Feasibility of microbially induced carbonate precipitation
01/06/2020· Bacteria not only provides ureases, they also provide nucleation sites for calcium carbonate formation. Microbial cell surfaces generally carry negative charges, which can adsorb positively charged ions onto the cell surface, therefore, the CO 3 2– transported from the inside the cell to its surface combines with the Ca 2+ in solution, resulting in calcium carbonate precipitation ( Fig. 3 b).
