Abstract:

The main objective of this investigation is to detoxify the water insoluble dyes like Vat Blue 66 which is other very difficult to decolorize. Wastewater from the textile and other dyestuff industries contain significant amount of synthetic dyes that require prior treatment to prevent groundwater contamination upon being discharged. The microbial decolorization and degradation of dyes has been of considerable interest biological treatment of the wastewater containing dyes. Pseudomonas desmolyticum NCIM 2112 and Bacillus megatherium NCIM 2087 was able to decolorize indole based dye Vat Blue 66 at pH 9, at 25oC. The addition of glucose and yeast extract in the medium enhanced decolorization process. In this investigation, it has been found that the decolorization of this dye was 70% on an average by oxidative degradation by Pseudomonas desmolyticum NCIM 2112 and Bacillus megaterium NCIM 2087. The decolorization was measured as the decrease in absorbance maxima at 530 nm.
