AB  - Pseudomonas sp. HXF1, a strain capable of heterotrophic nitrification, aerobic 
      denitrification (HNAD), and biomineralization was identified and employed for the 
      simultaneous removal of ammonia nitrogen (NH(4)(+)-N) and fluoride (F(-)). It 
      removed 99.2% of NH(4)(+)-N without accumulation of nitrous nitrogen (NO(2)(-)-N) 
      and nitrate nitrogen (NO(3)(-)-N), while removed 87.3% of F(-). Response surface 
      methodology (RSM) was used to study the best removal conditions for NH(4)(+)-N 
      and F(-). The results of nitrogen balance experiments with NH(4)Cl, NaNO(2), and 
      NaNO(3) as single nitrogen sources and amplification experiments of 
      denitrification genes proved that the bacterial strains may remove NH(4)(+)-N 
      through HNAD. The experimental results of Scanning electron microscope (SEM), 
      X-ray photoelectron spectroscopy (XPS), and X-ray diffractometer (XRD) indicated 
      that the way of F(-) removal may be adsorption and co-precipitation. The results 
      demonstrated that the strain HXF1 has great potential in the biological 
      denitrification and F(-) removal of groundwater.
