Production of monoclonal antibodies to fungal metabolites
1986 - IRG/WP 1306
The role of fungal extracellular enzymes in wood biodegradation is incompletely understood. Our lab is beginning a project utilizing monoclonal antibodies to characterize extracellular metabolites of the brown rot fungus Poria placenta Fr. (Cooke). Monoclonal antibody technology takes advantage of the ability of antibody secreting spleen cells from immunized mice to fuse in the presence of polyeth...

Diazenes and some organic complexes of boron as potential fungicides for preservation of wood
1999 - IRG/WP 99-30197
Screening for fungicidal activity represents the first step in searching for new active components with enhanced environmental profile in comparison with traditional wood preservatives. Diazenes, their salts, and the salts of the corresponding semicarbazides, as well as several complexes of boron, were screened for fungicidal activity against wood decay fungi Trametes versicolor, Coniophora putean...

On the changes of natural durability of wood sterilised by gamma radiation
2006 - IRG/WP 06-10571
The preliminary study data of natural durability of wood in lab conditions against rot fungi dependency on different sterilisation method have been presented. In the research, white rot fungus Schizophyllum commune Fr.: Fr. and brown rot fungus Poria placenta (Fries) Coke sensu J. Erikson. on the Scots pine were tested. Cobalt 60Co was used as a gamma radiation source at the dosage of 30 kGy. Cont...

Correlation between modulus of elasticity, mass losses and FTIR spectra of copper treated decayed wood
2006 - IRG/WP 06-10580
The composition of copper-based preservatives will change from copper-chromium to copper-ethanolamine, due to environmental demands. The most important drawback of copper-impregnated wood is the presence of tolerant fungal organisms that have developed an ability to degrade such preserved wood. In order to elucidate these processes, specimens (0.5×1.0×15 cm) made of Norway spruce (Picea abies) w...

Analyses of premature failure of utility poles
2012 - IRG/WP 12-40584
In this study a total number of 18 utility poles of Scots pine (Pinus sylvestris) impregnated with a copper-chromium containing preservative were investigated. They were part of different lower voltage transmission lines in the western part of Germany and failed before predicted minimum service life. All poles in this study were less than 15 years in use. The type of decay and fungi were evaluated...
