A comparison of the photoefficiency of Ni(II) and NiS incorporated into zeolite P towards photodecolorization of Eriochrome Black T dye solution was investigated in a photocatalytic reactor using UV lamp as a light source. The effect of various experimental variables on the decolorization performance of the process was evaluated by examining catalyst dosage, temperature, initial dye concentrati...
The wastewater released from distilleries and fermentation industries are the major source of soil and aquatic pollution due to presence of water-soluble recalcitrant colouring compounds called melanoidins. Biological decolourisation of of these compounds found more advantages compared to chemical treatments. Hence in this study, the bacterium Pseudomonas fluorescens showing higher decolorizati...
The decolorization and degradation of Direct Blue 71 were investigated using a mono culture of Pseudomonas aeruginosa. The bacterium was able to decolorize the dye medium to 70.43 % within 48 h under microaerophilic conditions. The medium was then aerated for 24 h to promote the biodegradation of the aromatic amines generated from azo bond cleavage. Reduction in total organic carbon in dye medi...
Congo red is a synthetic azo-dye dye with many industrial applications. The effluents containing azo dyes are causing several environmental hazards and thus should be treated prior to their discharge. The present work investigates the possible use of a novel microbial consortium from sheep compost for the decolorization of Congo red dye. The effect of different parameters including contact time...
Article history: Received on: 10/11/2016 Accepted on: 11/12/2016 Available online: 27/02/2017 Six fungal species were isolated from Egyptian soil and identified as Aspergillus flavus, Aspergillus niger, Penicillium canescens, Penicillium crustosum, Penicillium sp. and Fusarium sp. and were tested for their decolorization activity of direct blue dye (DB). Aspergillus flavus and Penicillium canes...
The decolorization of molasses by 17 different fungi in 2 media was studied. Trichoderma viride showed the highest decolorization yield (53.5%) when cultivated at 30ºC for 7 days in Medium 1 which contained the molasses which was diluted to 40 g/L in distilled water. The other Trichoderma species and Penicillium sp. also gave similar results of 40-45%. Decolorization yield was increased by addi...
Image colorization is a new image processing topic to recolor gray images to look as like the original color images as possible. Different methods have appeared in the literature to solve this problem, the way that leads to thinking about decolorization, eliminating the colors of color images to just small color keys, aid in the colorization process. Due to this idea, decolorization is consider...
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...
Current study has evaluated the decolorization of textile dye Red 3BN by Peniciliium chrysogenum, Cladosporium sp. and Aspergillus niger, isolated from textile industry effluent at Bangalore. The organisms were maintained in the laboratory in Potato Dextrose Agar medium. Production of the enzyme laccase by all the 3 strains of fungi has been confirmed through guaiacol bioassay followed by decol...
This study aims to investigate the anaerobic degradation kinetics of reactive dye, C.I. Reactive Red 141 (Evercion Red H-E7B) by partially granulated anaerobic mixed culture using three carbon sources, namely modified starch (MS), polyvinyl alcohol (PVA) and acrylic size (AS) during batch incubation. There is a first-order kinetics reaction in the decolorization processes using MS and PVA as ca...
