Geographical patterns of denitrifying bacterial communities associated with different urban lakes.

ABSTRACT: The geographical variation of denitrifying bacterial communities and water quality parameters in urban lakes distributed across nine provinces in China were determined. The Illumina sequencing data of the denitrifying encoding gene nirS was examined in the samples collected from nine localities (pairwise geographical distance: 200-2600 km). The results showed that fundamental differences in water quality were observed among different urban lakes. The highest nitrate (2.02 mg L^-1) and total nitrogen (3.82 mg L^-1) concentrations were observed in Pingzhuang (P < 0.01). The algal cell concentration ranged from 1.29 × 10⁸ to 3.0 × 10⁹ cell per L. The sequencing data generated a total of 421058 high quality nirS gene reads that res
