ABSTRACT:
A bacterium designated as Acinetobacter sp., isolated from domestic sewage soil identified by taxonomic studies by 16S rDNA sequential analysis was found to decolorize azo dye with the decolorization efficiency varying from 80-96%. This strain decolorized 96.2% a deep red sulphonated azo dye Reactive RedC2G29 (200 mg/L) with 1.76 g/L dry cells of specific decolorization rate in static condition at optimum pH 5.0 and temperature 30°C. The degradation efficiency of this strain was within 48 h. Phytotoxicity studies revealed less toxic nature of decolorized products as compared to original dye. HPLC, GC-MS and LC-MS analysis revealed the production of metabolites as final product by degradation of the dye.
