Fig. 7. Pentachlorophenol removal over 3 wk by the white-rot fungal isolates Trametes versicolor HR131 and Trametes sp. HR577 after bioaugmentation at different SAFI ratios (co-substrate amendment and fungal inocula ratio) into three pentachlorophenol-contaminated field soils. The error bars represent Fisher's least significant difference, * = significance at the 5% level, = significance at the 10% level.
