The suspended bacterium community could enhance the biodecolourization of many kinds of azo dyes using bromoamine acid (BAA) as a redox mediator, the optimum conditions for Acid Red 3R were as follows: pH 6-9, glucose, BAA and initial dye concentrations 400-600 mg/L, 19-34.2 mg/L and...

The dye that has been chosen for this study is the monoazo dye. Some of the azo dyes, xanthene dyes and anthroquinone dyes are known to be very toxic and mutagenic to living organism. These chemicals alter the physio - chemical parameter of the water (pH, Biological Oxygen Demand-BOD, ...
Azocolourants and Azodyesare one group of synthetic dyestuffs based on nitrogen that are often used in textile industry. Some AZO dye stuffs may break down under certain conditions to produce carcinogenic and allergenic aromatic amines. Azocolourants and Azodyes and REACH annex XVII Azocolourants ...

Cells of Enterobacter cloacae were immobilized by entrapment in calcium-alginate beads. Immobilized bacterial cells were able to reduced azo bonds enzymatically and used as a biocatalyst for decolourization of azo dye Congo red. Michaelis–Menten kinetics was used to describe the correlation between ...

Dyes come in variety of shapes and are used in transparent applications such as colored glass and vehicle tail lights. Dyes are classified as azo, perinon, quinolone, and anthraquinone. Dyes demonstrate better dispersion than pigments [5,19,21]. Show moreView chapterExplore book Evolution of ...
