“…The authors further demonstrated that the use of native bacteria at low flow rates results in even delivery of calcite precipitation points at or lower than 4% by weight of the soil sample. In summary [111], it is suggested that the bacterial cell density and urea and calcium ion concentrations are important factors for effective calcite precipitation via MICP processes.…”

Until recently, engineers either ignored or neglected the role of microorganisms in geotechnical engineering. The microbially induced calcite precipitation (MICP) research technique is an innovative and relatively green technology which consists in a biological process through which microorganisms react with minerals (calcium source and cementation reagent) to produce calcite (CaCO 3 ) as a byproduct that modifies and improves the engineering properties of soil. Laboratory and field results obtained from various studies are promising and viable, suggesting potential for various engineering applications. This research technique has also been considered to be useful in many engineering applications such as improvement of construction materials, cementation of porous media, improvement in strength and stiffness of engineering soils, hydraulic control of engineering facilities (waste containment), liquefaction, and erosion mitigation. In this review, the various methods of production of calcium carbonates (calcite), the role played by bacteria, various state-of-the-art procedures that have evolved in this research area, as well as ongoing studies are reported. Furthermore, the use of the MICP technique in remediation of contaminants and other environmental concerns is also presented. The advantages and challenges (in form of undesired byproducts) of this research technique are highlighted herein.

“…Sustainable precipitation of carbonate minerals may provide green means of mitigating some geotechnical challenges associated with soils. Microbial-induced carbonate precipitation (MICP) and CO 2 -induced carbonate precipitation (CICP) can induce interparticle cementation and mineral precipitation in soil pore space to address geotechnical problems such as soil erosion and slope instability (Keykha et al 2017, Keykha et al 2018a, Romiani et al 2021.…”

The structure and shape of carbonate crystals formed by microbial activity and carbon dioxide reaction were investigated in this work. The mineral carbonates treated sandy soil was subsequently determined using unconfined compression tests (UCS). Sporoscarcina pasteurii bacteria were used to produce an aqueous solution of free carbonate ions (CO32-) under laboratory circumstances called microbial-induced carbonate precipitation (MICP). In CO2- induced carbonate precipitation, carbon dioxide was added to a sodium hydroxide solution to form free carbonate ions (CO32-) (CICP). Different carbonate mineral compositions were then provided by adding Fe2+, Mg2+, and Ca2+ ions to carbonate ions (CO32-). In the MICP and CICP procedures, the results of scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) revealed a distinct morphology of carbonate minerals. Vaterite (CaCO3), siderite (FeCO3), magnesium carbonate hydrate, or Nesquehonite (MgCO3 (H2O) 3) and dolomite (CaMg(CO3)2) were produced in MICP. Calcite (CaCO3), siderite (FeCO3), magnesium carbonate hydrate or Nesquehonite (MgCO3 (H2O) 3), and high-Mg calcite (CaMg(CO3)2) were produced in CICP. The results of UCS showed that siderite and high-Mg calcite /dolomite had more efficiency in soil strength. The lowest value of strength was related to magnesium carbonate hydrate treated soils. Mineral-treated soils in CICP showed a slightly higher UCS strength than MICP, which could be attributable to greater crystal particle sizes and particle interlocking.

“…e deposition of CaCO 3 increases as the concentration of cementation solution increases, but there are differences in the optimal cementation schemes, such as [41,48,50] (Figure 4). According to the research results of [49,51], the maximum deposition of CaCO 3 occurs in cement solutions with high Ca 2+ concentration. erefore, the cementation solution significantly influences the bacterial activity, CaCO 3 precipitation, and soil cementation in MICP (Table 1).…”

Microbially induced calcium carbonate precipitation (MICP) uses the metabolic function of microbes to carry out biochemical reactions with other substances in the environment. Through the controlled growth of inorganic minerals, soil particles are cemented and soil pores are filled to solidify the soil and reduce its permeability. Thus, the application of this technology was foreseen in geotechnical engineering and environment (building antiseepage, contaminated soil restoration, slope soil erosion, and sand liquefaction). In this review article, based on current research findings, the urea hydrolysis and the cementation mechanism of MICP are briefly described. The influences of factors such as enzyme activity, cementation solution concentration, pH, temperature, grouting method, and particle size on MICP-treated soil are discussed. The engineering properties of MICP-treated soils are evaluated, for instance, the strength, stiffness, liquefaction resistance, permeability, and durability. The applications of MICP technology in ground improvement, geotechnical seepage control, foundation erosion resistance, and fixation of heavy metals are summarized. Finally, future directions of the development of MICP technology are elucidated to provide a reference and guidance for the promotion of MICP technology in the geotechnical engineering field.
