The copper-transporting ATPase pump and its potential role in copper-tolerance
2016 - IRG/WP 16-10859
Copper-tolerant brown-rot decay fungi exploit intricate mechanisms to neutralize the efficacy of copper-containing preservative formulations. The production and accumulation of oxalate is the most widely recognized theory regarding the mechanism of copper-tolerance in these fungi. The role of oxalate, however, may be only one part of a series of necessary components required for this complex mecha...

Untreated and copper-treated wood soaked in sodium oxalate: Effects of decay by copper-tolerant and copper-sensitive fungi
2017 - IRG/WP 17-10888
Copper is widely used as the primary component in wood protectants because it demonstrates a broad range of biocidal properties. However, a key concern with using copper in wood preservative formulations is the possibility for brown-rot basidiomycetes to resist the toxic effect. Many brown-rot basidiomycetes have evolved mechanisms, like the production and accumulation of oxalate, which helps thes...

Effects of exposure time on detection of the behavior of white-rot fungi on Oriental beech wood properties
2017 - IRG/WP 17-10902
The comparison of fungal degradation of Orientalis beechwood by two white-rot fungi was evaluated in this study. Biological, mechanical, and chemical assessments of beech wood were carried out at 30 day interval for 120 days. The results demonstrated that both fungi have greater effects on beech wood during each exposure time. However, Trametes versicolor degraded beech wood more effectively than ...
