In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...
Azo dyes are used in abundance in several industries like textile, printing, paper, plastic, cosmetics, paints, etc. Extensive discharge of such dyes in adjacent water bodies has raised much environmental concern. Azo dyes are toxic to living organisms and their genotoxic and carcinogenic potentials are intensified on being released as mixtures. In the recent years, various microorganisms have ...
Background & Aim: Dyes are one of the most important pollutants in textile wastewater that are toxic, carcinogenic, teratogenic and non-biodegradable. Entering of dyes into water resources reducing the penetration of sunlight and eutrophication is occurred. Melia azedarach core and fruit is one of the inexpensive natural absorbent that has an important place in the treatment of textile wastewat...
Background: Effluents from textile industries contain different types of dyes. One of these dyes used in textile industries is Reactive dye. Because of high molecular weight and complex chemical structures, they show low levels of biodegradability. Hence, the direct disposal of these effluents to municipal wastewater treatment, produce problems in biological treatment processes. The aim of th...
Of 18 commercially used textile dyes, eight were degraded by the white rot fungus,Phanerochaete chrysosporium, by 40 to 73% based on decrease of colour. Both the lignin-degrading enzyme system ofP. chrysosporium and adsorption to its cell mass were involved in the degradation of the diazo dye, Reactofix Gold Yellow. Degradation was best achieved by adding the dye to the medium and then inoculat...
the rate and efficiency of decolorization of dyes likeblue ca, black b133, and corazol violet sr were tested to evaluate white rot fungal strains. trametes hirsuta and pleurotus florida showed the greatest extent ofdecolorization on nutrient salt media. maximum decolorization of 200 mg/l of blue 133 was obtained by 4days old incubated pleurotus florida followed bytrametes hirsuta after 6 days. ...

Phlebia tremellosa decolourised eight synthetic textile dyes (200 mg l(-1)) by greater than 96% within 14 days under stationary incubation conditions. High performance liquid chromatography analysis of culture supernatants indicated that Remazol Black B was degraded by the fungus, however, complete mineralisation did not occur as a colourless organic breakdown product accumulated. Laccase activ...
