Fig. 1. Laccase activity for the New Zealand white-rot fungal isolates Trametes versicolor HR131 and Trametes spp. HR577 after bioaugmentation into a 697 mg kg ^–1 pentachlorophenol-contaminated field soil at different SAFI ratios (substrate amendment to fungal inoculum ratio). Error bar = the 5% least LSD on the standard error of difference in the means. Pooled 95% error bounds for the ANOVA repeated measures factor means (U kg^–1): SAFI ratio main effect ± 112, time and isolate, and SAFI ratio and isolate effects ± 154, and ± 159, respectively.
