Sequestration of copper ions by the extracellular mucilaginous material (ECMM) of two wood rotting basidiomycetes
2004 - IRG/WP 04-10533
The radial growth rate of colonies originating from either whole or ECMM-free inocula of Coriolus versicolor was investigated. The presence of ECMM allowed colonies to maintain higher growth rates than those form ECMM-free inocula up to 2 mM CuSO4 in the medium. The ECMM of C. versicolor and G. trabeum was able to reduce the diffusion of copper ions in solution. The ‘raw’ ECMM of both fungi ha...

Production of reactive oxygen species in the presence of oxidized iron and oxalate under conditions mimicking brown-rot fungal degradation of wood
2016 - IRG/WP 16-10861
The biochemical role of oxalate in the fungal solubilization of iron is well known, but additional information is needed on the role that oxalate plays in the brown-rot decay of lignocellulose. In this study iron sequestration from iron and iron oxide-hydroxides was assessed with regard to the function of a chelator-mediated Fenton (CMF) reaction and the generation of reactive oxygen species (ROS)...

Make do and mend: Re-using timber in Smithfield Market
2022 - IRG/WP 22-50371
Historic buildings are part of our built environment. They are a record of how construction and use of materials have evolved and provide excellent opportunities for regeneration of urban areas. Moreover, re-using these buildings and as much of the material within, contributes to the Green Revolution.
Currently, there is tremendous growth in green construction and as Bob Dylan once said, “the t...

Keeping wood greenest: Maximizing the unique benefits of preserved wood through end-of-life planning to realize carbon sequestration and a circular economy
2024 - IRG/WP 24-50387
While competitive fuels and different energy sources are a main driver of current difficulties with using end-of-life wood products for fuel, that is a potentially smaller problem than the rapidly changing carbon footprints of competitive materials, which can potentially be smaller than wood, if the wrong decisions are made at the end of life by users and waste generators. While users have several...
