Abstract:
Release of textile effluent into the environment is a matter of health concern. Dyes and pigments that are part of textile effluent generate hazardous wastes which are generally inorganic or organic contaminants. Among the present pollution control strategies, biodegradation of synthetic dyes by microbes is evolving as a promising approach, even more than physico-chemical methods. While both mixed cultures and pure cultures have been used to achieve efficient biodegradation, no conclusive result has been determined. This paper aims at checking the efficiency of mixed culture of sewage and pure

Abstract:
Biological oxidation of azo-dyes is important for wastewater treatment. Azo-dyes are synthetic organic colorants that exhibit great structural variety. A large majority of these dyes are released into the environment. The textile industry and dyestuff manufacturing industry are two major sources of released azodyes. In the present study, we focus on the anoxic degradation of a disperse azo-dye, p-aminoazobenzene (pAAB), a simple azo-dye, by a pure culture of Bacillus subtilis, growing on a synthetic medium. Bacillus subtilis is a bacterium capable of using nitrate and/or nitrite as terminal el

Abstract:
Biological treatment of wastewaters discharged by the textile industry could potentially be problematic due to the high toxicity and recalcitrance of the commonly-used azo dye compounds. In the present report, the fate of two azo dyes under methanogenic conditions was studied. Mordant Orange 1 (MO1) and Azodisalicylate (ADS) were completely reduced and decolorised in continuous UASB reactors in the presence of cosubstrates. In the MO1 reactor, both 5-aminosalicylic acid (5-ASA) and 1,4-phenylenediamine were identified as products of azo cleavage. After long adaptation periods, 5-ASA was detect

Abstract:
Azo dyes are a popular group of dyes in the printing, food, leather, cosmetic, textile, and pharmaceutical sectors and are the largest and most important group of colored chemicals due to their facile production procedure. It is characterized by the presence of an azo group (-N=N-). The stability of azo dyes makes it recalcitrant. Discharge of untreated waste water that contains colored compounds with azo dye reaches water streams and affects the organisms due to the toxicity of the dyes. Many physicochemical and chemical approaches have been used for the removal of dye from polluted water. Al

Abstract:
Factors affecting biofilm removal of azo dyes from a synthetic, municipal-type wastewater were investigated using lab-scale, rotating drum biofilm reactors. Among the three azo dyes studied - Acid Orange 8, Acid Orange 10, and Acid Red 14 - only AO-8 degraded aerobically. The azo bond cleavage occurred very easily for all three dyes under anaerobic conditions. AO-8 removals ranged from 20% to 90%. Statistically designed experiments were used to characterize the response of pseudo-steady state biofilms. Two AO-8 removal rate maxima were identified - one at high bulk-phase dissolved oxygen and l

La presencia de colorantes azo en aguas residuales provenientes de industrias textiles representa una de las principales fuentes de contaminación en el medio ambiente. Se han empleado métodos fisicoquímicos para la eliminación de estos compuestos, sin embargo, en la actualidad no existe un método que garantice la eliminación total de los colorantes y el problema de contaminación continua presente. Estudios realizados proponen el uso de Pleurotus ostreatus como una alternativa biológica para la degradación de colorantes azo.

Abstract:
Azo dyes in textile industry effluent are one of the major toxic contaminants causing a severe threat to life. Bioremediation is the most cost-effective and environmentally beneficial innovative biotechnologically technique used to mitigate dyes’ toxic effects in aquatic environments. The purpose of the present study was to determine the azo dyes degradation potential of a ciliate, Paramecium caudatum, isolated from industrial wastewater. Under optimum conditions, P. caudatum was found to possess a 90.86% decolorizing ability of RR2 (reactive red), 83.06% of RB5 (reactive blue) and 85.43% of L

Els colorants tipus azo pertanyen al grup de contaminants amb caràcter tòxic i recalcitrant per als processos convencionals que es duen a terme a les plantes de tractament d'aigües municipals. La utilització de materials carbonosos ha resultat beneficiosa per augmentar el rendiment d'aquests processos, ja que actua com a portador d'electrons entre l'oxidació d'una font de carboni secundària i la reducció del colorant azo. Per això, aquest treball planteja l'ús d'un innovador sistema combinant el material portador d'electrons i l'element separador en un mateix element. Això s'aconsegueix mitjan
