Improved Durability of Wood Treated with Nano Metal Fluorides against Brown-Rot and White-Rot Fungi
نویسندگان
چکیده
Low-water soluble metal fluorides such as magnesium fluoride (MgF2) and calcium (CaF2) were evaluated for decay protection of wood. Initially, the biocidal efficacy nano (NMFs) against wood destroying fungi was assessed with an in-vitro agar test. The results from test showed that medium containing MgF2 CaF2 more efficient in preventing fungal than stand-alone or CaF2. These fluorides, their nanoscopic form synthesized using fluorolytic sol-gel synthesis, introduced into sapwood Scots pine beech then subjected to accelerated ageing by leaching (EN 84). MAS 19F NMR X-ray micro CT images present treated wood, unleached leached. Decay resistance NMFs tested Rhodonia placenta Trametes versicolor accordance EN 113. Results revealed mass losses reduced below 3% combination It is concluded provide full even after it has been leached can be used preservatives outdoor environments.

Oxidative Degradation of Wood by Brown-Rot Fungi
Brown-rot fungi are Basidiomycetes that remove cellulose and other polysaccharides from wood, leaving an amorphous, brown, crumbly residue that is composed largely of lignin, hence the name brown-rot. Decay by brown-rot fungi is by far the most serious type of damage to wood in-service. These fungi cause structural failure before losses in total wood substance are detected. The effect of brown-...
متن کاملPectin degradation during colonization of wood by brown-rot fungi
Brown-rot decay results in rapid reduction in degree of polymerization of holocellulose, with concomitant strength loss without removing lignin. Development of new methods of wood protection will require focusing on early events in the sequence of fungal attack during colonization. Pit membranes (sapwood) of wood cell walls represent a readily available source of nonlignified carbohydrate, i.e....
متن کاملExtensive sampling of basidiomycete genomes demonstrates inadequacy of the white-rot/brown-rot paradigm for wood decay fungi.
Basidiomycota (basidiomycetes) make up 32% of the described fungi and include most wood-decaying species, as well as pathogens and mutualistic symbionts. Wood-decaying basidiomycetes have typically been classified as either white rot or brown rot, based on the ability (in white rot only) to degrade lignin along with cellulose and hemicellulose. Prior genomic comparisons suggested that the two d...
متن کاملEvaluation of White-rot Fungi for Biopulping of Wood
Ergosterol involves in fungal cell growth as a major component in fungal cell membranes. It can be an indicator that shows the fungal activity, and its content depends on the fungal strains, culture, growth conditions and so on. In this study, fungal activities and growth patterns of three white-rot fungi strains isolated in Korea were evaluated by determination of ergosterol contents during th...
متن کاملInfluence of Carbon Source on Cellulase Activity of White-rot and Brown-rot Fungi
Three white-rot fungi, Polyporus versicolor, Ganoderma applanatum, and Peniopbora “G,” produce an adaptive cellulase complex that can degrade both soluble cellulose (Cx) and microcrystalline cellulose (C1), a highly ordered form of cellulose. Production of Cx and C1 by the white-rot fungi was repressed by simple sugars. Cellualase preparations from three brown-rot fungi, Poria monticola, Lentin...
