Isolation of a wood-rotting fungus to decolorize a wide range of structurally different synthetic dyes

초록

Twenty-one different fungi were tested for their ability to decolorize a wide range of structurally different dyes. Twenty fungal strains were isolated from fruiting bodies which were collected at the Kwangneung National Arboretum, Korea. One fungal strain were isolated from a rotting wood at Soongsil University, Korea. Nine kinds of dyes were used: three anthraquinone dyes and six azo dyes. The five fungal strains, Laetiporus sulphureus, Polyporus arcularius, Auricularia polytricha, Stereum ostrea, and Bjerkandera sp. UK-1 showed decolorization ability. Except Auricularia polytricha, thefourfungal strains were wood rotting fungi, and belonged to Aphyllophorales. Bjerkandera sp. UK- 1, which was a white rot fungus, could decolorize all kinds of dyes tested in this study, indicating this fungus is one of candidates for applying in biological methods of dye waste treatment.
