Efficient removal of coomassie brilliant blue R-250 dye using starch/poly(alginic acid-cl-acrylamide) nanohydrogel

Criticism of the use of Coomassie Brilliant Blue G-250 for the quantitative determination of proteins.

The quantitative determination of proteins in biological fluids, using Coomassie Brilliant Blue G-250, was evaluated. Compared with the biuret method, the Coomassie Blue G-250 method needs a much shorter time for analysis and has a greater sensitivity. The sensitivity of the dye for albumin is significantly greater than for globulins. The standard curves for the biuret method are more linear th...

Evaluation of the Coomassie Brilliant Blue G-250 method for urinary protein.

The Coomassie Brilliant Blue G-250 method for protein in urine has been evaluated for analytical accuracy and clinical applicability. Extremely simple to perform, the test exhibits good precision and sensitivity. The color developed per gram of protein is protein-type dependent, so no single protein standard is completely satisfactory. Color intensity is linearly related to concentration up to ...

optimization of dye removal from aqueous remazol brilliant blue r (rbbr) by trametessp. pellets

decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...

Antibacterial effect of brilliant blue food dye

Brilliant blue is largely found in ice cream, canned processed peas, packet soups, blue raspberry flavored products, dairy products, sweets and drinks. It is also used in soaps, shampoos, mouthwash and other hygiene and cosmetics applications (Archived from Florida). This study was aimed to investigate the antimicrobial effects of Brilliant blue on Bacillus subtilis as a gram positive bacterial...
