Microbial Degradation of Textile Dye (Remazol Black B) by Bacillus spp. ETL-2012

摘要

In the present study, an attempt was made to examine the potential of isolated bacterium for decolorization of Remazol (azo dye) in batch reactors. Bacteria from soil, & dye waste were subjected to acclimatization with azo dye, in the basal nutrient media. The most promising bacterial isolate was used for further dye degradation studies. Biochemical characteristics revealed the isolated organism as Bacillus spp. The optimum pH and temperature for the decolorization was 6.0 and 37oC, respectively. This decolorization potential increased the applicability of this microorganism for the dye removal. The results suggest that the Bacillus spp. ETL-2012 can be used as a useful tool to treat waste water containing reactive dyes.
