      Bacteria in MICP Process.

AB  - The estimation of optical density (OD) with viable cells is challenging for 
      engineering purposes. In this study, the OD conversion based on previous study 
      was used. The inhibited and retarded behavior of the microbially induced 
      carbonate precipitation (MICP) process was examined. The experimental results 
      showed that high Ca(2+) drastically influences the inhibited and retarded 
      behavior on MICP processes. The analysis showed that the inhibition and 
      retardation effects occurred when the Ca(2+)/OD loading rate exceeded 8.46 M. The 
      critical value was equal to the proportional constant for obtaining carbonate 
      precipitation rate (CPR) from OD. Due to this, the blending design of materials 
      became possible, with no risk of inhibition. In conclusion, the inhibition and 
      retardation of the MICP process are governed by the Ca(2+) load and the linear 
      standard line (LSL), which may be attributed to the capacity or tolerance of 
      viable cells, i.e., CPR/OD = 8.46 M or Ca(2+)/OD = 8.46 M.
