Decolourisation of Orange II by a wood-rotting fungus

An unidentified basidiomycete fungus known as F29 was found to be able to degrade the azo dye Orange II. The fungus degrades the dye at a high dye concentration, with a fast rate of decolouration, at low glucose concentration and at a temperature close to indoor ambient temperature. The mycelia could be reused several times and still maintain high degradative activity. The use of this method as an economical and practical industrial microbiological process is discussed.
