Biological Removal of Azo and Triphenylmethane Dyes and Toxicity of Process By-Products
Increasing environmental pollution is connected with broad applications of dyes and imperfection of dyeing technology. Decolourization of triphenylmethane brilliant green and disazo Evans blue by bacterial and fungal strains and toxicity (phyto- and zootoxicity) of degradation by-products were investigated. Influence of incubation method on dyes removal was evaluated (static, semi-static, shake...
متن کاملThe Comparative Study on the Rapid Decolorization of Azo, Anthraquinone and Triphenylmethane Dyes by Anaerobic Sludge
An anaerobic sludge (AS), capable of decolorizing a variety of synthetic dyes, was acclimated and is reported here. The sludge presented a much better dye decolorizing ability than that of different individual strains. A broad spectrum of dyes could be decolorized by the sludge. Continuous decolorization tests showed that the sludge exhibited the ability to decolorize repeated additions of dye....
متن کاملPreparation of ZnO Photocatalyst for the Efficient and Rapid Photocatalytic Degradation of Azo Dyes
Zinc oxide (ZnO) photocatalysts were synthesized by sol-gel method using zinc acetate as precursor for degradation of azo dyes under UV irradiation. The resultant samples were characterized by different techniques, such as XRD, SEM, and EDX. The influence of preparation conditions such as calcination temperature and composite ratio on the degradation of methyl orange (MO) was investigated. ZnO ...
متن کاملAptamers switch on fluorescence of triphenylmethane dyes.
MG and SRB aptamers, which are short RNA sequences originally selected only for binding to malachite green or sulforhodamine B, can greatly enhance the fluorescence of normally nonfluorescent triphenylmethane dyes. MG aptamer enhances the quantum yields of malachite green (MG) and a novel rigidized derivative, indolinyl malachite green (IMG) by >2000-fold. SRB aptamer brightens patent blue V an...
متن کاملRemoval of Triphenylmethane Dyes by Bacterial Consortium
A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial isolates exhibited a remarkable color-removal...
