This study was conducted to improve the ability of indigenous New Zealand white-rot fungi to remove @entity211 ( @entity212 ) from contaminated field soil. The effects of different bioaugmentation conditions on @entity212 removal and extracellular enzyme expression were measured in the laboratory. The conditions were fungal growth substrate and co-substrate composition, culture age, and @entity9266 addition to the contaminated soil. The fungi used were Trametes versicolor isolate HR131 and Trametes sp. isolate HR577. Maximum @entity212 removal was 70% after 7 wk from a 1043 mg kg(-1) @entity212 -contaminated soil inoculated with an 11-d-old fungal culture of T. versicolor isolate HR131. There was minimal production of undesirable pentachloroanisole by the fungi. @entity9266 addition had no affect on @entity212 removal. Poplar sawdust was more suitable as a fungal growth substrate and a co-substrate amendment for @entity212 removal and extracellular enzyme expression than the locally available pine and fir sawdust. @entity211 removal was not necessarily correlated with extracellular enzyme expression. The research results demonstrate that @entity212 biodegradation was affected by inoculum culture age, by the presence of a co-substrate amendment, and by growth substrate composition after white-rot fungal bioaugmentation into @entity212 -contaminated field soils.
