Fig. 4. Laccase and manganese peroxidase (MnP) activity from the white-rot fungus Trametes sp. HR577 after bioaugmentation with various co-substrate amendments into a 1043 mg kg^–1 pentachlorophenol-contaminated field soil at a constant (50:50) co-substrate amendment to fungal inocula ratio (SAFI ratio). Pooled 95% error bounds for the means (U kg^–1): MnP and laccase main effects, wood, SAFI ratio and corn grits ±30 and ±90, respectively.
