Abstract

Azo Dyes have different applications in industry. Several chemical and physicalmethods have been proposed in removing of these dyestuffs. Alternatively, biological treatment is recognized as economical and environmentally friendly method for Decolorization of dyestuff Wastewaters. In the current research the capacity of the removal of Remazol Black-B and Remazol Red-B by Streptomyces hygroscopicus PTCC1132 in static condition was investigated. An OA layout was constructed with four factors: temperature (28-35° C), pH (6-8), salt concentration (0. 5%-2%) and dye concentration (500-10000 mg/l) at four levels for the experimental design. The design and analysis of Taguchi experiments was performed by Qualitek-4 software. We showed that the Remazol Black-B Decolorization can be significantly improved by Optimization of the factors involved in Remazol Black-B Decolorization by S. hygroscopicus. The optimal conditions were pH 9, temperature 33oC, salt concentration 1% and dye concentration 5000 ppm. Under optimum conditions. Thus, this straine, under the achived effective condition az a result of exprements analysis i. e, temperature 33oC, pH=8, and salt concentration as 1% up to 100% of Azo Dyes(RR-B) with the density of (10000 ppm) will be removed aqueous medium. employing this type of bactria in biological treatment of wastwater with industrial dyes can be of great help in treatment and re-use Wastewater.
