An efficient microbial technique for decolorizing distillery wastewater was achieved using irradiated spores of Aspergillus fumigatus. The fungus was isolated from soil samples taken from the local distillery processing unit. By using the irradiated spores, wastewater decolorization increased by 14.3% as compared to that of the control treatment (68.8% vs. 54.5%). In the presence of sodium nitr...

abstract background: at present study, acid modified banana leaf ash was used as an adsorbent for the successful removal of reactive black 5 (rb5) dye from aqueous environments. materials and methods: the effect of various operating parameters such as ph of solution, dye concentration, contact time, adsorbent dosage, and the temperature was investigated. results: maximum adsorption capacity of ...

background: in this study, adsorbentn process performance was assessed using nickel oxide nanoparticles for wastewater treatment containing mono azo orange ii dye in a laboratory scale. methods: the effects of various factors such as adsorbent dosage, contact time, ph and initial dye concentration were investigated. findings: based on the obtained results, the optimum ph range to dye removal is...

We developed a new screening method for potential wood preservatives based on decolorization of the dye Remazol Brilliant Blue R by extracellular oxidative agents produced by wood decay fungi. Oxidative biodegradation of lignin yielded decolorized zones around and under fungal cultures on a dyed agar medium. Inhibitory effects were detected by direct observation and measurement of the decoloriz...

Titanium dioxide (TiO2) and Fe3O4 magnetite particles were coated on spherical Kissirises; glucose oxidase (GOx) enzyme was immobilized on Kissiris/Fe3O4/TiO2 by physical adsorption. This catalyst was analyzed by a scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and energy dispersive X-ray (EDX) measurements. The performance of the prepared biocatalyst in the...

The photocatalytic decolorization of aqueous solutions Brown NG, a commercial textile dye, was studied using titana Degussa P-25 as a catalyst for the first time. The experiments were carried out in a batch reactor with the use of artificial light sources (UV-C). The effects of various process variables on decolorization performance of the process have been investigated. The photodegradatio...

Halophilic and halotolerant microorganisms are good candidates for decolorization of azo dyeswhich are routinely used in the dyeing process in textile industries. In this paper, theoptimization of biological decolorization of synthetic dye solutions containing Remazol Black Bby the previously isolated halophilic bacterium Halomonas sp. D2 is investigated. In a primaryinvestigation using a one-f...

Nowadays the treatment of environmental pollutants such as synthetic dyes (used in multiple industries paper, textile, food, plastic and pharmaceutical) has received much attention, especially for biotechnological treatments using both native artificial enzymes. In this context, many enzymes have been reported to efficiently perform dye degradation. Peroxidase is one enzyme, which causes degrad...

In radioimmunoassays and radioassays for various constituents of serum, color quenching is a source of error when liquid-scintillation methods are used in samples that contain hemolyzed blood and samples from jaundiced patients. A quench correction can be made by using the External Standard Channels Ratio method and normalizing the ratios, or, alternatively, by chemical decolorization with tetr...

Twenty-two azo dyes were used to study the influence of substituents on azo dye biodegradability and to explore the possibility of enhancing the biodegradabilities of azo dyes without affecting their properties as dyes by changing their chemical structures. Streptomyces spp. and Phanerochaete chrysosporium were used in the study. None of the actinomycetes (Streptomyces rochei A10, Streptomyces ...
