A consortium-GB containing two microorganisms Galactomyces geotrichum MTCC 1360 and Bacillus sp. VUS was able to degrade sulfurcontaining dye Brilliant Blue G, optimally at pH 9 and temperature at 50 8C. The ability of consortium-GB to work at higher temperature and pH ranges will help in using this consortium for removal of the dye from textile effluent. Malt extract, peptone and beef extract ...

Spectral studies on the interaction of acidic capsular polysaccharide (SPS), isolated from Klebsiella K28, with cationic dye and surfactants have been reported. The polymer induced strong metachromasy(~ 100 nm blue shift) in the cyanine dye pinacyanol bromide (PCYB). The SPS consists of D-glucose, D-galactose, D-mannose and D-glucuronic acid (2:1:2:1) molar ratio) in hexasaccharide repeating un...

Spectral studies on the interaction of acidic capsular polysaccharide (SPS), isolated from Klebsiella K28, with cationic dye and surfactants have een reported. The polymer induced strong metachromasy (∼100 nm blue shift) in the cyanine dye pinacyanol bromide (PCYB). The SPS consists f d-glucose, d-galactose, d-mannose and d-glucuronic acid (2:1:2:1 molar ratio) in hexasaccharide repeating units...

When uninjured cells of Valonia are placed in methylene blue dissolved in sea water it is found, after 1 to 3 hours, that at pH 5.5 practically no dye penetrates, while at pH 9.5 more enters the vacuole. As the cells become injured more dye enters at pH 5.5, as well as at pH 9.5. No dye in reduced form is found in the sap of uninjured cells exposed from 1 to 3 hours to methylene blue in sea wat...

A modified Neuhoff's colloidal Coomassie Blue G-250 stain is reported, dubbed "blue silver" on account of its considerably higher sensitivity, approaching the one of conventional silver staining. The main modifications, as compared to Neuhoff's protocol, were: a 20% increment in dye concentration (from 0.1% up to 0.12%) and a much higher level of phosphoric acid in the recipe (from 2% up to 10%...

In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...

the optimization of process conditions for the degradation of acid blue 193 by uv/peroxydisulfate was investigated using response surface methodology (rsm). the effects of four parameters namely initial k2s2o8 concentration, uv irradiation, temperature, and initial dye concentration on two process responses, color removal and the rate constants of the first-order kinetic equations, were investi...

introduction: in the current study we evaluated the incremental value of lateral pelvic lymphoscintigraphy imaging of endometrial or cervical cancer patients who underwent sentinel node mapping. methods: operable endometrial and cervical cancer patients without clinical or paraclinical evidence of lymph node involvement were included in the study. the day before surgery the patients were sent ...

an agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. the physical properties of the developedadsorbent were characterized using ftir. the study was realized using batch experiments. the effectsof contact time, ph, initial dye concentration, biosorbent dose and temperature were investigate...
