Three nitrate degrading bacteria, namely S1, S2 and S3 strains, were isolated from soil samples collected from agricultural sites at Polonnaruwa, Oruwala and Gampaha, Sri Lanka respectively. Among the isolated strains, S1 showed a maximum nitrate removal rate of 4.20±0.08 mg/L/day whereas S2 and S3 showed nitrate removal rates of 3.45±0.57 mg/L/day and 3.72±0.19 mg/L/day, respectively.
