TL;DR: Selenite Brilliant Green Sulfa broths, one prepared from basic ingredients according to formula and brands A and B available in dehydrated form, were compared for effectiveness of recovering salmonellae as mentioned in this paper.
Abstract: Selenite Brilliant Green Sulfa broths, one prepared from basic ingredients according to formula and brands A and B available in dehydrated form, were compared for effectiveness of recovering salmonellae. Distinctly different percent recoveries of salmonellae were achieved among the three types of media.

TL;DR: In this article , the results indicated that the adsorption capacity was dependent on six factors (e.g., contact duration, starting concentration, adsorbent mass, effect of the solution pH, temperature and the effect of KNO3).
Abstract: The multistep chemical modification of carboxymethylcellulose (CMC) in the presence of 4-aminophenazone (A-PH) and multiwall carbon nanotubes (MWCNTs) has been successfully conducted. The environmental performance of this material has been thoroughly investigated. Crystal violet (CV) and brilliant green (BG) were eliminated by utilising a new hybrid nanocomposite material (A-PH-CMC/MWCNTs) from a simulated textile wastewater solution. Using SEM, EDX, XRD and FTIR spectroscopy methods, the detailed characterisation of A-PH-CMC/MWCNT nanocomposites was investigated. The results indicated that the adsorption capacity was dependent on six factors (e.g., contact duration, starting concentration, adsorbent mass, the effect of the solution pH, temperature and the effect of KNO3). In addition, thermodynamic and regeneration studies have been reported. According to the theories of pseudo-second-order kinetics, the removal process involves chemical adsorption. The experimental results were best suited by the Langmuir model, in which maximum adsorption capacities of 20.83 and 22.42 mg g−1 were predicted for the BG and CV dyes, respectively. The research is a preliminary case study demonstrating the excellent potential of A-PH-CMC/MWCNT nanocomposites as a material for CV and BG dye removal.

TL;DR: The purpose of this dual testing procedure was to gain in specificity and to shorten the time required by the completed standard methods, but it did not yield quantitative findings which could be expressed in any reliable way.
Abstract: Interest has increased in recent years in the use of brilliant green lactose bile, as a supplement to or a possible substitute for the standard lactose broth medium of water analysis. This trend has been stimulated by certain negative aspects of the latter medium. Jordan (1) has stressed (a) the too frequent non-specificity of lactose broth for the primary colon group in some waters, (b) its over-sensitiveness in others also suggested by us (2), and (c) the loss of time for control purposes during successive steps of confirmation. To meet these objections, Jordan has suggested planting the two media in parallel. When both are found positive, he regards the finding as specific for the presence of the coli-aerogenes group. If the lactose broth only is positive, however, he recommends another transfer to brilliant green bile, which, if then positive, would again be regarded as specific for the group, whereas if negative, further confirmatory evidence would have to be obtained. The purpose of this dual testing procedure was to gain in specificity and to shorten the time required by the completed standard methods. Of course, it did not yield quantitative findings which could be expressed in any reliable way. Our previous studies with ferrocyanide citrate agar (3) suggested the possible feasibility of converting the well known liquid brilliant green lactose bile medium to a solid form, suitable for direct plating purposes. The outcome of our effort in this direction is the pour plate medium here reported, which is necessarily altered in composition, but contains all the ingredients of the original liquid medium, in concentrations to produce optimum growth of coli-aerogenes organisms. In addition, ferric chloride, erioglaucine, basic fuchsin, and anhydrous sodium sulphite have been added in order to bring

TL;DR: In this article, the effect of temperature on the equilibrium and kinetic adsorption of brilliant green dye by shrimp shell (Macrobrachium rosenbergii) was studied using a batch process.
Abstract: As the direct discharge of dying wastewater into the environment has adverse effects, there is a growing interest in using low-cost adsorbents or waste materials to adsorb dyes. In this study, the effect of temperature on the equilibrium and kinetic adsorption of brilliant green dye by shrimp shell (Macrobrachium rosenbergii) was studied using a batch process. The factors affecting the adsorption process, including contact time, initial dye concentration, and temperature, were investigated. The equilibrium data were analyzed by Langmuir, Freundlich, Temkin, and Dubinin-Raduskevich isotherm models. The Langmuir isotherm model fit the best, and the maximum adsorption capacity values were 8.13, 9.35, and 10.6 mg/g at 20, 30, and 40°C, respectively. The adsorption kinetic data corresponded to the pseudo-second order model at all temperatures. Thermodynamic parameters, such as ∆G, ∆H, and ∆S were calculated. Negative values of ΔG indicated that the overall adsorption was spontaneous. The characterization of surface adsorbent by FTIR confirmed that the shrimp shell can adsorb brilliant green dye and the proposed adsorption mechanisms were hydrogen bonding and n−π interaction. Experimental results showed that the adsorption capacity increased with temperature and the shrimp shell was an effective adsorbent for removing brilliant green dye.
