In the present study the treatment efficiency of O3 and UV+O3 processes were compared for the oxidation of simulated dyebath effluent containing a mixture of a reactive dye (C.I. Reactive Blue 19) and various dye auxiliary chemicals. The color, COD and TOC removal rates were assessed for different processes. The effect of initial dye concentration and presence of sodium hydroxide and sodium car...

A bacteria strain Bacillus thuringiensis RUN1identifiedby 16s RNA gene phylogenetic analysiswas used to decolorize malachite green, a triphenylmethane dye in simulated wastewater. The ability of the organism produce extracellular laccase and degrade were also investigated. Results showed that decolorized (84.67 ± 1.19 %) green at 40 mgl-1 within 6 h; decolorization was associated production by ...

A potential bacterial strain PMS82, capable of degrading an azo dye Acid orange as a sole source of carbon was isolated from common effluent treatment plant of Ankleshwar, India. The 16S rDNA sequence and phenotypic characteristics indicated that an isolated organism as Bacillus megaterium PMS82. This strain exhibited complete decolorization of Acid orange (100 mg/L) within 16 h, while maximall...

The application of synthetic dyes in various industries improved the aesthetic properties of the products, but the discharge of dye-containing effluent into water bodies leads to serious environmental problems. Till date, colour removal from effluent is still a challenge due to the absence of economically attractive treatments. In this study, decolourization of a synthetic dye – Remazol brillia...

A dye-decolorizing bacterium was isolated from a soil sample and identified as Bacillus thuringiensis using 16S rRNA sequencing. The bacterium was able to decolorize three different textile dyes, namely, Reactive blue 13, Reactive red 58, and Reactive yellow 42, and a real dyehouse effluent up to 80-95% within 6 h. Some non-textile industrially important dyes were also decolorized to different ...

We report here the development, validation, and use of three real-time PCR assays to quantify the abundance of the following three groups of tetracycline resistance genes: tet(A) and tet(C); tet(G); and tet genes encoding ribosomal protection proteins, including tet(M), tet(O), tetB(P), tet(Q), tet(S), tet(T), and tet(W). The assays were validated using known numbers of sample-derived tet gene ...

Currently used textile dyes are not highly toxic or carcinogenic, but the intense and persistent color of effluent is problematic. Of remediation processes investigated, adsorption process attractive, carbonaceous adsorbents (CAs) ideal for that purpose because their very high dye-binding capacity (DBC). In this review, potential biomass-based feedstocks to produce CAs application produced remo...
