The dry rot fungus and other fungi in houses. Part 1

Biological detoxification of wood treated with salt preservatives
1992 - IRG/WP 92-3717
The use of microorganisms that are capable to convert chemically fixed inorganic preservative complexes from impregnated wood waste into watersoluble components is investigated. A number of fungi were isolated from deteriorated and initially well-treated wood. They revealed an exceptionally high production of organic acids (pH 2). The fungi were identified and used together with others of the same...

Silicon tetrachloride: A potential wood preservative
1980 - IRG/WP 3133
In its present form, this paper is a preliminary draft of a paper that will eventually be submitted for publication in the Forest Products Journal. We are continuing the work on the effects of silicon tetrachloride on wood and expect to have additional data for the meeting in May 1980. Specifically we are measuring the penetration rate and depth of SiCl4, and we are chemically analyzing the treate...

The influence of fungal species and the level of decay on the mortality and feeding activity of adult Euophryum confine (Broun)
2002 - IRG/WP 02-10448
The mortality and feeding activity of adult Euophryum confine (Broun) (Coleoptera: Curculionidae) are used to establish the substrate conditions most suitable for their rearing. Weevils were allowed to feed on Pinus nigra (Arnold) sapwood blocks, either undecayed or decayed to 10% weight loss ±5% by two brown rots Coniophora puteana (Schum.:Fr.) Karst. and Serpula lacrymans (Wulf.:Fr.) Schroeter...

The effects of copper proximity on oxalate production in Fibroporia radiculosa
2014 - IRG/WP 14-10823
Copper remains a key component used in wood preservatives available today. However, the observed tolerance of several critical wood rotting organisms continues to be problematic. Tolerance to copper has been linked to the production and accumulation of oxalate, which precipitates copper into insoluble copper-oxalate crystals, thus inactivating copper ions. The purpose of this study was to assess d...

Selection of Wood-Rotting Basidiomycetes for Inoculation of an Accelerated Soil Bed Test
2014 - IRG/WP 14-20543
There is a need for a test method that guarantees exposure of treated wood to soil and preservative-tolerant wood-rotting basidiomycetes as standard field tests do not do this reliably. The ability of a range of selected wood-rotting basidiomycetes to grow through unsterile forest soil was investigated in a Mason jar test assembly. None of the white-rot fungi in test grew through this soil. Fou...

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...
