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-...

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...

Isolation and identification of non-decay fungi affecting the performance of alkylammonium compounds
1993 - IRG/WP 93-10020
The isolation of DDAC tolerant fungi was carried out on lumber treated with a range of antisapstain chemicals containing DDAC as one of their active ingredients. The tolerant fungi were selected by using malt media spiked with DDAC (100 and 2500 ppm). Isolations were tentatively identified into a range of fungi commonly found associated with wood deterioration (i.e. Penicillium sp. and Trichoderma...
