Synthetic dyes are widely used in textile, paper, food, cosmetic and pharmaceutical industries. The textile industry accounts for two thirds of the total dyestuff market. During dyeing process approximately 10-15% of the dyes used are released into the wastewater. In the present study Achromobacter xylosoxidans GRIRKNM11 isolated and sequenced from the textile dye effluent site was able to decolorize the turquoise blue dye (100 mg/L) within 48 h at 37°C and pH 7.0. Decolorisation was assayed using spectrophotometery and products formed during degradation were characterized through FTIR spectra.
