Abstract
The dye removal from effluent is one of the most difficult problem faced by the dyeing, paper, leather, pharmaceutical, plastics, photographic, medicine and textile industries. The industrial effluent when discharged without proper treatment causes severe environmental pollution. In the present study, P. citrinum and B.cohni were tested for their ability to degrade the reactive dyes. Various parameters such as initial dye concentration dye to inoculum ratio and contact time were studied. The degradation efficiency was maximum when the dyes were treated with P. citrinum for the period of 12 days with the dye to inoculums ratio of 50%. Induction of ligninlolytic enzyme in the media is believed to be responsible for the decolorization of dyes in the medium. Differential fate of metabolism of the treated dyes was proposed on the basis of FTIR analysis.
