Abstract
The textile industry, by far the highest user of synthetic dyes, is in need of ecologically
efficient solutions for its colored effluents. Effluents from textile industries are a complex
mixture of many polluting substances such as heavy metals, organochlorine-based
pesticides, pigments and dyes. The wastewater containing dyes are highly colored which can
cause water pollution, because these dyes are mutagenic, carcinogenic, and also cannot be
completely removed by conventional wastewater treatment systems. Therefore, dye-
containing effluents should be treated before disposal and discharge to remove or reduce
toxic substances. Wood decomposing basidiomycetes fungi are well known for their natural
ability to decompose lignin, a highly complex non-phenolic polymer, which also gives them
the potential capacity to degrade a wide variety of complex organopollutants. This
degradative ability of wood decomposing fungi has opened up new prospects for the
development of biotechnological processes to treat textile dye effluents (Lopez et al., 2002).
One promising strategy is the use of white-rot fungal and strains that possess the ability to
decolorize synthetic dyes (Ferreira et al., 2000). This study investigates the synthetic dye
decolorizing ability of some selected Polyporus species to identify the potential candidate
fungal species to treat dye containing effluents from textile industries.
