Therefore, bound ions (metal ions) react with anions (carbonates) to form insoluble calcium carbonate (De Muynck et al., 2010b). Bacterial cells play a key role in the MICP because, in addition to being used as nucleation sites, they affect the type of mineral that is going to be formed ( Douglas & Beveridge, 1998 ; Rodriguez-Navarro, Jroundi, Schiro, Ruiz-Agudo & Gonzalez-Muñoz, 2012 ).
