摘要：

Crude Manganese Peroxidase (MnP) preparations from the fungus Bjerkandera sp. BOS55 were tested for their abilities to bleach and delignify oxygen delignified Eucalyptus Kraft pulp in a sequence combining a chelating and a peroxide stage. The inclusion of the enzymatic treatment in the bleaching sequence helped considerably to improve the final brightness. Other interesting results included moderate Kappa reduction, slight yield loss and paper sheets with an acceptable breaking length and burst index.
