BIOSORPTION OF REACTIVE DYE FROM TEXTILE INDUSTRY EFFLUENT BY ASPERGILLUS FUMIGATUS

K. KALAIARASI AND A. LAVANYA

Abstract

Reactive dyes are important chemical pollutants from textile industries. The dye decolorizing fungal strain was isolated from reactive dye effluent contaminated soil. It was identified as Aspergillus fumigatus based on lactophenol cotton blue staining. A.fumigatus could tolerate and biosorp reactive dye under optimized conditions. Maximum decolorization was observed at 3rd day of incubation at 40ºC and the optimum inoculum concentration was found to be 3% at pH 8. These results suggest that A.fumigatus is more effective for color removal from reactive dye effluent.
