A bacterial strain SVM1 with remarkable ability to decolorization textile dye Reactive Red ME4BL was isolated from the activated sludge soil collected from a common effluent treatment plant (CETP) in Perunduari, Erode district Tamil Nadu. Different parameters such as temperature and pH were optimized for decolorization of Red ME4BL by using isolated bacteria. The most promising bacterial isolat...

White rot fungus Marasmius sp. BBKAV79 (GenBank accession number-KP455496, KP455497) exhibited decolourization and degradation of Navy blue HER dye (concentration 50 mg l-l) within 24 h under shaking condition. In the present study, various investigated parameters like initial dye concentration, pH, temperature, carbon and nitrogen sources were optimized to develop a faster decolourization proc...

The biodegradation of Grey Lanaset G, which consists of a mixture of metal complexed dye, was studied. Experiments were carried out in a bioreactor with retained pellets of the fungus Trametes versicolor that was operated under conditions of laccase production. Although decolorization was highly efficient (90%), no direct relationship to extracellular enzyme was apparent. Moreover, the extracel...

Pseudomonas desmolyticum NCIM 2112 was able to degrade a diazo dye Direct Blue-6 (100 mg l(-1)) completely within 72 h of incubation with 88.95% reduction in COD in static anoxic condition. Induction in the activity of oxidative enzymes (LiP, laccase) and tyrosinase while decolorization in the batch culture represents their role in degradation. Dye also induced the activity of aminopyrine N-dem...

Background and Purpose:Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim was to evaluate the performance nanoscalezero-valent iron (NZVI) in the removal of dye acid red 18 (AR18) from aqueous solutions. Materia...

The batik industry generates large amounts of highly colored wastewater. Azo dyes in wastewater can cause environmental pollution. In this study, synthetic containing 32 mg/L Reactive Black 5 (RB5) and Orange 16 (RO16) was treated by ozonation a 2 L batch reactor. color unit reduced from 4240 to 70 after 10 min below 50 15 (7.3 g O3/m3, 4 L/min). first-order decay constant for determined be 1.1...
