Fig. 2. Manganese peroxidase activity from the white-rot fungal isolates Trametes versicolor HR131 and Trametes sp. HR577 after bioaugmentation at various culture ages into a 697 mg kg^–1 (dry wt.) pentachlorophenol-contaminated field soil. Pooled 95% error bounds for the means (U kg^–1): culture age main effect ±52; culture age and time ±94; culture age and isolate ±74.
