AB  - Pseudomonas sp. Y1, a strain with superior synchronous removal ability of ammonia 
      nitrogen (NH(4)(+)-N), phosphate (PO(4)(3-)-P), and calcium (Ca(2+)) was 
      isolated, with the removal efficiencies of 92.04, 99.98, and 83.40 %, 
      respectively. Meanwhile, the chemical oxygen demand (COD) was degraded by 
      90.33 %. Through kinetic analysis, the optimal cultivated conditions for 
      heterotrophic nitrification-aerobic denitrification (HNAD) and biomineralization 
      were determined. The growth curves experimental results of different nitrogen 
      sources indicated that strain Y1 could remove NH(4)(+)-N through HNAD. The 
      results of excitation-emission matrix (EEM) proved that the appearance of 
      extracellular polymeric substances (EPS) promoted the precipitation of phosphate 
      minerals. Finally, the characterization results of the bioprecipitates showed 
      that the HNAD process produced the alkalinity required for microbial induced 
      calcium precipitation (MICP), resulting in the removal of PO(4)(3-) via 
      adsorption and co-precipitation. This study provides a theoretical basis for the 
      application of microorganisms to achieve synchronous nutrient removal and 
      phosphorus recovery in wastewater.
