Biodegradation Of Reactive Red M5B Dye Using Bacillus subtilis
نویسندگان
چکیده
Azo dyes are widely used in textile industries. Removal of the color from textile waste water is a striking issue. To curb this issue, biological treatment can be employed rather than physicochemical processes. In this work, Bacillus subtilis is used to degrade the reactive dye – RED M5B. It is found that decolorization was due the action of enzyme peroxidase produced by the organisms during its growth. Optimum conditions for the dye degradation were indentified using response surface methodology. Under optimal conditions, 95% degradation was observed within 40 h of inoculation.

A dye-decolorizing bacterium was isolated from a soil sample and identified as Bacillus thuringiensis using 16S rRNA sequencing. The bacterium was able to decolorize three different textile dyes, namely, Reactive blue 13, Reactive red 58, and Reactive yellow 42, and a real dyehouse effluent up to 80-95% within 6 h. Some non-textile industrially important dyes were also decolorized to different ...
