Abstract
A method to measure laccase and lignin peroxidase (LiP) activity at 40 8 nm (402-410 nm) using 1-hydroxybenzotriazole (HBT) was developed. Th e assay can be performed either as a kinetic measurement or as a stopp ed reaction using 5 mM Na-azide which improves the spectrum. Only whit e-rot fungal laccases and LiP were found to oxidize HBT to give should ers or peaks at 402-410 nm. Phanerochaete and Phlebia manganese peroxi dases did not give absorbance increase at 402-410 nm.
