TL;DR: In this article, the brilliant green lactic acid medium has a pH value of 7.1-7.3, which is similar to the one we use in this paper.
Abstract: The invention belongs to the field of microbes and relates to a brilliant green lactic acid medium. The brilliant green lactic acid medium comprises EC broth, 2.0g/L of cow bile salt, 0.012g/L of brilliant green, 3.0g/L of manganese sulfate and 15.0g/L of agar. The brilliant green lactic acid medium has a pH value of 7.1-7.3. Each liter of the EC broth comprises 20.0g of tryptone, 10.0g of lactose, 2.0g of monopotassium phosphate, 5.0g of common salt, 1.5g of bile salt NO.3, 4.0g of dipotassium hydrogen phosphate and the balance distilled water. The brilliant green lactic acid medium has a simple formula, can be prepared conveniently, has a low cost, is conducive to popularization application, promotes bacterium fast growth, reduces a variation rate and is convenient for observation and analysis.

TL;DR: Prepn. as mentioned in this paper is by adsorbing human gamma-globulin to finely powdered ion-exchanges resin in buffered saline soln and by colouring with a colouring agent.
Abstract: Prepn. is by adsorbing human gamma-globulin to finely powdered ion-exchanges resin in buffered saline soln. and by colouring with a colouring agent. Adsorption is pref. by warming, and an antiseptic such as thimerosal or sodium nitride is added herein. The soln. is then coloured by a globulin protein colouring agent such as brilliant green, Evans' blue or trypanblue. The soln. is stable and easy in criticism of the resum reaction since gamma-globulin binds more strongly to ion-exchange resin than to latex. In addition, ion-exchange resin used for the present purpose is easily available, cheap and requires no special technique such as ultracentrifugation to select only fine particle.

TL;DR: In this paper, the authors used vacuum ultraviolet (VUV) radiation (185 nm wave length) was used in the presence of atmospheric oxygen as an advanced oxidation technique and the influence of each of the related main parameters was studied, Radiation time, salinity, pH, temperature and radiation intensity.
Abstract: In this study vacuum ultraviolet (VUV) radiation (185 nm wave length) was used in the presence of atmospheric oxygen as an advanced oxidation technique. Six organic dyes were examined as model pollutants ( methyl violet , methyl blue, brilliant green , malachite-green, Remazole blue B and picric acid ). Picric acid as the most persistent one was selected for more detailed kinetic investigations. The influence of each of the related main parameters was studied, Radiation time, salinity, pH, temperature and radiation intensity. Kinetics of the oxidation reaction was studied. COD was also followed up. It follows from the results that vacuum-UV radiation of 185 nm in the presence of atmospheric oxygen is an efficient method for the oxidation process. Four of sex examined dyes were degraded in different rates according to persistency of each pollutant dye. The reaction rates were in the order of: ( methyl violet > methyl blue >brilliant green > remazole > malachite green> picric acid) . In the case of picric acid; the reaction was promoted by rising the temperature, raising or lowering pH above and below pH 7.0, increasing radiation dosage. The rate was inhibited by increasing salinity and buffering. The present technique was found promising in the elimination of the persistent organic pollutants out of the treated water.

TL;DR: In this paper, the effect of alkyl substituents and copolymer composition on optical absorption spectra was studied, and it was shown that copolymers containing immobilizcd dye experience reversible decoloration.
Abstract: Copolymers of MMA, n-butyl-, tert-butyl-, and n-decyl methacrylates with Brilliant Green styrenesulfonate and methacrylate were synthesized. The effect of alkyl substituents and copolymer composition on optical absorption spectra was studied. In the presence of ammonia, the copolymer films containing immobilizcd dye were shown to experience reversible decoloration. For the copolymers with different composition, diffusion coefficients of ammonia were calculated. In contrast to the copolymers, the absorption spectra of the composite films obtained by mechanical mixing of poly(alkyl methacrylates) with Brilliant Green oxalate appear to change with time under UV and visible light irradiation, and no complete recovery of their color upon ammonia desorption was observed

TL;DR: In this paper , the potentiality of coriander leaf to sequester brilliant green (BG) dye from the aqueous phase was investigated and the batch experiments were conducted at two different temperatures, 30 and 40 ℃, with stirring speed of 120.0 rpm.
Abstract: Adsorption process has been performed to investigate the potentiality of coriander leaf to sequester brilliant green (BG) dye from the aqueous phase. Coriander leaf of 75-micron size has been characterized by SEM, BET, FTIR etc. In the present study, emphasis has been given on the removal of BG dye under different conditions viz. dose of biomaterial (10.0 - 100.0 mg), pH (2.0 - 12.0) and dye concentration (10.0 - 100.0 mg/L) by Taguchi optimization. The batch experiments have been conducted at 25 ℃ with stirring speed of 120.0 rpm. The kinetic study is performed at two different temperatures, 30 and 40 ℃. The batch adsorption process for sequestration of the dye followed pseudo-2nd order kinetics (R2 = 0.99). The study also reveals that the Freundlich isotherm is the best fitted (R2 = 0.96) model. The adsorption capacity is 68.49 mg/g and the overall removal efficiency is above 80.0 %. HIGHLIGHTS The coriander leaf (75-micron) has been investigated as an effective adsorbent for Brilliant green dye in aqueous environment Effects of physico-chemical properties of adsorbent (BET, pZC, zeta potential, bulk density, moisture, ash etc.) and the role of several operating parameters (contact time, pH, dose and concentration) have been investigated Langmuir, Freundlich isotherm models and pseudo-second-order kinetic model favour the adsorption phenomena L9 orthogonal array (3X3) of Taguchi optimization study with ANOVA analysis predicts the role of control parameters GRAPHICAL ABSTRACT
