Studies on the laccase-mediated decolorization, kinetic, and microtoxicity of some synthetic azo dyes
BACKGROUND Enzymatic elimination of synthetic dyes, one of the most environmentally hazardous chemicals, has gained a great interest during the two last decades. The present study was performed to evaluate the decolorization and detoxification potential of the purified laccase of Paraconiothyrium variabile in both non-assisted and hydroxybenzotriazole-aided form against six azo dyes. RESULTS ...
متن کاملRat skin carcinogenesis by topical applications of some azo dyes.
Groups of 6 male rats were painted twice weekly with 1 ml of a 0.2% solution of an azo dye in acetone. The dyes used were aminoazobenzene, 4-monomethylaminoazobenzene, their 3methoxy analogs, and 4-dimethylaminoazobenzene. In each case, all rats developed multiple skin tumors of histologie types similar to those found in rats treated with other chemical classes of carcinogen. 3-Methoxy-4-monome...
متن کاملThiophene-Based Azo Dyes and Their Applications in Dyes Chemistry
The thiophene-based azo dyes class of azo dyes have generated considerable interest since its discovery 62 years ago. These dyes have come to be applied to a very large number and variety of fibres and have therefore achieved an importance which is probably greater than the weights used would suggest. The connection between dyeing and fastness properties on the one hand and chemical constitutio...
متن کاملComparative studies on decolorization of textile Azo dyes by different bacterial consortia and pure bacterial isolate
A total of 47 bacterial isolates were isolated and screened for their ability to degrade selected azo dyes. Of these, one isolates were chosen for further studies based on their ability to degrade a wide spectrum of dyes efficiently and rapidly and identified as Xanthomonas campestris MTCC 10,108. Several microbial cultures Pseudomonas flourecense, Bacillus subtilis and Rhizobium radiobacter pr...
متن کاملKinetics of anaerobic biodecolourisation of azo dyes.
Kinetics of anaerobic biodecolourisation (methanogenic environment) of four azo dyes (Acid Orange 6, Acid Orange 7, Methyl Orange and Methyl Red) was investigated with regard to their electrochemical properties as well as under variation of dye and sludge concentrations, pH and temperature. Cyclic voltammetry revealed a correlation between the potential of irreversible reduction peak of the dye...
