Fig. 3. Laccase and manganese peroxidase (MnP) activity form the white-rot fungus Trametes versicolor HR131 after bioaugmentation at various culture ages and two fungal inoculum compositions into a 1043 mg kg^–1 (dry wt.) pentachlorophenol-contaminated field soil with no co-substrate amendment. Pooled 95% error bounds for the means (U kg^–1): MnP culture age main effect ±104 and wood main effect ±85; laccase culture age main effect ±22.
