AB  - Microbial induced carbonate precipitation (MICP) can immobilize metals and reduce 
      their bioavailability. However, little is known about the immobilization 
      mechanism of Cd in the presence of soil cations and the triggered gene expression 
      and metabolic pathways in paddy soil. Thus, microcosmic experiments were 
      conducted to study the fractionation transformation of Cd and metatranscriptome 
      analysis. Results showed that bioavailable Cd decreased from 0.62 to 0.29 mg/kg 
      after 330 d due to the MICP immobilization. This was ascribed to the increase in 
      carbonate bound, Fe-Mn oxides bound, and residual Cd. The underlying 
      immobilization mechanisms could be attributed to the formation of insoluble 
      Cd-containing precipitates, the complexation and lattice substitution with 
      carbonate and Fe, Mn and Al (hydr)oxides, and the adsorption on functional group 
      on extracellular polymers of cell. During the MICP immobilization process, 
      up-regulated differential expression urease genes were significantly enriched in 
      the paddy soil, corresponding to the arginine biosynthesis, purine metabolism and 
      atrazine degradation. The metabolic pathway of bacterial chemotaxis, flagellum 
      assembly, and peptidoglycan biosynthesis and the expression of cadA gene related 
      to Cd excretion enhanced Cd resistance of soil microbiome. Therefore, this study 
      provided new insights into the immobilization mechanisms of Cd in paddy soils 
      through ureolysis-based MICP process.
