  The assessment of basic blue 41 textile dye decolorisation using the Fenton process: response surface methodology optimisation and toxicity evaluation

  Tanyol, Mehtap; Cikcikoglu Yildirim, Nuran; Tatar, Sule; Serdar, Osman; Yildirim, Numan

  The biochemical biomarkers (Catalase (CAT), glutathione s-transferase (GST), cytochrome P4501A1 (CYP1A1450) activities and glutathione (GSH), malondialdehyde (MDA) levels) of D. polymorpha exposed to the basic blue 41 (BB41) solutions for 24 and 96 h before and after the Fenton process (FTP) were evaluated to investigate the efficiency of the FTP. The optimum conditions for the removal of BB41 were set using central composite design (CCD), which is a response surface methodology (RSM) module in the Design-Expert® software. The optimal conditions were found to be 27.87 min, 3.49 mg/L, and 0.04 for reaction time, initial BB41 concentration, and Fe2+/H2O2 molar ratio, respectively, resulting in maximum (99%) removal efficiency. After FTP, the MDA and GSH levels decreased significantly during the 24 and 96 h. CAT activities were increased after treatment. No statistically significant changes were observed in the CYP1A1 levels after FTP. GST activities decreased during 24 h but increased during 96 h after FTP. CYP1A1450, catalase, GST activities and MDA, GSH levels of D. polymorpha are useful biomarkers to evaluate the efficiency of FTP. This study suggests that BB41 dye must be further treated after the FTP to minimise the ecotoxicological risk.

  Phanerochaete chrysosporium as a model organism to assess the toxicity of municipal landfill leachate from Elazığ, Turkey

  Yildirim, Numan; Yildirim, Nuran Cikcikoglu; Tatar, Sule; Alp, Hevidar

  In order to evaluate the potential ecological risk and the toxic effect of landfill leachate (LL), Phanerochaete chrysosporium was exposed to LL and their biochemical response was observed by using antioxidant parameters. Phanerochaete chrysosporium, ME 446, was kept at 4 °C after being sub-cultured at 28 °C on Sabouraud Dextrose Agar (SDA). Superoxide dismutase (SOD), catalase (CAT) activities, and malaondialdehyde (MDA) and glutathione (GSH) levels of P. chrysosporium exposed to different dilution rates of leachate (1/10 and 1/20) for 24 and 96 h were analyzed by using the ELISA method. The physiochemical parameters such as pH, conductivity, total dissolved solids (TDS), dissolved oxygen (DO), chemical oxygen demand (COD) of leachate, and reference water were analyzed by using the YSI Professional Plus handheld multiparameter meter. In this study, SOD activities were decreased in the application groups compared with the Control Group at the 24th and 96th hours. CAT activities and GSH levels increased in the application groups compared with the Control Group at the 24th hour but decreased at the 96th hours. MDA levels increased in all of the application groups when compared with the Control Group for both 24 and 96 h. Different concentration of LL induces oxidative stress in P. chrysosporium, increased CAT activity and MDA levels, and decreased SOD activity and GSH levels.
