AB  - Bioremediation based on microbial induced carbonate precipitation (MICP) was 
      conducted in Cd-contaminated seleniferous soils with objective to investigate 
      effects of MICP on the fates of Cd and Se in soils. Results showed that soil 
      indigenous microorganisms could induce MICP process to stabilize Cd and mobilize 
      Se without inputting exogenous urease-producing strain. After remediation, 
      soluble Cd (SOL-Cd) and exchangeable Cd (EXC-Cd) concentrations were decreased 
      respectively by 59.8% and 9.4%, the labile Cd measured by the diffusive gradients 
      in thin-films technique (DGT) was decreased by 14.2%. The MICP stabilized Cd 
      mainly by increasing soil pH and co-precipitating Cd during the formation of 
      calcium carbonate. Compared with chemical extraction method, DGT technique 
      performs better in reflecting Cd bioavailability in soils remediated with MICP 
      since this technique could eliminate the interference of Ca(2+). The increase in 
      pH resulted in Se conversion from nonlabile fraction to soluble and exchangeable 
      fractions, thus improving Se bioavailability. And Se in soil solution could 
      adsorb to or co-precipitate with the insoluble calcium carbonate during MICP, 
      which would partly weaken Se bioavailability. Taken together, MICP had positive 
      effects on the migration of Se. In conclusion, MICP could stabilize Cd and 
      improve Se availability simultaneously in Cd-contaminated seleniferous soils.
