Azodyes, as used in textile, paper, food, leather, cosmetics and pharmaceutical industries, are major environment pollutants. Existing chemical and physical methods are not able to remove these recalcitrant dyes completely. But microbial methods, on the other hand, have the potential to decolorize as well as completely mineralize these azodyes. Moreover these methods are inexpensive, ecofriendly and are applicable to a large range of azodyes. This chapter focuses mainly on bacterial methods for decolourization and degradation of azo dyes. Different bacterial strains give optimum result at different physiological conditions. Also, different strains use different enzymes for decolourization as well as degradation. Individual strains as well as consortia can be used for the decolourization and degradation. We summarize the bacterial strains isolated, enzymes identified, general mechanism of action and methods involved in decolourization and degradation of these dyes.
