Investigating wood anatomical factors influencing the treatability of refractory southern pine- an imaging approach
2023 - IRG/WP 23-40975
Southern pine sapwood is non-durable, and preservative treatment is necessary to protect it against biological degradation. According to AS 1604.1 2021, timber products must have their sapwood fully treated with preservatives for various applications and hazard classes. However, there is a growing industry concern over the refractory sections of sapwood, which are untreated pockets of wood that do...

Time-lapse evaluation of Aureobasidium pullulans growth on selected lignin derivatives and chitosan
2024 - IRG/WP 24-11032
Wood, often referred to as the “building material of the 21st century”, has gained recognition as an attractive alternative to several traditional building solutions. To enlarge the application of wood, several properties including biotic and abiotic degradation resistance need to be improved. Consequently, new solutions are available on the market that ensure expected properties and functiona...

Do naturally sequestered biocidal metals contribute to the marine borer resistance of turpentine?
2024 - IRG/WP 24-11036
Turpentine wood is renowned for its resistance to attack by molluscan marine borers. This resistance is thought to be due to its high silica content, and possibly the presence of other, as yet unknown, compounds. Silica in turpentine wood is present as particles in rays, but in many plant species silica also occurs in cell walls. We hypothesized that Si is present in cell walls of turpentine, but ...

X-ray fluorescence microscopy of copper ion distribution in decay of copper-treated wood by Fibroporia radiculosa
2024 - IRG/WP 24-11047
Copper is an essential metal ion for eukaryotic life and must strictly be regulated as excess levels can cause oxidative damage, enzyme inhibition and denaturation, interruptions in nutrient transport and even cellular death. Copper-based wood treatments have efficacy against a wide range of biological organisms including decay fungi and are used in the majority of preservative formulations for ou...

Investigation of oxalic acid production in brown-rot fungi
2025 - IRG/WP 25-11074
Brown-rot fungi play a crucial role as wood decomposers in forests and are also known as the main cause of biodeterioration of wooden buildings in Japan. Therefore, understanding their decomposition mechanisms is important for the maintenance and preservation of wooden structures. While white-rot fungi generally use enzyme-system for degradation, many brown-rot fungi lack cellobiohydrolases which ...

Transmission poles - Analysis of causes of premature failure in Slovenia
2025 - IRG/WP 25-20745
The study focuses on analysing the causes of the premature collapse of wooden transmission poles in Slovenia, where there have been several cases of rapid fungal decomposition of poles despite the planned lifespan of 30 to 50 years. The poles were made of Scots pine wood and impregnated with a copper-ethanolamine wood preservative. The research aimed to assess the condition of standing poles and e...
