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

Maulin P Shah, Patel KA, Nair SS and Darji AM

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, and 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 decolourization was 6.0 and 37°C, 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.
