Removal of a Reactive Dye (Red RB) by the Bacterial Species Isolated from Dyeing Industry Effluents

Removal of reactive dyes from aqueous solution was investigated using bacterial species from dyeing industry effluents. The decolorization was achieved at different dye concentrations, pH and temperature. It was caused by bacterial species such as Enterobacter sp. (GS5), Escherichia coli (GS3) and Bacillus sp. (GS10) and their consortia. More reliable and effective decolorization rates were obtained with 100% Enterobacter sp. (GS5) after 96 hours at 10 and 20 ppm. Decolorization has been maximum in the static experimental conditions.
