Textile dyes with different chemical structures are consistently used in textile industries and they are being recalcitrant xenobiotic in nature. The aim of present research is directed to finding the preference of striking carbon and nitrogen sources on remazol golden yellow decolorization. Bacterial strains were isolated, screened and tested for dye degradation of remazol golden yellow in bas...

BACKGROUND Fungal manganese peroxidases (MnPs) have great potential as bio-remediating agents and can be used continuously in the immobilized form like many other enzymes. RESULTS In the present study, purified manganese peroxidase (MnP) enzyme isolated from Ganoderma lucidum IBL-05 was immobilized onto polyvinyl alcohol-alginate beads and investigated its potential for the decolorization and...

The removal of dyes from wastewater, is one of the major environmental concerns due to their high color density, and they are toxic at even low concentrations. Adsorption process by advanced oxidation processes (AOPs) has been found to be a more effective method than classical methods for treating dye-containing wastewater. This research, is to investigate the decolorization abilities of az...

The biosorption potential of three fungal waste-biomasses (Acremonium strictum, Acremonium sp. and Penicillium sp.) from pharmaceutical companies was compared with that of a selected biomass (Cunninghamella elegans), already proven to be very effective in dye biosorption. Among the waste-biomasses, A. strictum was the most efficient (decolorization percentage up to 90% within 30 min) with regar...

In this study, the MgCl2/red mud system (MRM) was used to investigate the color removal efficiency of dye solutions. Parameters such as the effect of the dosage of red mud (RM) and MgCl2 have been studied. The effect of pH on the conversion rate of Mg2+ has also been studied. The color removal efficiency of MRM was compared with that of PAC/RM and PAC/NaOH. Meanwhile, the color removal efficien...

Remazol Brilliant Blue R (RBBR) dye was used as substrate to evaluate ligninolytic activity in 125 basidiomycetous fungi isolated from tropical ecosystems. The extracellular RBBR decolorizing activity produced when selected fungi were grown in solid media and in soil contaminated with organochlorines was also evaluated. A total of 106 fungi decolorized the RBBR during the growth in malt extract...

The photo-oxidative decolorization of Direct Red 23 (DR23), a textile dye which is suspected to be carcinogenic was investigated using peroxydisulfate activated by UV irradiation and heat in a batch photo-reactor at experimental conditions. A very simple analytical method, direct UV–vis spectrophotometric detection, was utilized for the progress of photo-oxidative decolorization of dye in aqueo...

a bacterial strain (strain ps) was isolated from the textile effluents carrying serilene black bnfs® (c.i. disp. blk. mix) disperse dye. the isolate was able to decolorize the dye without the need for any exogenous carbon source. full sequencing of its 16s rrna indicated that bacillus sp strain ps is related to bacillus cereus groups.  silica- gel-thin layer chromatography of serilene black dye...

This research investigated the production of porous zinc oxide (ZnO) ceramics obtained by replica method for water depollution photocatalytic processes. Five photo-decolorization cycles were performed to analyze reuse potential ceramics. Statistical analyses using R programming conducted investigate possible significant differences between them. The porosities 46.74 and 62.50% (depending on com...

This study is focused on development of a method of TiO2 immobilization, convenient for the wastewater remediation (especially for the degradation of textile dyes) and cheap for an industrial operation. An influence of selected operational parameters on process performance was verified. Methylene Blue was chosen as the model dye, however, a possibility of decolorization of other dyes was also t...
