The ambient conditions present in the contaminated site shows the values: pH (6.61), Temperature (35.6), Moisture (50.72%), Nutrients; Nitrogen (0.41%), Phosphorus (27.87 mg/l), and Sulphur (993.5 mg/l) respectively. The biological parameters studied indicate Dissolved Oxygen (4.58 mg/l), Biological Oxygen Demand (4.62 mg/l), Chemical Oxygen Demand (146.1mg/l).The microbial consortium identified was found to survive and multiply in the present environment conditions. Microbial consortium was sequenced and compared using BLAST, ClustalW and PHYLIP. In order to identify potential microorganism, microbial consortium was exposed to increasing concentration of Tributyl Phosphate viz. 10, 25, 50, 75 and 100 mg/l in MSM, the potential microorganism was found to survive at higher concentration and utilized it as a sole source of carbon. This organism was identified as Pseudomonas pseudoalcaligenes strain DSM 50018T using 16S rRNA sequencing. This organism was found to have high potential for degradation of Tributyl Phosphate present in Low Level Nuclear Waste.
