Efficient decolorization of cibracron brilliant red 3B-A dye by novel white rot fungal consortium was studied in static and shaking conditions using solid state fermentation technology. Daldinia concentrica (DC) and Xylaria polymorpha (XP) consortium showed dye removal efficiency than the individual strains within 5 days. The enzymes analysis revealed significant inductions in laccase (84%), lignin peroxidase (78%) and manganese peroxidase (65%) by the fungal co-culture (DC + XP), Xylaria polymorpha (XP) and Daldinia concentrica (DC) respectively. Enhanced decolorization was recorded when the medium was supplemented with glucose and ammonium nitrate as carbon and nitrogen sources respectively. The GCMS and HPLC analysis of metabolites suggest the different fates of biodegradation of cibracron brilliant red 3B-A dye by DC, XP and DC + XP consortium. The isotherm and kinetic studies revealed the goodness of fit of the experimental data when subjected to Freundlich and pseudo-second order models respectively. Phytotoxicity studies revealed that the biodegradation of the cibracron brilliant red 3B-A dye by the DC + XP consortium and individual strains has also led to the detoxification of the pollutant. This study revealed the effectiveness of white rot fungi in the eco-friendly remediation of dye polluted environment.

UV-vis spectroscopy is a workhorse in analytical chemistry that finds application in life science, organic synthesis, and energy technologies like photocatalysis. In its traditional implementation with cuvettes, it requires sample volumes in the milliliter range. Here, we show how nanofluidic scattering spectroscopy (NSS), which measures visible light scattered from a single nanochannel in a spectrally resolved way, can reduce this sample volume to the attoliter range for solute concentrations in the mM regime, which corresponds to as few as 10 probed molecules.

This study presents the development and characterization of manganese ferrite (MnFeO)-based nanocomposites with graphite oxide (GO) and chitosan (CS) for efficient dye removal from textile wastewater and aqueous solution. Comprehensive characterization was performed using FT-IR, Raman, XRD, BET, SEM, DRS and Zeta potential techniques. XRD analysis confirmed the cubic spinel structure of MnFeO, with characteristic peaks at 2θ = 32, 35, 48, 53, 62, and 64°.

The Type V secretion system, or "autotransporter", is a secretion system that enables bacteria to directly export proteins from the cell interior to the extracellular membrane. mCherry is a second-generation monomeric red fluorescent protein that has an improvement in photostability compared to the first generation of RFP. In this research, we conducted the fusion of the mRFP into the C-terminal domain of EhaA - the translocation domain of the autotransporter protein transport system - to investigate the expression of mRFP on the surface of a model organism commonly utilized in recombinant protein research.

Article Synopsis
- The study explores advanced oxidation processes using metal-organic frameworks (MOFs) to improve the breakdown of synthetic dyes in wastewater.
- Four new MOFs were synthesized, each with different structures and coordination of cobalt ions, and were tested as catalysts for degrading the dye X3B through sulfite activation.
- Results showed that two specific catalysts (1/SO and 4/SO) had much higher efficiency in degrading X3B, while the others were less effective; the processes relied on factors like how well the dye was absorbed and the presence of coordination vacancies in the metal ions.

Precipitation polymerization method was used to synthesize chitosan based poly[chitosan-N-isopropylmethacrylamide-acrylic acid] [P(CS-NI-AA)] microgel particles. Synthesized P(CS-NI-AA) microgel particles were utilized as micro-reactors for the fabrication of silver nanoparticles (AgNPs) inside the structure of microgels through chemical reduction of Ag ions using NaBH as reducing agent. P(CS-NI-AA) and Ag-P(CS-NI-AA) systems were analyzed using various characterization techniques like scanning electron microscopy (SEM), ultraviolet-visible (UV-visible) spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy.
