Methyl red, a synthetic azo dye, was reported for not only being mutagenic but also its persistence has severe consequences on human health, such as cancer, alongside detrimental environmental effects. In the present study, Pseudomonas putida OsEnB_HZB_G20 strain isolated from soil sample to study catalytic activity degradation of methyl red dye. Another strain, aeruginosa PA 1_NCHU used an ele...

The generation of surface anisotropy by photochemical means has been proposed as an attractive method to align liquid crystals. In this paper, we present an experimental study of the alignment induced on a liquid crystal by a polymer film containing azo-dye groups in the side chain. Optical measurements were performed in nematic liquid crystal cells to determine the azimuthal and zenithal ancho...

Unleashing the power of peptide hydrogels for environmental remediation: This is a tale an ultrashort hydrogel (azo-KC) and its efficiency wastewater treatment. The outcome cumulative efforts covalent noncovalent interactions providing unique features like thixotropy insolubility in bulk water medium. Dye contamination from textile industries severe concern pollution, this crosslinked 3D fibrou...

Abstract Shewanella xiamenensis G5-03 was observed to decolorize the azo dye Congo red in synthetic wastewater. The influence of some factors on decolorization efficiency evaluated. optimal conditions were temperature 30-35 °C, pH 10.0, incubation time 10 h, and static condition. kinetic fitted Michaelis–Menten model (Vmax = 111.11 mg L-1 h-1 Km 448.3 L-1). bacterium also able degrade benzidine...

background: the efficacy of nh4cl-induced activated carbon (nac) was examined in order to adsorb rr198, an azo reactive model dye, from an aqueous solution. methods: the effects of ph (3 to 10), adsorbent dose (0.1 to 1.2 g/l), dye concentration and contact time on the adsorption efficiency were investigated. results: the results showed that the removal of dye was highest at a solution ph of 7 ...

In this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (BNNT) has been investigated by quantum calculations. In order to find the preferred adsorption site, different positions and orientations were considered. The impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...

Dyes are the most difficult constituents to remove by conventional biological wastewater treatment. Colored wastewater is mainly eliminated by physical and chemical procedures, which are very expensive and have drawbacks. Therefore, the advantage of using biological processes, such as the biotransformation of dyes, is that they may lead to complete mineralization or formation of less toxic prod...
