Abstract

In the present study, an attempt was made to examine the potential of isolated bacterium for decolorization of Remazol Black B dye in batch reactors. A potential bacterial strain was isolated and selected from the textile effluent on the basis of rapid azo dye Remazol Black B (250mgl–1) decolorization and later identified as belonging to genus Bacillus based on phenotypic characterization. The effect of pH, temperature, carbon & nitrogen source was studied with an aim to determine the optimal conditions required for maximum decolorization and degradation. Decolorization was effective at pH 8, 35°C with starch and peptone as carbon and nitrogen sources and in static conditions. This decolorization potential increased the applicability of this microorganism for the dye removal. The results show that the isolated bacterium has a dynamic potential in removal of Remazol Black B dye from wastewater under aerobic conditions.
