“…In recent years, the number of scientific reports on new biocidal preparations for wood protection applications based on substances of natural origin has increased [39,40]. The 30% solution of cinnamon bark oil used at a dose of 200 g/m 2 turned out to be a good fungicide, protecting wood-based boards against the development of mold fungi, but not effective enough to provide long-term protection.…”

Porous wood-based boards, like any lignocellulosic material, are susceptible to biocorrosion caused by mold fungi. Their durability can be extended by using biocides. Due to the fact that porous boards are considered an ecological material, it would be beneficial to also use natural agents to protect them. For this purpose, the surface of softboards was protected with a 30% solution of cinnamon bark oil in ethanol. Three application levels were used: 75 g/m2, 120 g/m2, and 200 g/m2 of solution. It has been shown that the cinnamon bark oil solution used at an application rate of 200 g/m2 is an effective fungicide, protecting softboards (SBs) against the development of mold fungi: T. viride and C. globosum. The dominant volatile component of cinnamon oil identified in the boards turned out to be cinnamaldehyde. Three months after treatment, this substance constituted 74% of the volatile components. The proposed treatment method allows for short-term preventive protection of boards against mold fungi.

“…Acetone extract with strongest antifungal activity had the signi cant effect on the color of thermally modi ed poplar wood in our previous study, and it was selected as the extraction solvent (Bi et al, 2022 and2021b). Some studies also indicated that wood extracts extracted with solvents with electrical constants between 4 and 6 have strong antifungal activity and relatively rich chromogenic and auxochrome (Mahlo et al 2010;Candelier et al 2020).…”

“…Some study indicated that extracts from thermally modi ed wood (TMW) have a positive effect on its decay resistance and color (Esteves et al 2008;Sandoval-Torres et al 2010). The extract of TMW provide the possibility to regulate the properties of TMW and improve wood decay resistance and enhance wood color, and will eco-friendly and not reduce its mechanical strength (Bi et al 2022).…”

“…The new extracts with antifungal activity produced by thermally modi cation played an important role in improving the decay resistance (Kamdem et al 2020;Chu et al 2019). Isovanillic acid, vanillin, and other compounds in these extracts will inhibit the growth of wood decay fungi (Candelier et al 2020;Bi et al 2022). Vanillin having been proved to inhibit enzyme activity, damage cell membrane, ATP, and other physiological and biochemical indicators of wood decay fungi (Bi et al 2021a).…”

Thermal modi cation can enhance the color as well as improve the dimensional stability and decay resistance of wood without the use of chemical modi er, but the impact of extracts from thermally modi ed wood (TMW) on performance remains unclear. In order to utilize extracts to regulate the properties of the TMW or prepare the imitate TWM without mechanical loss, the effects of TMW acetone extracts on the color, dimensional stability, and decay resistance of TMW were investigated. The 180°C, 200°C and 220°C thermally modi ed spruce (Picea asperata Mast.) and poplar (Populus tomentosa Carr.)with or without acetone extract were used for CIELab system, anti-swelling e ciency(ASE), and decay resistance test. Fourier infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were used to characterize extracted and unextracted TMW. The results indicated that the extract showed positive effects on the color, dimensional stability (220°C), and decay resistance of TMW, and this effect weakened with the increase of temperature. The brightness difference (∆L*) and the total color difference (∆E*) of the TMW were reduced due to the removal of the extract, and the wood thermally modi ed at 180°C was the most signi cant. The removal of the extract will lead to the improvement of the dimensional stability of the TMW at 180°C and 200°C and the reduction of the TMW at 220°C. The decay resistance of wood thermally modi ed at 180°C, 200°C, and 220°C decreased after extraction, and was most signi cant at 180°C. The antifungal activity of the extract was related to the production of vanillin, isovanillic acid, syringic acid and syringaldehyde. Extract from TMW played an important role in the properties of TMW, and can be used to adjust its properties or as a natural wood modi er.

“…The protection of wood with products of plant or animal origin is often associated with important disadvantages, namely, the susceptibility of these components to leaching from the structure of impregnated wood. Therefore, numerous methods have been used to improve their leaching resistance including the addition of hydrophobic or crosslinking agents, thermal modification, micro-capsulation, or the enzyme-catalyzed method [ 25 , 197 , 198 ]. This section presents examples of formulations whose ingredients can be classified as ecological agents with low impact on human health and the natural environment.…”

The biodegradation of wood and wood products caused by fungi is recognized as one of the most significant problems worldwide. To extend the service life of wood products, wood is treated with preservatives, often with inorganic compounds or synthetic pesticides that have a negative impact on the environment. Therefore, the development of new, environmentally friendly wood preservatives is being carried out in research centers around the world. The search for natural, plant, or animal derivatives as well as obtaining synthetic compounds that will be safe for humans and do not pollute the environment, while at the same time present biological activity is crucial in terms of environmental protection. The review paper presents information in the literature on the substances and chemical compounds of natural origin (plant and animal derivatives) and synthetic compounds with a low environmental impact, showing antifungal properties, used in research on the ecological protection of wood. The review includes literature reports on the potential application of various antifungal agents including plant extracts, alkaloids, essential oils and their components, propolis extract, chitosan, ionic liquids, silicon compounds, and nanoparticles as well as their combinations.
