The reaction products formed during the decolorization of the sulfophthalocyanine textile dyes Reactive blue 15 (RB15) and Reactive blue 38 (RB38) by the white-rot fungus Bjerkandera adusta were analyzed by high-performance liquid chromatography with diode array detection and with liquid chromatography-electrospray ionization-tandem mass spectrometry. Sulfophthalimides (SPI; 3 and 4) were ident...

Synthetic dyes, azo dye in particular, are widely found in the effluents from textile industries. The persistence and toxicity of these compounds cause adverse impact in the receiving streams. A mixture of isolated cultures, from domestic sewage treatment plant was found to decolourize reactive azo dyes, Red RB, Blue M2B and Yellow, efficiently in the absence of added external nitrogen source. ...

A specific feature of anthraquinone dyes (AD) is to mimic the adenine nucleotides ATP, ADP, NAD and NADH, enabling them to act as ligands in interaction with nucleotide-binding sites of several enzymes and receptors. In the present study, the interactions and/or inhibitory effects of eight AD, including Cibacron Blue 3G-A (Reactive Blue 2), Procion Blue MX-R (Reactive Blue 4) and Remazol Brilli...

PURPOSE The present study was performed to investigate the early effects of blue light irradiation of photoreceptors in retinal explant cultures. METHODS Murine retinal explant cultures were irradiated with visible blue light (405 nm) with an output power of 1 mW/cm2. Dihydroethidium was used to determine the production of reactive oxygen species. Morphological alterations of photoreceptor ou...
