AB  - Self-assembled fungus-flexible fiber composite microspheres (SFFMs) were firstly 
      combined with microbially induced calcium precipitation (MICP) in a 
      continuous-flow bioreactor and achieved the efficient removal of fluoride (F(-)), 
      nitrate (NO(3)(-)), and calcium (Ca(2+)). Under the influent F(-) of 
      3.0 mg L(-1), pH of 7.0, and HRT of 8 h, the average removal efficiencies reached 
      77.54%, 99.39%, and 67.25% (0.29, 2.03, and 8.34 mg L(-1) h(-1)), respectively. 
      Fluorescence spectrum and flow cytometry analyses indicated that F(-) content 
      significantly affected the metabolism and viability of bacteria. SEM images 
      showed that flexible fibers and intertwined hyphae provided effective locations 
      for bacterial colonization in SFFMs. The precipitated products were characterized 
      by XRD and FTIR, which revealed that F(-) was mainly removed in the form of 
      calcium fluoride and calcium fluorophosphate (CaF(2) and Ca(5)(PO(4))(3)F). 
      High-throughput analysis at different levels demonstrated that Pseudomonas sp. 
      WZ39 acted as the core strain, which played a crucial role in the bioreactor. The 
      mechanism of enhanced denitrification was attributed to minor F(-) stress and 
      bioaugmentation technology. This study highlighted the superiorities of SFFMs and 
      MICP combined remediation and documented a promising option for F(-), NO(3)(-), 
      and Ca(2+) removal.
