Summary: A halo-thermophilic bacterial consortium capable of decolorizing azo dye under high salinity and temperature conditions was enriched in this study, with Bacillus identified as the dominant genus playing a key role in the decolorization process. The consortium demonstrated effectiveness in decolorization of metanil yellow G across a wide range of pH values, temperatures, dye concentrations, and salinities. Additionally, various enzymes such as laccase, manganese peroxidase, lignin peroxidase, and azoreductase were found to be involved in the decolorization process, with a proposed pathway for decolorization based on GC-MS and FTIR results.

Summary: Mycoremediation of textile effluents, such as synthetic dyes, is an effective and eco-friendly method. Dyes discharged from industries like textile, food processing, chemical, leather, dyestuff, dyeing, and pharmaceutical can negatively impact the natural ecosystem. Lentinus squarrosulus AF5, a strain of fungus, has been identified as a potential decomposer of these dyes. Proteomic analysis revealed differential protein expression in the strain when exposed to the dyes, indicating the important role of extracellular peroxidases in the decolorization process. UV-Visible, FTIR spectroscopic, HPLC, and LC-QTOF-MS analyses confirmed the degradation of the dyes by Lentinus squarrosulus AF5.

Summary: In this study, nitrogen-doped graphene (NG) was found to significantly accelerate the decolorization of methyl orange (MO) azo dye by sulfide. The stagnant time of MO decolorization was remarkably reduced in the presence of NGs, particularly those with graphitic nitrogen. Doping nitrogen improved the electron conductivity and enhanced the interactions between sulfide and carbon atoms bonded to graphitic nitrogen, leading to the formation of reactive intermediate polysulfides.

Summary: In this study, PDPA was used as an inductor layer to stabilize the radical cation in the P3HT polymer matrix. Interphases between P3HT and PDPA films were prepared electrochemically on different electrodes, showing different stabilities depending on the synthesis conditions and electrode materials. This research demonstrates the impact of PDPA induction in stabilizing the semiquinone and quinone forms in P3HT layers, compared to interfaces solely formed by homopolymers on different electrodes.
