Abstract

Manganese and manganese peroxidase (MnP) are considered essential for kraft pulp biobleaching by white rot fungi. However, biobleaching of EDTA extracted eucalyptus oxygen delignified kraft pulp by the white rot fungus Bjerkandera sp. BOS55 does not require Mn. Fungal organic acid metabolites (e.g. oxalate and glycolate) added to the Mn-free culture medium were found to be stimulatory for brightness gains, delignification and MnP production.
