AB  - Microbial induced carbonate precipitation (MICP) is known as a significant 
      process for remediating heavy metals contaminated environment. In this study, a 
      novel Cd-resistant ureolytic bacteria was isolated and identified as Enterobacter 
      sp. Its performances for immobilizing Cd in solution and soil were systematically 
      discussed at different treatment conditions. Results showed that initial pH and 
      Cd concentration were important parameters to influence Cd removal rate. The 
      maximal Cd removal rate in solution reached 99.50 % within 7 days by MICP. The 
      precipitation produced in Cd removal process were characterized by X-ray 
      diffraction, scanning electron microscopy and energy dispersive spectrometer to 
      understand the removal mechanism. Analyses showed that Cd removal mechanism of 
      CJW-1 was predominately via biominerals including calcites and vaterites to 
      absorb Cd(2+). Cd immobilization tests demonstrated that the highest 
      Cd-immobilization rate in soil could reach 56.10 %. Although all treatments 
      contribute to soil pH, fertility, and enzyme activities improvement, oyster shell 
      wastes (OS) had a better effect on soil cation exchange capacity. All treatments 
      had negative effects on soil respiration and bacterial community, but OS can 
      alleviate such adverse influence. Our results emphasized that Cd-resistant 
      ureolytic bacteria strain CJW-1 combined with OS had excellent ability and reuse 
      value to remediate Cd-contaminated environment.
