AB  - Contamination by Cd is a significant environmental problem. Therefore, we 
      examined Cd removal from an environmental perspective. Ureolysis-driven calcium 
      carbonate precipitation has been proposed for use in geotechnical engineering for 
      soil remediation applications. In this study, 55 calcite-forming bacterial 
      strains were newly isolated from various environments. Biomineralization of Cd by 
      calcite-forming bacteria was investigated in laboratory-scale experiments. A 
      simple method was developed to determine the effectiveness of microbially induced 
      calcite precipitation (MICP). Using this method, we determined the effectiveness 
      of biomineralization for retarding the flow of crystal violet through a 25-mL 
      column. When the selected bacteria were analyzed using an inductively coupled 
      plasma optical emission spectrometer, high removal rates (99.95 %) of Cd were 
      observed following incubation for 48 h. Samples of solids that formed in the 
      reaction vessels were examined using a scanning electron microscope. The CdCO3 
      compounds primarily showed a spherical shape. The results of this study 
      demonstrate that MICP-based sequestration of soluble heavy metals via 
      coprecipitation with calcite may be useful for toxic heavy metal bioremediation.
