In recent years the pollution of water reservoirs has become the leading environmental problem in the world. Eutrophication of water bodies is rapidly increasing due to higher sewage discharge and anthropogenic stress. Biofilm formation in lakes is due to the excessive release of chemicals such as phosphorous and nitrogen. The present study was aimed to evaluate the extent of pollution in the ancient Agasthya Lake in Badami. The investigation pertaining to chemical analysis revealed the higher amount of nitrogen and phosphorous, analysed to be 60 mg/l and 15.5 mg/l respectively. The study was conducted further to use microorganisms isolated from the above said lake for bioremediation of the same. The process deals with the identification of resistant microorganisms from the lake water and the same have been used for the degradation of chemical parameters such as nitrogen and phosphorous. For the very purpose two strains of Pseudomonas species were isolated and used for the remediation studies. Results showed a considerable decrease of the nitrogen and phosphorous contents in the lake water. The Pseudomonas species were showed the high resistant and degraded the nitrogen and phosphorus in the lake water. Pseudomonas species yielded an efficiency of more than 50% degradation of nitrogen and phosphorous Hence the study revealed that the nitrogen and phosphorous chemical parameters of the Agasthya Lake is degraded by the Pseudomonas species and are used for the remediation of the chemical parameters of the lake.
