AB  - This study focused on a novel denitrifying Cupriavidus sp. W12, which can perform 
      microbial induced calcium precipitation (MICP) to remove fluoride (F(-)) under 
      aerobic and anaerobic conditions. Under anaerobic condition, the removal ratios 
      of F(-), calcium (Ca(2+)), and nitrate (NO(3)(-)-N) reached 87.52%, 65.03%, and 
      96.06%, respectively, which were higher than that under aerobic condition 
      (50.17%, 88.21%, and 67.33%, respectively). Higher pH of 8.26 was obtained after 
      120 h of the strain W12 growth under anaerobic condition than that under aerobic 
      condition (7.77). The F(-) removal ratio of 98.20% was predicted by the response 
      surface methodology (RSM). Scanning electron microscopy (SEM) images of anaerobic 
      precipitation were dense and porous. CaCO(3), Ca(5)(PO(4))(3)OH, 
      Ca(5)(PO(4))(3)F, and CaF(2) were determined by X-ray diffraction (XRD) and 
      energy dispersive spectrometer (EDS). Self-aggregation of bacteria and adsorption 
      of biological crystal seeds were the determinant of the precipitates formation. 
      The results of infrared spectrometer (FTIR) and excitation-emission matrix (EEM) 
      showed that anaerobic extracellular polymeric substances (EPS) expression led the 
      proportion of hydroxylapatite in the precipitates increased. As the first report 
      on the anaerobic MICP to remove F(-), it provides a theoretical basis for the 
      remediation of F(-), Ca(2+), and NO(3)(-)-N in groundwater.
