The potentials of white-rot fungi to decolorizing azo dyes and organic components of textile effluents


MS Shinkafi, IU Mohammed, AA Audu

Synthetic dyes released by various textile industries are a source of concern to environmental safety. Existing physicochemicalrnmethods of dye removal from effluents suffer setbacks like high operational cost, low efficiency and large amount of sludgerngeneration. Over the last two decades considerable work has been done with the goal of using microorganisms as remediation agentsrnin the treatment of dyes containing wastewaters. Microorganisms are capable of removing dyes due to their high metabolic potentialsrnand one of the best organisms that is known to display these wonderful features are the white-rot fungi. In this present study werndemonstrate successfully using white-rot fungi (Phanerochaete chrysosporium) for this purpose and the role of each culture in therndecolorization process was elucidated. The effect of temperature, pH, concentration, mean weight (g) and optical density were studiedrnafter every 48hrs in 12 days period. The enhancement of the degradation was effected by UV-radiation. The adsorption capacity ofrntextile waste effluent and reactive dyes i.e. Congo red and Direct blue 80 was determined spectrophotometrically by monitoringrnabsorbance of different dyes at constant wavelengths (╬╗max). The shift in the absorption maxima in decolorizing samples indicatedrnthe ability of the fungus to degrade dyes and this can be exploited for bioremediation of dyes and their derivatives containing wastes.
