To obtain a salt-resistant manganese peroxidase which can be utilized in technical fields such as the enzymatic bleaching of pulp and the dye-degrading treatment of dyeing waste liquids.
An attention was paid on a fact that the manganese peroxidase- producing fungi having been reported had poor sea water salt resistance. Thus, a white decay fungus which produced a salt-resistant manganese peroxidase having resistance against sea water salt was separated from white decay fungi parasitizing in woods immersed in sea water, such as mangrove, or in driftwoods. A strain MG-60 exhibiting the maximum activity among the separated strains had the manganese peroxidase activity of about 5 times that of the strain Phanerochaete chrysosporium having generally been used as a manganese peroxidase-producing strain in the presence of sea water salt. The MG-60 strain can be used to more efficiently carry out the bleaching of unbleached craft pulp and the degradation of synthetic dyes.
