Enhanced uptake of wood modification agents in “bioincised” wood
2009 - IRG/WP 09-40445
The permeability of refractory wood species e.g. Picea abies and Abies alba is reduced resulting in a radial penetration of chemical solutions of only a few millimetres. Exploitation of these wood species is therefore not possible for many applications. A novel biotechnological method (European patent 05027812.6) based on the pre-treatment of wood with the white-rot fungus Physisporinus vitreus si...

Modelling hyphal growth of the bio-incising fungus Physisporinus vitreus
2010 - IRG/WP 10-10710
The white-rot fungus Physisporinus vitreus preferentially degrades the pit membranes of bordered pits in tracheids and subsequently enhances wood permeability. Thus, P. vitreus can be used to improve the uptake of wood preservatives and environmentally-benign wood modification substances. This process can be used to enhance the use and sustainability of native conifer wood species by the wood indu...

Analyzing hyphal growth of the bio incising fungus Physisporinus vitreus with light-, confocal laser scanning- and, Synchrotron X-ray tomographic microscopy
2010 - IRG/WP 10-20438
Norway spruce wood is an important building material for the forest and wood industry. To improve wood permeability and uptake of wood modification substances Physisporinus vitreus is employed as a bioincising agent. In this study wood specimens were incubated with P. vitreus to assess hyphal colonisation and structural alterations of Norway spruce wood. After different incubation periods, semi-th...

Fungal laccases as a tool for wood functionalization
2013 - IRG/WP 13-20533
Wood degrading fungi are the most important production organisms for laccase, a promising oxidative biocatalyst with numerous biotechnological applications in the forest products industry. Laccases are multi-copper containing oxidases (EC 1.10.3.2), which catalyse mono-electronic oxidation of phenols, polyphenols and anilines at the expense of molecular oxygen. Interest in these essentially ‘eco...

Environmental Fate of Micronized Copper
2015 - IRG/WP 15-50310
The environmental fate of wood preservatives is an important aspect to estimate the health and environmental impact. Although biocides from treated wood may be released into the soil, water or air, the latter pathway is frequently neglected in favour of leaching studies. Nonetheless, wood dust is well known to cause a variety of adverse health effects, in particular diseases to the respiratory tra...
