Description :
The present study was carried out for biodegradation of dye by using test organisms T. hirsuta and WRF-Isolates. Decolorization is an important step in the degradation of the Dye and complete decolorization was achieved by the organisms when the pH of the medium was in a range 4.0-4.5.During the incubation period in the decolorization process by the microorganisms, namely T. hirsuta and WRF-Isolates always showed a decrease in the pH from the initial condition indicating the release of the degradation products. Solid state decolorization was observed to be faster (Maximum 95% with WRF Isolates) compare to the aqueous state decolorization process. In aqueous state decolorization process, WRF isolate were showed faster decolorization of congo red (77.28 % Decolorization) and Methylene Blue (70.67%) while T. hirsuta one of the well known culture for dye decolorization showed less decolorization within five days (CR- 69.10% and MB- 65.34%). The finding in the present study can serve as an important base for the development of a economical as well as simplified biological treatment system using microorganisms for providing reusable clean water for industrial purpose.
