Abstract：A high efficient aerobic denitrifier was isolated from rice field to dispose the rural domestic sewage,then the strain was identified and its nitrogen removal effect was analyzed.The results showed that the strain was identified as Pseudomonas monteilii through analyzing the cell morphology,colony morphology, physiological and biochemical characteristics combined with 16S rDNA sequence.The preliminary study on ni-trogen removal conditions of rural domestic sewage showed that with the glucose additive amount of 0.03%, inoculation amount of 0.00015%,rotation speed of 120 r/min and cultural time of 48 hours,the removal rate of TN and NO -2 -N reached 91.55% and 96.33% respectively.
