“…These sugars are mostly responsible for growth of fungi and other deteriorated agents that could not be extracted completely by Chl and Chl + Water, while ethanol and diethyl ether were able to extract sugar compounds of wood surface and inner sections of wood. Also, as shown in Table 3 the most identified compounds are hydrocarbon and phenolic compounds, sesquiterpenes and fatty acids which were reported to have good biological activity (Salem et al 2014(Salem et al , 2016. Beech and spruce woods showed resistance against T. versicolor and Serpula lacrymans with increasing the tannins in their woods (Jeloková and Šindler 1997), but the presence of sugar contents had a negative effect on the wood durability of beech wood (Jeloková and Šindler 2001).…”

Extracted wood samples of Fagus orientalis with different solvents were analyzed for their antifungal activity against white-rot fungus (Trametes versicolor) in an agar plate. The most active extract was analyzed for its antioxidant activity by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method, and the chemical composition were analyzed using gas chromatographymass spectrometry. After the solvent removal of extractives, especially using chloroform (Chl) and Chl-water mixture, losses in the resistance of beech wood had occurred. However, Chl extract was found to be the most active antifungal agent, and the weight loss (30.38%) of specimens after 14 weeks of incubation was higher than that of other extracted specimens. At the concentration of 0.016 mg/mL, the highest activity observed was by Chl extract (89.45%), which was lower than the value of vitamin C (96.63%) at the same concentration. The lowest weight loss values obtained from the decay test were 0.35% and 0.64% for ethanol and ethanol-water extracted beech wood samples, respectively. The highest weight loss values were 30.38% and 23.98% for Chl and Chlwater extracted samples, respectively.

Picea abies and Larix decidua were subjected to GC/MS analyses, and antimicrobial (fungi and bacteria) assays of their stem wood and bark extracts were investigated. L. decidua bark extract exhibited the highest antifungal and antibacterial activities against the microorganisms that were screened. The microbes Penecillium ochrochloron and Aspergillus ochraceus were the most sensitive to the extracts, whereas Candida albicans was the most resistant fungus. L. decidua wood and bark did not exhibit much variation in their antibacterial activities, except against Micrococcus flavus and Pseudomonas aeruginosa. The bacterium most sensitive to the extracts was Escherichia coli, whereas the most resistant was M. flavus. 13-epimanool and α-cedrol were the main components of P. abies wood extract. The main components in its bark were abietic acid, astringin, dehydroabietic acid, and α-terpineol. The main chemical compounds in L. decidua wood extract were abietic acid, oleanolic acid, duvatrienediol, and larixol. The main chemical compounds in its bark were (-)-2,9-dihydroxyverrucosane and larixol. The study revealed that P. abies and L. decidua stem wood and bark extracts contain several compounds that have antimicrobial activities towards diverse human pathogenic, food, and agricultural microbes. These results might guide in future searches for novel natural products with chemotherapeutic uses.

Tree bark, for example, provides not only a physical protective barrier for plants, but also an important chemical defense mediated through the secondary compounds they produce (Horsfall 1980;Merrill 1992;Alfredsen et al. 2008). Numerous studies recently conducted on bark extracts focus on tropical tree spec...

“…The most critical economic concern in the construction industry lies in the selection of less environmentallyaggressive methods in association with the prevention of wood deterioration caused by xylophagous agents (Salem et al, 2016). Among the existing agents, fungi, mainly those belonging to the wood decaying group, cause more damage due to their highly aggressive attack (Fabbri et al, 1997;Mesquita et al, 2009).…”

Resistance of TiO2-treated Eucalyptus botryoides Wood to the Fungus Ganoderma applanatum

The aim of the present study is to investigate the resistance of Eucalyptus botryoides treated with TiO 2 particles to attack by the fungus Ganoderma applanatum. The Bethel treatment method was applied to wood specimens (25 × 25 × 9 mm) and compared to CCB. The wood was subjected to the accelerated decay test and characterized through Rockwell Hardness and Fourier Transform Infrared Spectroscopy (FT-IR). The TiO 2 -treated wood showed lower degradation and greater resistance to the penetration of a steel sphere (Rockwell Hardness) than the untreated wood. In addition, the results of the TiO 2 treatment were statistically equal to those of CCB. The FT-IR analysis showed that the fungus degraded lignin and hemicellulose in untreated samples. The present results showed the TiO 2 efficiency in forming a protective layer on the cell wall and in preventing the development of microorganisms, a fact that verifies its fungicidal action on wood.
