“…The environmental protection agency (EPA) in USA banned the use of wood treated with copper-chrome-arsenic (CCA) for residential purposes after 2003. Alternative products such as wood-plastic composites (WPC), chemically modified wood, and thermally modified wood have grown rapidly (Baysal and Yalinkilic 2005, Chang and Chang 2006, Kartal et al 2006, Boonstra et al 2007, Clausen and Yang 2007, Lekounougou et al 2008. Thermal modification is an eco-friendly technology which improves the wood durability.…”

This study was aimed at evaluating the effect of thermal modification temperature on the mechanical properties, dimensional stability, and biological durability of Picea mariana. The boards were thermally modified at different temperatures 190, 200 and 210°C. The results indicated that the thermal modification of wood caused a significant decrease in the modulus of rupture (MOR) after 190°C, while the modulus of elasticity (MOE) seemed less affected with a slight increase up to 200°C and slight decrease with further increase in temperature. The hardness of the thermally modified wood increased in the axial direction. This increase was also observed in tangential and axial directions but at a lesser extent. The final value was slightly higher in axial direction and lower in radial and tangential directions compared to those of the untreated wood. Dimensional stability improved with thermal modification in the three directions compared to the dimensional stability of unmodified wood. The fungal degradation results showed that the decay resistance of thermally modified wood against the wood-rotting fungi Trametes versicolor and Gloephyllum trabeum improved compared to that of the untreated wood. By contrast, the thermal modification of P. mariana had a limited effect on the degradation caused by the fungus Poria placenta.

“…Caffeine and its derivatives are some of the most common constituents in coffee extracts, and it is also present in spent coffee extracts (Torres-Valenzuela et al 2019) and in silverskin (Bresciani et al 2014). Caffeine has already been studied as an antifungal agent against wood-decaying fungi in vitro (Lekounougou et al 2007), and it has also been tested as a wood preservative against moulds and decay fungi (Kwaśniewska-Sip et al 2018, Broda et al 2018. Additionally, caffeine has been tested as an ingredient in possible bio-friendly wood preservative formulations (Mazela et al 2016).…”

“…Alternative products like wood-plastic composites (WPC), chemically modified wood, thermally treated wood, and low-or non-toxic wood preservatives are rapidly developing (Pritchard 2004;Baysal and Yalinkilic 2005;ZabielskaMatejuk 2005;Kartal et al 2006;Chang and Chang 2006;Clausen and Yang. 2007;Boonstra et al 2007;Lekounougou et al 2008). Researches and explorations of environmentally benign fungicides for lignocellulosic materials are essential for the further evolution.…”

Wood-rotting fungi lead to great economic losses of lignocellulosic materials. The influence of extractives on the decay resistance of Michelia formosana wood and the antifungal activities of heartwood extract and its constituent against wood-rotting fungi were evaluated. Results revealed that extractives had a strong influence on the decay resistance of M. formosana heartwood. The unextracted heartwood block was resistant to fungi, while the extracted heartwood block was not. Antifungal activities of ethanolic extract from heartwood were assessed; results revealed that the ethanolic extract possessed good antifungal activity against wood-rotting fungi. The ethanolic extract was further separated into four fractions including n-hexane-soluble fraction, ethyl acetate-soluble fraction, n-butanol-soluble fraction, and water-soluble fraction. Among these fractions, the n-hexane-soluble fraction exhibited the best antifungal ability. An alkaloid, liriodenine, was isolated from the active n-hexane-soluble fraction. IC 50 values of liriodenine against the white-rot fungi Lenzites betulina and Trametes versicolor were 0.76 and 3.50 lg/mL, respectively. IC 50 values of liriodenine against the brown-rot fungi Laetiporus sulphureus, Gloeophyllum trabeum, and Fomitopsis pinicola were all lower than 2.0 lg/mL. Results indicated that liriodenine exhibited a broad spectrum of antifungal activity and great potential to develop as an environmentally benign fungicide for the preservation of lignocellulosic materials.
