The present study deals with the isolation, identification and screening of bacterial species capable to decolorize variety of dyes. Decolorization of dyes and growth of the bacterial species are investigated. The strain ETL-1942 decolorized all the selected dyes except Remazol Brilliant Blue R, Reactive Blue H5G, Remazol Turquoise Blue G and Fast Green. In our study, we identified three groups of dyes on the basis of the pattern of dye decolorization by strain ETL-1942. The results indicate that decolorization rate is faster for the dyes of the third group than the second group. The strain can grow with all the six dyes tested, but decolorization rates are different for each dye. These results demonstrate that the strain ETL-1942 have ability to decolorize wide range of dyes and therefore further investigation for physico-chemical parameter were carried out.
