Influence of Culture Medium on Cementation of Coarse Grains Based on Microbially Induced Carbonate Precipitation

A main challenge in the large-scale application of microbially induced carbonate precipitation (MICP) technique includes low efficiency cementation coarse grains. Actually, MICP treatment process, effect bonding points was more important than pore filling due to large porosity for To achieve a better at between particles, quick formation and growth biofilm is necessary. In this study, an optimized medium proposed improve effects materials. The other different media were used bio-cementation tests with MICP. viable cell concentrations, strengths, microscopic characteristics, contents, calcium (CaCO3) contents evaluate its effects. tests, led increased CaCO3 compared media. Indeed, strength sample treated 1.2–4 times higher that values advantages demonstrated via tests.
