The aim of the present study was to isolate halophilic and halotolerant Actinomycetes with azo dye decolorization ability. To this purpose, different strains of halophilic and halotolerant Actinomycetes isolated from effluent of a textile industry and those received from microbial bank of IBRC were screened on the Remazol Black B for finding dye decolorizing ones. Two strains, M18 and M77, revealed the best decolorization results and effect of different factors including NaCl (0-15%), Temperature (25-40 °C), and pH (5-11) in static condition on their decolorization ability were studied. The best decolorization results on Remazol by Black B by M18 and M77 were at 12.5 and 2.5-10%, pH values of 7-9, and temperatures of 35 and 40 °C, respectively. According to the ability of strains to decolorize the mixed azo dyes, they can be good options for degrading azo dyes in textile effluents.
