Short summary

Microbially induced carbonate mineral precipitation (MICP) is a natural process that is also being investigated for subsurface engineering applications including radionuclide immobilization and microfracture plugging. We demonstrate that rates of MICP from microbial urea hydrolysis (ureolysis) vary with different bacterial strains, but rates are similar in both oxygenated and oxygen-free conditions. Ureolysis MICP is therefore a viable biotechnology in the predominately oxygen-free subsurface.
