Abstract
In the presence of K-ferricyanide as oxidant at pH 10, 14C-ring-labelled synthetic lignin (DHP) was covalently coupled to unbleached kraft pulp. This chemically labelled kraft pulp (CLKP) was used in a small scale (30 mg pulp in 1.5 ml buffer) for testing ligninolytic enzymes and mediators for possible use in pulp bleaching. The results from this assay correlated well with laccase/mediator kraft pulp delignification plus TCF-bleaching. The order of release of label from CLKP was: Laccase>lignin peroxidase>Bj. adusta MnP>Phanerochaete MnP. These results are discussed, as well as the possible relationship to oxidation of 20 mM HBT (1-hydroxybenzotriazole) by the above enzymes.
