Forty-six pulp-bleaching fungi were screened for production of key enzymes for conversion of polychlorinated dibenzo-p-dioxins--lignin peroxidase (LiP), manganese peroxidase (MnP), and manganese-independent peroxidase (MiP)--under various conditions that would allow their utilization in the environment. Of 38 MnP-producing strains with MiP
