AB  - The bacterium Sporosarcina pasteurii can produce significant volumes of solid 
      precipitation in the presence of specific chemical environments. These solid 
      precipitate particles can enter a network of microscale pores and cause 
      long-range clogging. As a result, the medium gains strength and exhibits superior 
      mechanical properties. This concept is also known as Microbiologically Induced 
      Calcite Precipitation (MICP). In this study, we have used sponge blocks as 
      surrogate porous media mimics and analyzed several aspects of MICP. A synergistic 
      approach involving electron microscopy (SEM), computerized X-Ray tomography 
      (muCT), quasi-static compressive load testing and chemical characterization (EDX) 
      has been used to understand several physical and chemical aspects of MICP.
