AB  - Microbially induced calcium carbonate precipitation (MICP) is ubiquitous in the 
      earth's lithosphere and brings the inspiration of bionic cementation technology. 
      Over recent years, MICP has been proposed as a potential solution to address many 
      environmental and engineering issues. However, the stability of cemented 
      precipitations generated via MICP technology, especially the characteristics and 
      change mechanism of crystal forms, is still unclear, which substantially hindered 
      the understanding of biomineralization and prohibited the application and 
      upscaling of MICP technology. Here, Sporosarcina pasteurii was selected as a 
      model microbe to induce calcium carbonate mineralization in a series of standard 
      nutrient solutions. The authors studied the process of precipitation from 
      amorphous calcium carbonate to calcite crystal form and revealed the assembly 
      behavior and mechanism of precipitations by FTIR, SEM, TEM and EDS. In the two 
      crystal forms of induced calcium carbonate, the relative position and content of 
      C, O, N, P and Ca elements were only slightly different. The molecular attachment 
      and structural match of organic matrix made the crystals form change. Finally, a 
      self-assembly theory was proposed to MICP, and it provided a solid theoretical 
      basis for the technical specification of MICP technology in engineering 
      application. KEY POINTS: * Organic matrix is intensively involved in MICP by 
      forming functional groups. * Molecular attachment and structural match cause 
      calcite crystal evolution. * A self-assembly theory is proposed for MICP.
