DECOLORIZATION OF TEXTILE DYES BY NEWLY ISOLATED TRAMETES VERSICOLOR STRAIN
Öz
In this century, the amount of industrial produces and their consumption has increased tremendously.
Along with this increase, accumulation of industrial waste and its effect on nature has caused serious problems. Because of including various chemicals and especially dye, textile waste water is one of the most hazardous industrial wastes. Color is the most important pollutant in waste water and it should be decolorized. Decolorization is more important than degradation of organic substances from waste water. Even a small amount of dye found changes the color of rivers, lakes and other water
resources, and reduces the penetration of light and solubility of gases.White rot fungus are used as a biological system in degradation and decolorizing of textile dyes. In this study, parameters for decolorization of several textile dyes (Blue 49, Orange 12, Orange 13, Red 31, Black 5, RBBR) by newly isolated Trametes versicolor M96was studied. It has been determined that pH, amount of inoculum, shaking speed (rpm), dye concentration and temperature are important factors in decolorization of the studied dyes. The maximum decolorization was found pH 4.5, amount of inoculums 50 ml, shaking speed 200 rpm, dye concentration 50 mg/l and heat 30 °C.
