AB  - The microbiologically induced calcite precipitation (MICP) has been extensively 
      studied for geotechnical engineering through simultaneous action of natural 
      phenomena and engineering processes. The focus of bacterial contribution to the 
      MICP has been directed to calcium carbonate productivity, while the additional 
      bacterial role as a crystal nucleation center was not explained especially from a 
      mathematical prediction modeling point of view. Therefore, this study provides 
      explanations and a mathematical modeling approach of bacterial influence on the 
      MICP induced by newly-isolated ureolytic Bacillus strains and Sporosarcina 
      pasteurii DSM 33. Using the obtained results of low-cost, rapid, and simple 
      assays, artificial neural network modeling was applied for cell surface 
      predispositions, pH changes as well as calcium-involved function in biofilm 
      formation during the MICP, for the first time. Based on the obtained contribution 
      of the alkalophilic/alkaloresistant bacteria, calcite precipitation can be 
      significantly directed by the presence, of ureolytic bacterial cells as 
      nucleation centers during CaCO(3) precipitation as well as their morphology, 
      surface characteristics, potential to form a biofilm, and/or generate pH changes.
