AB  - Fluoride ions (F(-)) and phenol in groundwater have become a great hurdle to the 
      pursuit of a healthy drinking water source. This study established a 
      microencapsulated immobilization reactor with Aquabacterium sp. CZ3 for the 
      simultaneous removal of nitrate (NO(3)(-)-N), calcium (Ca(2+)), F(-), and phenol 
      from groundwater with 100%, 67.84%, 88.67%, and 100% removal efficiencies, 
      respectively. The three-dimensional mesh structure of microcapsules facilitated 
      the transport and metabolism of substances, while their synergistic effect with 
      bacteria promoted the removal of contaminants. F(-) was removed by 
      co-precipitation to generate Ca(5)(PO(4))(3)F and CaF(2) and adsorption. On one 
      hand, the phenol toxicity promoted the production of extracellular polymers and 
      improved the tolerance of bacteria; on the other hand, the degradation of phenol 
      provided a carbon source for bacteria and promoted the denitrification. The 
      development of microencapsulated immobilized reactor provided a clear mechanism 
      for phenol and F(-) removal under the microbially induced calcium precipitation 
      (MICP) technique, while providing a valuable solution for the treatment of 
      complex groundwater resources.
