AB  - The urease-based microbially induced carbonate precipitation (MICP) is known as 
      effective remediation strategy in soil metals remediation; however, all related 
      studies confined to bioaugmentation. In the present study, biostimulation process 
      was adopted for the first time in accelerating MICP in copper (Cu) immobilization 
      in soil. The abundance, composition, and diversity of the bacterial community 
      after biostimulation were assessed with MiSeq Illumina sequencing analysis that 
      confirmed number and types of ureolytic and calcifying bacteria grown 
      significantly leading to MICP process, compared to untreated soil. The results 
      demonstrated that biostimulation induced calcite precipitation in soil that 
      immobilized Cu mainly in carbonated fraction of soil, while soluble-exchangeable 
      fraction decreased from 45.54 mg kg(-1) to 1.55 mg kg(-1) Cu in soil. Scanning 
      electron microscopy (SEM) cum energy-dispersive X-ray spectroscopy (EDX) 
      evaluated structure and elemental composition in Cu immobilization after 
      biostimulation. Fourier Transform-Infra Red (FTIR) spectroscopy depicted 
      functional chemical groups involved in copper immobilization, while X-Ray 
      Diffraction (XRD) identified main crystalline phases or biominerals formed during 
      biostimulation in order to carryout Cu remediation from soil.
