The effect of astrazone red fbl textile dyes on antioxidative system of Phanerochaete chrysosporium

Environmental pollution, in respect of its level of harm, is perhaps one of the mostimportant basic problems in all over the world. The most important factor which hasenhanced this problem is the technological advancements that we have in the last 40-50years. A numerous amount of polluting substances are disposed to natural resources inan uncontrolled manner. Due to this, all livings have been subjected to different?xenobiotic?? or toxic substances. And some of these substances are textile dyes.Metabolites, formed as a result of biodegradation of textile paints can be carcinogenic,mutagenic or toxic materials.Antioxidant protection system, made up of enzymes of the living such as catalase(CAT), glutathione reductase (GR), glutathione S-transferase (GST) , has function forprotection from these xenobiotic and toxic materials as well. These enzymes are thestrong biomarkers of oxidative stress formed in cell.In this work the effect of different concentrational of textile dyes on the differentseasonal Phanerochaete chrysosporium and how antioxidant system is affected havebeen investigated and changes in CAT, GST, GR enzyme activities and in total level ofGSH have been determined. An induction in CAT, GST and GR activity in the earlyphase of low concentration (20 ppm) paint application and GSH level, and an inhibitionin the late phase have been determined. Enzyme activities in the early and late phase ofhigh concentration (50 ppm) paint application and inhibition in total GSH level havebeen determined.KEYWORDS: Textile dye pollution, antioxidant enzymes, astrazone red,Phanerochaete chrysosporiumii
