Decolorization Of Textile Dyes And Their Effluents Using White Rot Fungi

The ability of four different species of white rot fungi viz., Coriolus versicolor, Termetomyces sp, Pleurotus ostreatus and Schizophyllum commune to remove Azo dyes from aqueous solutions were evaluated in batch culture under laboratory conditions. C. versicolor was found to be the most efficient colour removing species for the three dyes investigated. Maximum removal capacity of C. versicolor for acid green, disperse red and basic orange was 98, 76 and 61% respectively. Glucose as the carbon source in growth medium was more suitable for the decolouration of dyes in comparison with starch at the same concentration. Preliminary studies indicate that C. versicolor has the potential to remove colour from aqueous solutions and may be used as an efficient biological agent for the decolouration of dyes in industrial effluents.
