Formations of calcium carbonate minerals by bacteria and its multiple applications (2016, background): “Microbial cell surfaces have negatively charged and act as scavengers for cations, particularly Ca2+, in aquatic environments by binding them onto their cell surfaces; accordingly, microorganisms act as ideal crystal nucleation sites (Stocks-Fischer et al. 1999; Ramachandran et al. 2001).”
Biogrout, ground improvement by microbial induced carbonate precipitation (2009, background): “, 2003), strengthening of concrete (Ramachandran et al., 2001) and selective plugging for enhanced oil recovery (Ferris & Setehmeir, 1992; Gollapudi et al.”
Effect of particle size distribution on the bio-cementation of coarse aggregates (2017, neutral): “1 [25, 26, 28] Concentration of cells permL 1⁄4 8:59 10(7) OD 600 ð1Þ”
Microbial Concrete: Way to Enhance the Durability of Building Structures (2011, background): “…in compressive strength by Bacillus sp. CT-5 is probably due to deposition of CaCO3 on the microorganism cell surfaces and within the pores of cement–sand matrix, which plug the pores within the mortar [Ramakrishnan et al. 1998; Ramachandran et al. 2001; Ghosh et al. 2005; Achal et al. 2009a].”
Biocalcification of Sand through Ureolysis (2011, background): “Growing cells increased the CBR, especially in the case of dense sand, presumably owing to microbially induced precipitate formation (Ramachandran et al. 2001; DeJong et al. 2006).”
A review of microbial precipitation for sustainable construction (2015, background): “Application of MICP has been demonstrated in the remediation of heavy metals [9,10,8], soil strengthening and improvement [112], restoration of stone materials [23,96,99,87], wastewater treatment [51], sand consolidation [2]), strengthening of concrete [83], and durability of building materials [32,”
