“…Notably, the non-spore-forming Gram-positive bacterium Staphylococcus pasteurii was also isolated and tested in biomineralization investigations. Compared with S. pasteurii cells, the survival time of Staphylococcus pasteurii in the soil was much shorter due to the absence of spore formation [59].…”

Biomineralization has emerged as a novel and eco-friendly technology for artificial mineral formation utilizing the metabolism of organisms. Due to its highly efficient urea degradation ability, Sporosarcina pasteurii(S. pasteurii) is arguably the most widely investigated organism in ureolytic biomineralization studies, with wide potential application in construction and environmental protection. In emerging, large-scale commercial engineering applications, attention was also paid to practical challenges and issues. In this review, we summarize the features of S. pasteurii cells contributing to the biomineralization reaction, aiming to reveal the mechanism of artificial mineral formation catalyzed by bacterial cells. Progress in the application of this technology in construction and environmental protection is discussed separately. Furthermore, the urgent challenges and issues in large-scale application are also discussed, along with potential solutions. We aim to offer new ideas to researchers working on the mechanisms, applications and challenges of biomineralization.

“…Bio‐cementation—the enhancement of strength of soil through the activity of microorganisms or their by‐products—is a relatively new area of research where soil inoculants may play a role in reduction of environmental impacts through soil improvement. Microbially induced carbonate precipitation is mediated by urease‐producing microorganisms such as Sporosarcina pasteurii , which has been shown to improve the geotechnical properties of sand (Badiee et al, 2019). The studies referenced above hint at the potential for soil inoculants to be used to improve soil characteristics, but much more proof is needed in this area.…”

The burgeoning global market for soil microbial inoculants for use in agriculture is being driven by pressure to increase sustainable crop production by managing pests and diseases without environmental impacts. Microbial inoculants, based predominantly on bacteria and fungi, are applied to soil as alternatives to conventional inorganic fertilizers (biofertilizers) or to carry out specific functions including biocontrol of pests and diseases (biopesticides), or for bioremediation and enhancement of soil characteristics. While some soil inoculants such as rhizobia How to cite this article: O'

“…2), and the precipitated carbonates coat the soil grains, bind the particles effectively at particle contacts, eventually resulting the increase in strength of the soil (DeJong et al 2010;Achal and Kawasaki 2016;Omoregie et al 2020). Many investigations demonstrated that the MICP can be effectively implemented to various geotechnical applications including ground improvement (van Paassen et al 2010;Kalantary and Kahani 2019;Badiee et al 2019), liquefaction resistance in loose sands (Montoya et al 2013;Moosazadeh et al 2019), erosion control (Maleki et al 2016;Wang et al 2018;Jiang et al 2019), coastal protection (Nayanthara et al 2019;Imran et al 2019) and stabilizing dust and loess (Meyer et al 2011;Sun et al 2020).…”

Cyclic wet-dry is one of the influential weathering agents which can rapidly alter the mechanical properties of soils, limiting their durability and consistent performance. This study investigates the effect of wet-dry cycles on the mechanical behaviour of bio-cemented soil. Microbial-induced carbonate precipitation-based bio-cementation is an innovative soil improvement method, which is gaining increasing attention as a potential alternative for stabilizing slope surface. As the treated surfaces are exposed to repeated rainfalls and draughts, durability analysis is essential; cyclic wet-dry tests were therefore performed as a credible indicator of durability. The soil obtained from the Hokkaido expressway slope was treated at laboratory to varying cementation levels (% CaCO3) and subjected to 50 subsequent wet-dry cycles. Physical and mechanical changes were monitored using mass loss, shear wave velocities and needle penetration tests during wet-dry cycles. The results showed that the wet-dry cycles deteriorated the physical and mechanical at two stages. The mass and S-wave velocity of specimens significantly dropped after first few cycles and then tended to reach equilibrium. The second stage of notable deterioration was observed between 30 and 50 wet-dry cycles. It is suggested that the erosion of weak and powdery deposition of CaCO3 causes the degradation at the early stage, whereas the degradation in the late stage was attributed to the microstructural deformations of intact carbonate bonds. It was also found that the increase in cementation level decreases the deterioration of bio-cemented soil under wet-dry cycles.
