Biodegradation of Azo Dyes
Session
Agriculture, Food Science and Technology
Description
Synthetic dyes are widely used in textile, dyeing, paper, printing, color photography, pharmaceutical, food, cosmetics, and other industries. Azo dyes represent about one-half of all the dyes in common use and are employed as coloring agents in the textile, food, and pharmaceutical industries. Although these are not toxic, but after released into the aquatic environments, they can be converted into carcinogenic amines. Chemical and physical methods including adsorption, coagulation-flocculation, advanced oxidation and electrochemical methods are very efficient in color removal. These methods are quite expensive and have operational problems; high sludge formation, regeneration requirement and cost of adsorbent make adsorption an unattractive method for decolorization purposes. Nowadays the attention is focused on the treatment of azo dyes with biological methods due to these methods are ecofriendly and cost-effectiveness. Azo dye biodegradation by several mixed and monoculture bacterial cultures, aerobic and anaerobic culture, white root fungi, algae, plants have been reported.
