Biological decolorization of textile dyes from isolated microfungi

In this study, biological decolorization of two textile dyestuff (Benazol black ZN and Cibacron black W-NN) was comparatively studied using 22 microfungi strains isolated from polluted industrial soil areas. The initial dye concentrations in the medium were 250 and 500 mg l(-1). Benazol black ZN was...

Description
Summary:In this study, biological decolorization of two textile dyestuff (Benazol black ZN and Cibacron black W-NN) was comparatively studied using 22 microfungi strains isolated from polluted industrial soil areas. The initial dye concentrations in the medium were 250 and 500 mg l(-1). Benazol black ZN was the best decolorized by Haematonectria haematococca (HH1) (36.0%) and Cibacron black W-NN was the best decolorized by Aspergillus niger (AN1) (33.0%) at 250 mg l(-1) dye concentration. At 500 mg l(-1) dye concentration for two different dyes all microfungi strains used showed weak decolorization rates, maximum 13.0% for Benazol black ZN and 6.0% for Cibacron Black W-NN.
