Steam Pre-conditioning Treatment Prior to Acetylation: Impact on Dimensional Stability, Moisture Response Behaviour, and White-Rot Fungal Resistance of Hevea brasiliensis and Mitragyna ciliata Wood
2022 - IRG/WP 22-40930
The effect of steam pre-conditioning treatment on the dimensional stability, moisture response behaviour, and durability against white-rot fungus P. chrysosporium of acetylated Hevea brasiliensis and Mitragyna ciliata wood species were assessed. Defect-free specimens of both species from the top, middle, and base positions were selected, prepared according to ASTM D143-09 & ASTM D-2017 standards a...

Evaluation of Decay Resistance for the Larch Wood Heat-treated with Superheated Steam
2022 - IRG/WP 22-40956
Heat-treatment of wood is a process that involves applying heat ranging 160–260°C to improve its physico-mechanical properties and resistance against wood rot fungi. The level of the changes in the wood properties by heat-treatment differs depending on the temperature and duration of heat-treatment, as well as the types of heat transfer media used for heat-treatment. The heat-treatment on wood ...

Characterization of cell wall morphology and water-soluble extractives in Japanese larch decayed by white-pocket-rot fungi
2024 - IRG/WP 24-11034
Porodaedalea chrysoloma (Fr.) Fiasson & Niemelä is a basidiomycete that can cause white-rot decay in Japanese larch (Larix kaempferi) heartwood. P. chrysoloma is a white-rot fungus with a unique pattern that causes white-pocket-rot in the xylem of Japanese larch. However, the mechanism by which P. chrysoloma yields the pattern of white-pocket-rot in Japanese larch heartwood remains unclear. Thus,...
