Synthesis of silver nanoparticles using bacterial exopolysaccharide and its application for degradation of azo-dyes
In this study, the synthesis and characterization of exopolysaccharide-stabilized sliver nanoparticles (AgNPs) was carried out for the degradation of industrial textile dyes. Characterization of AgNPs was done using surface plasmon spectra using UV-Vis spectroscopy, X-ray diffraction (XRD) and Raman spectroscopy. The morphological nature of AgNPs was determined through transmission electron mic...
متن کاملDegradation of azo dyes by laccase and ultrasound treatment.
The goal of this work was to investigate the decomposition of azo dyes by oxidative methods, such as laccase and ultrasound treatments. Each of these methods has strong and feeble sides. The laccase treatment showed high decolorization rates but cannot degrade all investigated dyes (reactive dyes), and high anionic strength led to enzyme deactivation. Ultrasound treatment can decolorize all tes...
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 کاملAzo Dye Biodecolorization Enhanced by Echinodontium taxodii Cultured with Lignin
Lignocellulose facilitates the fungal oxidization of recalcitrant organic pollutants through the extracellular ligninolytic enzymes induced by lignin in wood or other plant tissues. However, available information on this phenomenon is insufficient. Free radical chain reactions during lignin metabolism are important in xenobiotic removal. Thus, the effect of lignin on azo dye decolorization in v...
متن کاملBiodecolorization of textile azo dye using Bacillus sp. strain CH12 isolated from alkaline lake
Textile azo dye decolorizing bacteria were isolated from alkaline Lakes Abaya and Chamo using Reactive Red 239 (RR239) dye. Through subsequent screening process, strain CH12 was selected to investigate the effects of nutrient supplement, DO, pH, temperature, dye concentration and types on decolorization. Based on 16S rRNA gene sequence analysis, strain CH12 was identified as Bacillus sp. Decolo...
