Extraction, identification and antifungal activity of polar extractives originated from various wood species
2020 - IRG/WP 20-20673
Extractives are non-cell wall small molecules present in wood and other lignocellulosic materials that can be removed by solvents. Although they represent a minor fraction in comparison with the structural cell wall components, they are an important source of functional groups or molecules with bioactivity or antioxidant properties, that could be used in medicine, cosmetic or wood preservation. T...

The influence of chemical compounds on wood cell wall to surface cracks
2020 - IRG/WP 20-40908
Degradation due to cracking and dimensional changes caused by drying, have a significantly negative impact on the preservation and durability of wood. Therefore, the prevention of surface cracking, which tends to occur during the drying process, is vital. High temperature set drying is one of the most effective methods for preventing wood surface cracking. It begins with softening the wood at a hi...

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...

Impregnation of wood with antifungal compounds from low-quality tree biomass
2022 - IRG/WP 22-30763
In this paper we have reviewed recent research on the development of bio-based preservative formulations for wood done at the Department of wood science and technology, Ljubljana. Preservative formulations used in this investigation were prepared using plant polyphenols as biocidal agents. These nonstructural components of wood were stilbenes and flavonoids, and were extracted from wood of broken ...

Effect of enzymatic inhibitors on the population of Reticulitermes grassei and their associated microbiota
2023 - IRG/WP 23-11008
Termites are pests that invade urban, agricultural and forest environments worldwide. They are economically important owing to the damage they cause to wood, wood products, building materials, agricultural products and forests. There are many methods for its control, but many of them cause negative environmental effects due to their toxicity. In termites, dietary change or antibiotic treatment may...

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...
