Fungal decolorization of dye wastewaters: a review

In recent years, there has been an intensive research on fungal decolorizat ion of dye wastewater. It is becoming a promising alternative to replace or supplement present treatment processes. This paper examines various fungi, living or dead cells, which are capable of decolorizing dye wastewaters; d iscusses various mechanisms involved; reports some elution and regeneration methods for fungal biomass, summarizes the present pretreatment methods fo r increasing the biosorption capacity of fungal biomass-, discusses the eff ect of various factors on decolorization.
