Abstract
Degradation and decolorization of azo dye Golden Yellow HE2R was carried out by soil bacterial isolates. Soil samples from various places were collected and acclimatized for decolorization of azo dye Golden Yellow HE2R. The acclimatized culture GY-B could decolorize 90% of the dye with 10,000 mg/L concentration. Eight promising isolates were able to decolorize the dye solution more than 83.43% averagely in less than 24 hours. Percent decolorization was studied by spectrophotometry. Hyperinteractions between carbon source like 1% glucose, 1% starch and 1% yeast extract and bacteria to decolorize the dye was investigated and modelled. In percent COD reduction studies, it was observed that more than 75% COD was reduced after decolorization process. The decolorization of the dye in half strength nutrient broth was also studied. The products formed after the degradation process were analysed by GC-MS technique.
