Determination of absorption, accumulation and transport of copper in mycelium of some wood decay fungi
1999 - IRG/WP 99-10323
Copper compounds are common wood preservatives. However, tolerance of some wood decay fungi to copper compounds has been observed recently. Therefore, we tried to elucidate possible causes of this phenomenon. We investigated uptake, accumulation and secretion of copper in the mycelium of potentially copper tolerant fungi (Antrodia sp.) and non tolerant fungus Trametes versicolor. We observed that ...

Utilization of nitrogenous substance by Serpula lacrymans
1989 - IRG/WP 1397
When Serpula lacrymans degrades wood, the fungus is considered to have to assimilate nitrogen, which is not abundant in the wood, from the third material. The strands/mycelium has grown into the soil under the floor of the wooden house damaged by the dry rot fungus. The authors analyzed the soil samples collected from the ground under the floors of the dryrotted houses. The samples which were coll...

The Copper Tolerance of Mycelium vs. Spores for Two Brown Rot Fungi
2002 - IRG/WP 02-10422
The copper tolerance of two brown rot fungi, Gloeophyllum sepiarium and Oligoporus placentus, has been tested using both mycelia and basidiospores as inoculum sources. Mycelial growth of O. placentus on agar medium was shown to be much more tolerant to copper (as copper sulfate) than that of G. sepiarium. However, there was no difference in copper tolerance of basidiospores between the two specie...

A comparative analysis of Coniophora olivacea (Fr. ex Pers.) Karst. and Coniophora puteana (Schum. ex Fr.) Karst. test strains
1993 - IRG/WP 93-20004
Investigations were carried out to compare pure cultures of Coniophora olivacea (Fr. ex Pers.) Karst. used as a test fungus in Australia and other Pacific countries, and Coniophora puteana (Shum. ex Fr.) Karst. which is used in Europe. Comparisons included morphology, growth rate and dry mass of mycelium, decay capacity, influence of temperature, toxic value of CCA and quaternary ammonium compound...

Uptake of copper by mycelium of wood decay fungi growing on copper S-substituted thioglycolate containing nutrient media
1998 - IRG/WP 98-10291
Mycelia of Trametes versicolor, Coniophora puteana and Poria monticola were grown on potato dextrose agar (PDA) media, containing various concentrations of copper N,N-dimethyldithiocarbamoylacetate (which may be regarded as a copper S-substituted thioglycolate). The tested copper compound revealed relatively low fungicidal activity. After 13-18 day growing period, we determined concentrations of a...

Effect of fumigation with Sulfuryl Difluoride on wood inhabiting fungi, a laboratory test
2006 - IRG/WP 06-30410
Special methods are necessary for the control of wood destroying organisms in the preservation of monuments and historic buildings because of the conservation of their originality and uniqueness.
The control of wood destroying organisms can be realized with conventional liquid wood preservatives or alternative methods. One of these methods is the fumigation. One fumigant, which was in the past of...

Accelerated Above-ground Testing of Wood Preservatives
2007 - IRG/WP 07-20358
The Canadian wood preservation industry is interested the introduction of new preservative formulations, some of which are intended only for above ground uses. Canada’s Pest Management Regulatory Agency requires data from field tests under Canadian conditions but these can take many years to generate results. Forintek has therefore developed an accelerated above ground test, under contract to a ...

Sensitivity to Copper of Basidiospores from Copper Tolerant Fungi: Fomitopsis palustris and Oligoporus placentus
2010 - IRG/WP 10-10707
Copper continues to be an important fungicide in wood preservation. It is the primary component of the preservatives that have replaced chromated copper arsenate for treated wood in residential construction in North America. However, a co-biocide is normally needed to protect against copper tolerant organisms. Previous work has shown that the spores of at least one copper tolerant fungus, Oligopo...

In Vitro Growth of the Basidiomycetes Physisporinus vitreus strains in various conditions in comparison with some white rot fungi
2022 - IRG/WP 22-10987
The paper has preliminary test results to select Pysisporinus vitreus fungal strains for further experiments in a large research project on copper tolerance of P. vitreus by chemotropic test, choice test, and agar plate toxicity tests and determination of the effect of various ions on oxalic acid secretion by these white rot fungi. In the project, it is also aimed to run fungal decay tests to dete...

Evaluation of different wood by-products for sustainable building biomaterial production using fungal mycelium
2022 - IRG/WP 22-50373
As human population increases, the demand for new innovative, sustainable, and low impact construction materials also grows. Mycelium-based composites have shown to be an excellent alternative for traditional products ranging from low-density objects to semi-structural applications. They also present the advantage of using the waste streams from other productive processes as feedstock, enabling th...
