Screening of Wood-Rotting Fungi for Efficient Decolorization of Draft Pulp Bleaching Effluents

In order to find fungi having high treatment activity of kraft pulp bleaching (E1) effluent without any additional nutrietns, 124 strains of white-rot fungi were isolated from decayed wood samples. The author isolated five fungi(KS-62, MZ-400 , YK-719, YK-472 and Phanerochaete sordida YK-624) having high-decolorization activity of the E1 effluent. Particularly, the fugus KS-62 show the high effect of the decolorization and the degradation of the chlorinated lignin in the E1 , effluent compared with Coriolus versicolor and Phanerochaete chrysosporium.
