Fig. 1. Laccase activity from the white-rot fungi 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. Error bar is the 5% LSD calculated from the SED. Pooled 95% error bounds for the repeated measures ANOVA factor means (U kg^–1): culture age main effect ±140; time and isolate effect ±130; culture age and isolate effect ±190.
