DECOLORIZATION AND BIODEGRADATION OF DYES BY ASPERGILLUS TERRELIS GROWN ON WHEAT STRAW WITH MN PEROXIDASE ACTIVITY

G. EMTIAZI

Abstract

Aspergill us terreus isolated from rotten wood decolorized several dyes used in textile industries, including Sofamine blue, Solamine yellow, Salamine red. Solamine scarlet, Terter direct orange, Terter direct blue and Anilin blue. Decolorization was favoured when the Aspergillus terreus was grown on wheat straw with cellulase and Mn peroxidase activities. This fungus could biodegrade these dyes and utilize them as the only source of carbon, nitrogen and energy. The COD removal and production of ammonia during biodegradation of dyes by the isolated fungi were investigated.
