In this study, the optimization of working cathode position in sleeve-type bioelectrochemical system (BES) was evaluated with inner/outer chamber for azo dye decolorization. Results showed that the working position in outer chamber performed better with decolorization efficiencies of 97.8 ± 2.1% (7h) and 94.0 ± 2.3% (16 h) than that in inner chamber as the volume ratio Vcathode:Vanode=1:1 and 3...

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 d...

Economical and bio-friendly approaches are needed to remediate dye-contaminated wastewater from various industries. In this study, a novel bacterial strain capable of decolorizing triarylmethane dyes was isolated from a textile wastewater treatment plant in Greece. The bacterial isolate was identified as Aeromonas hydrophila and was shown to decolorize three triarylmethane dyes tested within 24...

A study of the aerobic degradation of beet molasses alcoholic fermentation wastewater diluted to 50% (chemical oxygen demand, COD: 82 g/l) was carried out using the following fungi: Penicillium sp., Penicillium decumbens , Penicillium lignorum and Aspergillus niger . These four microorganisms produce a decolorization of the wastewater from the first day of incubation, achieving the maximum deco...

Dyes are the major toxic substances in all industrial wastewater and are highly carcinogenic to human beings and other soil and water living things. In this study, the most efficient bacterial isolate in decolorization of Basic Red 46 dye, isolate A3, was isolated and identified as Enterobacter cloacae sp. under the accession number KP202719. Different parameters such as dye concentration (100 ...

BACKGROUND Sugarcane distilleries use molasses for ethanol production and generate large volume of effluent containing high biological oxygen demand (BOD) and chemical oxygen demand (COD) along with melanoidin pigment. Melanoidin is a recalcitrant compound that causes several toxic effects on living system, therefore, may be treated before disposal. The aim of this study was to isolate a potent...

BACKGROUND AND OBJECTIVES Discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. Keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, Congo red, by a fungal isolate, Aspergillus niger HM11. MATERIALS AND METHODS CENTRA...

The decolorization of industrial dyes was investigated using extracellular enzymes produced by 21 basidiomycetes, mainly edible mushrooms. Among the 27 dyes used in this study, nine were decolorized by over 40%. Most fungi decolorized Acid Orange 20, but they showed different specificities in the case of the other dyes. Determination of activity staining by native polyacrylamide gel electrophor...

The antioxidant properties of Galium verum L. (Lady’s Bedstraw) and Tragopogon pratensis subsp. pratensis (Goat’s beard) methanol extracts, from localities in Serbia were evaluated, through determination of total phenolics and flavonoids content, as well as DPPH • (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, ABTS •+ (2,2-azinobis-(3ethylbenzthiazoline-6-sulfonic acid) radical cation deco...

The study was investigated the decolorization potentials of certan selected microbial species (bacterial) to an actual textile dyeing industry effluent. All the microbes tested namely (bacterial) Bacillus sp, pseudomonas sp, Acineto bacter, Legionella and Staphylococcus (bacterial) showed greater potential in decolorizing the dye effluent. Bacterial decolorization of textile effluents were crit...
