TL;DR: The suitability and selectivity of nutrient broth with bile salts and varying concentrations of brilliant green as an enrichment medium was tested for the isolation of Plesiomonas shigelloides from faeces, finding it most effective at a concentration of 0.001 g/l brilliant green.
Abstract: The suitability and selectivity of nutrient broth with bile salts and varying concentrations of brilliant green as an enrichment medium was tested for the isolation of Plesiomonas shigelloides from faeces. The broth was most effective at a concentration of 0.001 g/l brilliant green, using faeces deliberately contaminated with Plesiomonas. Two hundred and nineteen faecal samples from Nigeria were then examined for the presence of Plesiomonas and other bacterial pathogens. One yielded Plesiomonas following enrichment in bile salts brilliant green broth (BBG broth) whereas no samples were positive on direct plating.

TL;DR: In this paper , the photocatalytic degradations of Thymol Blue and Rose Bengal dyes were investigated at different dye concentrations, illumination periods, solution pH values, and photocatalyst dosages.
Abstract: Nowadays, fast-growing industrialization has resulted in the release of enormous amounts of contaminants such as toxic dyes into water bodies and leading to cause health and environmental risks. In this regard, we prepared inorganic nanocomposites for the treatment of toxic dyes. Hence, we synthesized TiO2/PAni/GO nanocomposites and examined them by using XRD, SEM, TEM, UV–Vis spectroscopy, BET analysis, and a photoluminescence investigation. In addition, band gap energies of the nanocomposites were determined, and Total Organic Carbon (TOC) testing was used to determine dye degradation levels. The photocatalytic degradations of Thymol Blue and Rose Bengal dyes were investigated at different dye concentrations, illumination periods, solution pH values, and photocatalyst dosages. By using TiO2/PAni/GO, TiO2/PAni, and TiO2 at neutral pH, a photocatalyst dose of 1600 mg/L, and exposure to visible light, Thymol Blue and Rose Bengal were photodegraded 85–99%, 60–97%, and 10–20%, respectively, at a concentration of 25 ppm (180 min). Reductions in the TOCs confirmed their photodegradation, and a kinetic study revealed photodegradation followed first-order kinetics. This study shows the coating of polyaniline (PAni) and graphene oxide (GO) on TiO2 improved its ability to photodegrade Thymol Blue and Rose Bengal dye.

TL;DR: A total of 448 clinical isolates and seven reference strains of Candida species were tested for their susceptibility to a group of dyes and chemicals and resistogram patterns obtained were found to be specific for each species.
Abstract: A total of 448 clinical isolates and seven reference strains of Candida species were tested for their susceptibility to a group of dyes and chemicals All strains were also identified by conventional methods The chemicals/dyes used in the disc diffusion tests were brilliant green, janus green, cycloheximide, fast green, rhodamine 6 G, ethidium bromide and 2, 3, 5 triphenyl tetrazolium chloride Sensitivity to the chemicals was coded by a seven-figure code Resistogram patterns obtained were found to be specific for each species The disc diffusion test was found to be inexpensive, quick and gave reliable results within 18 h

TL;DR: In this paper, the results of the adsorption kinetics have proved that the pseudo-second order model correctly describes the adaption phenomenon of the two dyes studied.
Abstract: The aim of this study is to find an effective and inexpensive natural material used as an adsorbent for the textile dyes removal. Indeed, we have been interested in testing the effectiveness of sugarcane bagasse (SB) as a biosorbent to remove brilliant green (BG) and eriochrome black T (EBT). In our experiments, different parameters such as initial dye concentration, contact time, adsorbent dose and solution temperature have been analyzed in a batch system. Similarly, the studies of thermodynamic, kinetic and adsorption isotherm have been evaluated. The sugarcane bagasse (SB) without any modification has been characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The maximum adsorption capacity of BG and EBT on the SB adsorbent has been 37.58 and 12.30 mg.g -1 respectively, for a concentration of 40mg.g -1 at a temperature of 20°C and 1g.L -1 of adsorbent. The results of the adsorption kinetics have proved that the pseudo-second order model correctly describes the adsorption phenomenon of the two dyes studied. The Langmuir and Freundlich isotherms have been applied to experimental equilibrium data. The various thermodynamic parameters such as Gibbs free energy (ΔG°), enthalpy (ΔH°) and standard entropy (ΔS°) have indicated that the adsorption is spontaneous and endothermic in brilliant green and exothermic in eriochrome black T.
