A new wood preservative based on polymerized complexes of aminotriazole with copper acetate
1998 - IRG/WP 98-30169
This paper presents the results of preliminary fungitoxicity tests as carried out on new polymerized complexes of aminotriazole with copper acetate (PCC) against Coniophora puteana and Trichoderma viride. Laboratory tests on wood confirmed the findings arrived at in the screening test on agar medium. Deep penetration into pine wood of compounds studied was observed and particularly so at humidity...

Comparison of the agar-block and soil-block methods used for evaluation of fungitoxic value of QAC and CCA wood preservatives
1994 - IRG/WP 94-20039
The modyfied agar-block and soil-block methods were used for comparing the fungitoxic value of QAC and CCA type preservatives against Coniophora puteana and Coniophora olivacea The mass loss and moisture contents of wood were analysed....

Proposed degradation pathway for quaternary ammonium compounds by mould fungi
1996 - IRG/WP 96-10166
One group of chemicals that has attracted considerable attention as potential wood preservatives are the quaternary ammonium compounds (QACs). Based upon results of previous research this study confirmed the degradation pathway employed in QAC-tolerant fungi. For this experiment the two dialkylammonium compounds didecyldimethylammonnium chloride and dioctyldimethylammonium chloride were used. QAC-...

Fungitoxic effect of the quaternary ammonium compounds preservatives against Basidiomycetes by using agar-plate and agar-block methods
1996 - IRG/WP 96-30118
Results of investigations on the fungitoxic value of three versions of wood preservatives based on the quaternary ammonium compounds (lauryldimethylbenzylammonium chloride, lauryldimethyl-benzylammonium bromide and alkylbenzyldimethylammonium chloride) and borates in relation to the wood destroying fungi have been presented. The agar-plate (screening) and agar-block method were applied. A wide ran...

Bioremediation of surfactant contaminated waste
1996 - IRG/WP 96-50070
The objective of this work was to determine the potential of fungi as agents for the bioremediation of wastes (particularly wood and soil) contaminated with quaternary ammonium compounds (QACs). Until now only bacteria have been investigated for this purpose. Tolerant strains of Gliocladium roseum and Verticillium bulbillosum were studied for their ability to degrade the following QACs: didecyldim...

Biological resistance of didecyl dimethyl ammonium tetrafluoroborate (DBF)-treated wood in soil-bed and Basidiomycetes tests
2006 - IRG/WP 06-30393
This study evaluated the decay resistance of treated wood with a new quaternary ammonia compound, didecyl dimethyl ammonium tetrafluoroborate (DBF) in laboratory soil bed and Basidiomycetes tests. Treated sugi sapwood specimens with DBF at various concentration levels were first subjected to soil bed tests using two types of soil. The specimens subjected to soil bed tests were then used for Basidi...
