Abstract :
Most commercial synthetic dyes consist of azo dyes which have toxic, carcinogenic and mutagenicproperties. Dyes are widely used in painting and printing processes especially in textile industries.Because of the inadequate chemical and physical treatment techniques used to treat these dyes fromfactory discharge waters, and some oxidant molecules used in chemical treatment methods danger forthe environment, biological treatment is gaining importance. P. ostreatus is saprophyte that lives inalmost all temperate climates; Many trees such as poplar, beech, oak, elm, maple, linden, willow,walnut and chestnut in rotten trunks. It degrades the plant s polysaccharides such as hemicellulose,cellulose and lignin extracellular and uses it as a carbon source. Lignocellulosic enzymes, which can beproduced by a large majority of white rot fungi in general, used to treat dye substances from wastewater. In this study, the biosorption-biodegradation of Direct Black 22 azo dyes widely used in thetextile industry by P. ostreatus fungi, which are used in this study and isolated from Erzincan, and forthis purpose the activities of enzymes of function have been investigated. Also it is aimed to biologicaltreatment of synthetic dye materials which are used in the textile dying industry and which are theimportant pollution factors in the wastewater which are left to the environment. Consequently, it was observed that enzymes such as polyphenol oxidase, laccase, manganese peroxidase and lignin peroxidase gave effective results on the treatment of azo dyes. In particular, the activity of the enzyme laccase has been high. In addition the tried to use different logging waste as a source of nutrient treatment on and It has been determined that tree species that have been saprophyte on P. ostreatus have turned their shell parts into microparticles and used them in the environment of dyeing.
