Abstract
Pollution is increasing with alarming rate because of rapid industrialization. Textile and dyestuff industries are the major contributors to industrial pollutants, containing dyes. In India, today there are many textile industries which are on the verge of getting closed and some are already shut down due to problem of increasing dye pollution. Bioremediation is a low cost method available for reclaiming the soils, which have been polluted. Many bacterial and fungal species have been studied in this regard. The aim of our study was to isolate and identify the microorganisms from textile industrial effluent and soil, having potential to degrade the dyes present in wastewater. Bacterial isolates from effluent, normal soil and effluent treated soil along with some standard bacterial strains were subjected to decolorize dyes named Bromophenol blue and Coomassie brilliant blue. Also bacterial consortium was used which gave high percentage of decolourization for the dyes. For Coomassie brilliant blue dye Alcaligen, Rhizobacter, P. putida, P. fluorescence showed noticeable decolourization efficiency. P.putida, P.fluorescence, K.aeruginosa and Alcaligen showed degradation efficiency for bromophenol blue dye. The results showed that the bacteria Pseudomonas species i.e. P. putida and P. fluorescence have potential application for bioremediation of dye-polluted water discharged from textile industries.
