Tunisia). This process aimed to produce both char and pyrolysis by-products, particularly pyrolysis oils. The experiments were conduc...

Properties of plasma etched super black wood
2025 - IRG/WP 25-30825
Super-black materials have very low reflectivity due to structural absorption of light. They are attracting considerable scientific and industrial attention because of their important applications in many fields including astronomy, photovoltaics, and optical science, amongst others. We have developed the first super-black material from wood by etching transverse basswood (Tilia americana L.) surf...

Effect of photodegradation on fungal colonization on wood during initial stage of brown-rot decay
2025 - IRG/WP 25-41024
Photodegradation and decay may happen simultaneously on wood under many exposure conditions. The aim of this study was to explore the effect of photodegradation on fungal colonization during initial stage of brown-rot decay of wood. For this purpose, southern pine (Pinus spp.) wood was exposed to accelerated UV weathering for different durations, and then decayed by a brown rot fungus (Gloeophyllu...
