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...

In this research, several series of triarylmethane dyes containing one or more terminal methoxy substituents with a variable tertiary amino groups have been used. These dyes have been applied to different substrates by using various methods including transfer printing and then their fastness properties were measured. These dyes shows exceptionally high light fastness (6-7) on acid modified poly...

this study demonstrates the spectral data for two triarylmethane dyes, malachite green (mg) and crystal violet (cv) at room temperature. effects of micellar environment, and crown ether addition on the spectral behaviour of the dyes were studied using absorption spectroscopic method. the dye-anionic surfactant interactions in micellar media were investigated. the chosen surfactants with differe...

The search for safe antimalarial compounds acting against asexual symptom-responsible stages and sexual transmission-responsible forms of Plasmodium species is one of the major challenges in malaria elimination programs. So far, among current drugs approved for human use, only primaquine has transmission-blocking activity. The discovery of small molecules targeting different Plasmodium falcipar...

The crystal structure of two neutral triarylmethane dyes with a p-quinone methide core was determined by X-ray diffraction analysis. The spectroscopic characteristics of both compounds in 23 solvents with different polarities or hydrogen-bonding donor (HBD) abilities has been studied as a function of three solvatochromic parameters (ET(30), π* and α). Both compounds 1 and 2 showed a pronounced ...

Most of the dyes are carcinogenic and mutagenic in nature. Plants potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed design an efficient hydroponic system screen ornamental plant species for removal synthetic solution triarylmethane Methylene Blue (MB) diazo Congo Red (CR). plants selected screening Trachyspermum ammi, Tagetes erecta, Hibis...

Trametes hirsuta and a purified laccase from this organism were able to degrade triarylmethane, indigoid, azo, and anthraquinonic dyes. Initial decolorization velocities depended on the substituents on the phenolic rings of the dyes. Immobilization of the T. hirsuta laccase on alumina enhanced the thermal stabilities of the enzyme and its tolerance against some enzyme inhibitors, such as halide...
