Dye degrading efficiency of bacteria isolated from Cow dung in Trichy District. Four different bacterial strains Enterobacter sp., Klebsiella sp., Serratia sp., and Bacillus sp. were isolated. The dye degrading efficiency was ranging between 24.03% to 61.52%. As the days of incubation were increasing from 1 to 7 days the degradation efficiency was also increasing to a greater extent. When compared to all the bacterial isolates Bacillus sp. is a highly promising agent, which could act as an efficient dye degrader. Because, from the first day onwards, the degradation was high (34.10%), and after that, at every day incubation the degradation was increasing profoundly. 46.31%, 54.26% and to a maximum of 98.44% at the end of 7 days. Almost hundred % of degradation was effected by this isolate. The entire cell Supernatants also showed equal dye degrading ability. FT –IR, HPLC results confirmed that, the complex, toxic azo dyes are degraded in to simple, non toxic compounds. Due to the removal or the complete degradation the environment is protected from Azo dyes.
