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...

This paper reports on photocatalytic decolorization of a hazardous indigo carmine dye solution. The photocatalytic decolorization was carried out in the presence of the catalyst ZnO. The effect of catalyst dose, pH and initial dye concentration on the degradation process has been assessed. The aqueous dye solution was degraded in a photochemical reactor in the presence of UV light (365nm) along...

A bacterial strain GSM3, capable of decolorizing an azo dye Reactive Red 2 was isolated from dye contaminated soil sample collected from Ammu dyeing industry, Bellary, India. Based on phenotypic characteristics and 16S rDNA sequencing, strain GSM3 was identified as Pseudomonas aeruginosa GSM3. Isolate GSM3 showed 97% decolorization of Reactive Red 2 (300 mgL) within 10 h, while maximally it cou...

This study reports decolorization of Rhodamine B and Congo red by a partially purified laccase from Lentinus polychrous Lév. in the presence or absence of 2,2-azinobis (3-ethylbenzothiazoline-6sulfonate) diammonium salt (ABTS) as a redox mediator. The decolorization study showed that about 90% of Rhodamine B could be decolorized within 52 h, whereas Congo red could be decolorized more than 75% ...

The physicochemical characterization of the textile industry effluent collected from Oswal Textile Industries, Ludhiana (Punjab.) India has been carried out and the results showed that the temperature (40°C), pH (8.00), Biological Oxygen Demand (260 mgl –1 ), Chemical Oxygen Demand (790 mgl –1 ), Total Suspended Solids (2000 mgl –1 ), Total Dissolved Solids (7000 mgl –1 and colour over the pres...

BACKGROUND AND OBJECTIVES Synthetic dyes are recalcitrant to degradation and toxic to different organisms. Decolorization of textile wastewaters is one of the major concerns since last decades. Physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. Biological treatments can be more convenient. In the present study, an attempt has been made for de...

Natural dye extracted from Caesalpinia sappan Linn. was applied to a cotton fabric and silk yarn by dyeing process. The dyestuff component of Caesalpinia sappan Linn. was extracted using water and ethanol. Analytical studies such as UV–VIS spectrophotometry and gravimetric analysis were performed on the extracts. Brazilein, the major dyestuff component of Caesalpinia sappan Linn. was confirmed ...

The objective of the presented research was to examine the potential of capillary electrophoresis (CE) for the analysis of structurally different reactive dyestuffs, their activation and posterior hydrolysis, with special focus on optimization of the working conditions. Preliminary, the effect of various additives to the background electrolyte on the resolution improvements versus migration tim...
