ABSTRACT

 

Considering the fact that azo dyes are recalcitrant and escape in the traditional biological waste treatment procedures, present study explores decolorization and biodegradation of azo dyes by bacteria as an eco-friendly approach. Isolated strain of Bacillus boroniphilus showed appreciable ability of decolorization of reactive yellow 145 dye and exhibited maximum decolorization in static condition of growth. Further, biodegradation of azo dye was analyzed by TLC, UV-Vis spectrophotometry and FTIR, results showed that–N=N- (azo bond) get converted into –NH2 (amino group), which proves accomplishment of biodegradation of reactive yellow 145. Moreover, phytotoxi- city study revealed the less toxic nature of decolorized products as compared to original dye.
