Abstract: Wood is one of the most sustainable and versatile building materials available. If protected from biological degradation, wooden structures can provide years of service. Basidiomycete fungi, specifically brown-rot decay fungi, cause the greatest economic loss to wood products in-service. Pressure treatment with chemical preservatives is most often used to extend the service life of wood products and structures. Most current preservative treatments for exterior or in-ground applications are copper-based. Exposure to copper is effective at inhibiting most fungal species through oxidative damage, enzyme inhibition, nutrient transport interruption, protein denaturation, and cell death. However, a subset of brown-rot fungi has been identified as “copper-tolerant” because they are able to tolerate high concentrations of copper and can degrade copper-treated wood. These copper-tolerant fungi represent a major source of economic loss.
