Textile effluents are among the most difficult to treat wastewaters, due to their considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile wastewaters. In the present study fungal biomass of Aspergillus niger and Humicola grisea were used for the biosorption of basic fuchsin dye from aqueous solutions. The maximum biosorption percentage of 46.09% and 32.66% were observed at 100 ppm concentration of dye by Aspergillus niger and Humicola grisea, respectively. The biosorption capacity of basic fuchsin dye by Aspergillus niger biomass was more efficient than the biomass of Humicola grisea. Adsorption of dye by Aspergillus niger followed Langmuir isotherm model while by Humicola grisea followed Freundlich isotherm model.
