Background & Aim: Industrial wastewater is one of the most important sources of hazardous pollutant emissions. Having high levels of various dyes, textile wastewater is considered as one of the major environmental pollutants. The aim of this study was to compare the efficiency of almond shell ash as a natural absorbent in comparison to commercial activated carbon in removing basic red 18 dye fr...
1. The reverse selective action attributed to acid fuchsin can be explained on the basis of spore resistance. This action does not apply to the vegetative cells of Gram-positive spore bearers. It cannot be extended to include the Gram-negative spore bearers. 2. The selective action of acid fuchsin is that of an ordinary weak disinfectant and is not comparable to the selective action of the trip...
Over-expression and purification of soluble and functional proteins remain critical challenges for many aspects of biomolecular research. To address this, we have developed a novel protein tag, HaloTag7, engineered to enhance expression and solubility of recombinant proteins and to provide efficient protein purification coupled with tag removal. HaloTag7 was designed to bind rapidly and covalen...
Giles, Charles H. (The University of Strathclyde, Glasgow, Scotland), and Robert B. McKay. Adsorption of cationic (basic) dyes by fixed yeast cells. J. Bacteriol. 89:390-397. 1965.-The adsorption of 10 typical cationic dyes on formalin-fixed yeast cells has been studied by determining isotherms, and the results are consistent with an ion-exchange mechanism. The adsorption on this complex substr...
Biosorption is becoming a promising alternative to replace or supplement the present dye removal processes from dye wastewaters. Based on the results of batch studies on biosorption of the dyes on powdered fungal biomass, Aspergillus niger, an immobilised fungal biomass was used in column studies for removal of four dyes, Acid Blue 29, Basic Blue 9, Congo Red and Disperse Red 1 from aqueous sol...
