The nitrogen (N) removal characteristics of denitrifying bacterium LZ-14 were investigated in this study. Extensive carbon sources can be used for LZ-14, with acetate as the most effective one. The strain LZ-14 grew fast at a range of 20ºC to 35ºC, and exhibited high N-removal efficiency. Nitrogen removal mainly was performed in the growth phase of 12-36 hr with an amount of nitrite accumulation that was reduced completely in the following 24 hr. The strain LZ-14 was identified as Pseudomonas by PCR amplification and homology analysis of 16S rDNA sequence. Strain LZ-14 was inoculated in simulative constructed wetlands (SCWs) to enhance pollutant removal in pilot-scale, which showed a significant effect on CODCr and total nitrogen (TN) removal.
