“…Obtaining films with controlled physico-chemical characteristics broadens their field of application. TiO 2 films may have different morphologies and wettability depending on the precursor pH (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14). This characteristic may be a great advantage in using the nanoparticles coatings in various humidity environments [16].…”

“…An inefficient polymer coating can lead to loss in mechanical properties and integrity of the matrix and wood discoloration due to lignin degradation. New composite materials were developed, as aromatic impregnating agents (insecticides or fungicides) such as creosote, halogenated carbamates, benzothiazoles, pentachlorophenol, (alkyl) imidazoles, bis (tributyltin) oxide, or salt-based impregnates such as borates, quinolinolates, naphthenates of copper, zinc or chromated copper arsenate-based preservatives (CCA) in several commercial variants and so forth [8][9][10], fluoroalkyl functional oligomeric silane system [11], short-chain amino silicones [12], alkoxysilanes with different organic groups [R'Si(OR″)] [13], zinc oxide (ZnO) nanoparticles dispersed in maleic anhydride-modified polypropylene (MAPP) [14], and titanium dioxide (TiO 2 ) nanoparticles [15][16][17][18][19].…”

The complex methods of diagnosis investigation of the wood artifacts state and proper materials for their protection against decay are very important goals in cultural heritage. This chapter focuses on the recent trends in micro-and nanostructured polymer systems for application in cultural heritage and on wood preservation, especially. The synthesis, properties, and applications, as well as the relevant analysis techniques to reveal the structures and properties of polymer systems, are discussed, too. To overcome the specific problems that exist for wood artifacts, some aspects should be treated: effects of the environmental factors, as moisture and pollutant absorption into the wood fibers, over-exposure effect of sun or artificial light sources, biological attack of different microorganisms, and the effects of the protective and decorative coatings.

“…Copper (Cu) is the primary biocide component presently used to protect wood against soft-rot fungi in ground contact [1], but fails to protect against a range wood destroying basidiomycetes [2, 3]. Diverse mechanisms involved in the Cu-tolerance process of basidiomycetes have been described such as the ability to absorb Cu into cell wall components, extracellular chelation by metabolites and intracellular complexion with metallothioneins [4–9]. The absence of a co-biocide, in combination with an exchange of wood poles on identical sites with high fungal inoculum, has resulted in an increase in the number of premature failures of wood utility poles in the last decades [3, 10].…”

The production of new generation of wood preservatives (without addition of a co-biocide) in combination with an exchange of wood poles on identical sites with high fungal inoculum, has resulted in an increase of premature failures of wood utility poles in the last decades. Wood destroying basidiomycetes inhabiting sites where poles have been installed, have developed resistance against wood preservatives. The objective of the in vitro studies was to identify a Trichoderma spp. with a highly antagonistic potential against wood destroying basidiomycetes that is capable of colonizing Cu-rich environments. For this purpose, the activity of five Trichoderma spp. on Cu-rich medium was evaluated according to its growth and sporulation rates. The influence of the selected Trichoderma spp. on wood colonization and degradation by five wood destroying basidiomycetes was quantitatively analyzed by means of dry weight loss of wood specimens. Furthermore, the preventative effect of the selected Trichoderma spp. in combination with four Cu-based preservatives was also examined by mass loss and histological changes in the wood specimens. Trichoderma harzianum (T-720) was considered the biocontrol agent with higher antagonistic potential to colonize Cu-rich environments (up to 0.1% CuSO4 amended medium). T. harzianum demonstrated significant preventative effect on wood specimens against four wood destroying basidiomycetes. The combined effect of T. harzianum and Cu-based wood preservatives demonstrated that after 9 months incubation with two wood destroying basidiomycetes, wood specimens treated with 3.8 kg m-3 copper-chromium had weight losses between 55–65%, whereas containers previously treated with T. harzianum had significantly lower weight losses (0–25%). Histological studies on one of the wood destroying basidiomycetes revealed typical decomposition of wood cells by brown-rot fungi in Cu-impregnated samples, that were notably absent in wood specimens previously exposed to T. harzianum. It is concluded that carefully selected Trichoderma isolates can be used for integrated wood protection against a range of wood destroying basidiomycetes and may have potential for integrated wood protection in the field.

“…L. sulphureus is considered a cosmopolitan species causing brown cubical heart rot in many deciduous and coniferous trees (11). It is known to produce metabolites with antioxidant and antimicrobial properties (12,13) and natural dyes (14,15), in addition to the potential for bioremediation of treated wood (16) and decolorization of textile e uents (11). During wood decay, L. sulphureus causes higher polysaccharide weight loss than lignin loss (17).…”

Background: Wood-decay basidiomycetes are effective for the degradation of highly lignified and recalcitrant substrates. Brown-rot strains produce carbohydrate-active enzymes involved in the degradation of lignocellulosic materials, along with a non-enzymatic mechanism via Fenton reaction. Differences in the lignocellulose metabolism among closely related brown rots are not completely understood. Here, a multi-omics approach provided a global understanding of the strategies employed by L. sulphureus ATCC 52600 in the degradation of lignocellulosic by-products derived from sugarcane and Eucalyptus. Results: To evidence the oxidative-hydrolytic mechanism, the Laetiporus sulphureus ATCC 52600 genome was sequenced and the response to lignocellulosic substrates was analyzed by transcriptomics and proteomics. The transcriptomic profile in response to a short cultivation period on in natura sugarcane bagasse revealed 128 out of 12,802 upregulated transcripts. The high upregulated transcripts included a set of redox enzymes along with hemicellulases. The exoproteome produced in response to extended time cultivation on Avicel, and steam-exploded sugarcane bagasse, sugarcane straw, and Eucalyptus (from Eucalyptus grandis) revealed 121 proteins. Contrasting with the mainly oxidative profile observed in the transcriptome, the secretomes showed a diverse hydrolytic repertoire including constitutive cellulases and hemicellulases, in addition to 19 upregulated proteins relative to glucose. The secretome produced on sugarcane bagasse was evaluated in the saccharification of pretreated sugarcane straw by supplementing a commercial cocktail. Additionally, growth analysis revealed that L. sulphureus ATCC 52600 has higher efficiency to assimilate glucose than other mono- and disaccharides.Conclusion: This study shows the singularity of L. sulphureus ATCC 52600 compared to other Polyporales brown rots, regarding the presence of cellobiohydrolase and peroxidase class II. The multi-omics analysis reinforces the oxidative-hydrolytic metabolism involved in lignocellulose deconstruction, providing insights into the overall mechanisms as well as specific proteins of each step.
