“…Even though some physical and chemical methods are effective for the removal of high strength organic and inorganic materials, the high cost per unit volume is the major draw back (Amaral et al, 2004;Erkurt et al, 2007;Kandelbauer and Guebitz, 2005).…”

This study focuses on treatment of landfill leachate in column experiments by immobilized Trametes versicolor on polyurethane foam, collected from Nonthaburi landfill site, Thailand. In this study, glucose was used as a co-substrate. The effect of biomass growth on color removal was observed by immobilizing fungi on polyurethane foam. The same immobilized fungi were used for four cycles of 5 days each to find the reuse of fungi. Leachate was diluted to see the effect of organic loading on color removal. At optimum pH of 4 and in 20 days with 3 g/L of glucose, the fungi could decolorize 78 % and 63 % for 5-times dilution and concentrated leachate, respectively, using immobilized fungi after 4 days initial growth. Fungi could also reduce biological oxygen demand and chemical oxygen demand of 52 % and 42 % (with initial biological oxygen demand and chemical oxygen demand of 48,900 and 96,512 mg/L), respectively, with glucose 3 g/L in concentrate leachate and with 4 days initial immobilization of fungi on polyurethane foam. About 1-6% higher color removal was observed on day 20 with 15 days fungi immobilization initially as compared to 4 days immobilization. Higher removal efficiency was observed for the same leachate after dilution due to reduction in organic loading. Addition of co-substrate enhances significantly removal of color, biological oxygen demand and chemical oxygen demand. Chemical oxygen demand removal reached to 0.6 mg/mg of biomass with the co-substrate. Therefore, white rot fungi can be considered as potentially useful microorganisms in landfill leachate treatment.

“…These shows that concentration is an important factors in dye biodegradation. Erkurt et al (2007), investigated the effect of time or incubation period including prior to inoculation, during the exponential phase of growth after 3 days, during stationary phase of growth after 5 days or after 6 days of culture. Found that incubation period greatly affect degradation percentage and this agree with the present study.…”

The release of azo dyes especially methyl red into the environment is of great concern due to coloration of natural water, toxicity, mutagenicity and their biotransformation product. Economical and bio-friendly approaches are needed to remediate dye contaminated waste water from various industries. In this study, Staphylococcus aureus capable of degrading azo dye was isolated from waste dump site. The isolate was studied for their ability to decolorize Methyl Red (MR) using UV spectrophotometer at 430 nm at 3 different concentrations (250, 500 and 750 mL) under aerobic condition for the period of 12 days. The 62, 58 and 50% methyl red decolorizations were recorded in 750, 500 and 250 mL dilution respectively at the end of 12 day. The results of this study suggest the potential of Staphylococcus aureus for the treatment of waste water containing methyl red.

“…There are several publications concerning degradation of RB 19 with ozone oxidation [23], using three white rot fungi named as Pleurotus ostreatus (P. ostreatus), Coriolus versicolor (C. versicolor) and Funalia trogii (F. trogii) [6], ozone-enhanced electrocoagulation [5], tropical Brazilian basidiomycetes fungi [27]. However, no publications were found enzymatically about RB 19 dye degradation by HRP enzyme at different circumstances before.…”

“…The treatment of wastewaters containing dyes is complex and expensive. Methods such as chemical and electrochemical oxidation, membrane processes, coagulation-flocculation, adsorption or ion exchange are recommended [6,7]. Some of these have already been used in practice, whereas others have only been tested in laboratories or applied on a small scale [4,8].…”

Aim: Fenolic compounds are major of pollutants in medicine, food and local matrixe. The enzyme peroxidase is known for its capacity to remove phenolic compounds and aromatic amines from aqueous solutions and also to decolorize textile effluents. In this study, decolorization of anthraquinone dye, Reactive Blue 19 (RB 19), large quantities of which used in textile and other industries was investigated using Horseradish peroxidase (HRP) at different conditions. In addition, decolorization efficiency of dye by enzyme was studied in the presence of denaturing agent urea and salt in synthetic wastewater. Material and Methods: Horseradish peroxidase and Reactive Blue 19 were obtained by commercial way. The enzymatic decolorization of the dye was examined by UV-Vis spectrophotometer measurements. Decolorization studies were performed by varying parameters such as enzyme and dye concentrations, pH, temperature, incubation time, presence of H 2 O 2 , salt and urea. Results: Optimum pH value for dye decolorization was determined as 5.0. Maximum dye was removed within 5 min after the beginning for every experiment. After 5 minutes of treatment, the color removal of dye was ca. 90-95% at pH 5.0 and all temperatures. Furthermore, the higher concentrations of dye, H 2 O 2 and NaCl did not exhibit inhibition effect but the initial decolorization rate decreased with increasing the urea concentration. The kinetic constants of enzyme were determined for dye.
