Inhibition of the lignin peroxidase of Phanerochaete chrysosporium by hydroxylamino-dinitrotoluene, an early intermediate in the degradation of 2,4,6-trinitrotoluene.

Abstract

The ability of the white rot fungus Phanerochaete chrysosporium to mineralize 2,4,6-trinitrotoluene (TNT) was studied in the concentration range of 0.36 to 20.36 mg/liter. The initial rate of 14CO2 formation was 30% in 4 days at 0.36 mg of [14C]TNT per liter and decreased to 5% in 4 days at 20.36 mg of [14C]TNT per liter. Such a pronounced inhibition was… (More)
