“…Bio‐augmentation is an approach where the exogenous bacteria cultured in the laboratory are added into the soil (Jain & Arnepalli, 2019; Mujah et al, 2019; Xiao et al, 2019a). In contrast, the bio‐stimulation approach modifies the local environment by injecting nutrient media to enrich indigenous ureolytic bacteria capable of continuously producing a large quantity of urease to generate bio‐cementation.…”

For a long time in the practice of geotechnical engineering, soil has been viewed as an inert material, comprising only inorganic phases. However, microorganisms including bacteria, archaea and eukaryotes are ubiquitous in soil and have the capacity and capability to alter bio‐geochemical processes in the local soil environment. The cumulative changes could consequently modify the physical, mechanical, conductive and chemical properties of the bulk soil matrix. In recent years, the topic of bio‐mediated geotechnics has gained momentum in the scientific literature. It involves the manipulation of various bio‐geochemical soil processes to improve soil engineering performance. In particular, the process of microbial‐induced calcium carbonate precipitation (MICP) has received the most attention for its superior performance for soil improvement. The present work aims to shape a comprehensive understanding of recent developments in bio‐mediated geotechnics, with a focus on MICP. Referring to around one hundred studies published over the past five years, this review focuses on popular and alternative MICP processes, innovative raw materials and additives for MICP, emerging tools and testing methodologies for characterizing MICP at multi‐scale, and applications in emerging and/or unconventional geotechnical fields.

“…Employing the augmentation process is not viable compared to stimulation because of high cost, disturbance to the surrounding, adverse effect of the environment on ureolytic microbes and vice versa. The major problem associated with MICP via ureolysis is the hindrance of microbial activity in low or the absence of oxygen due to the aerobic nature of ureolytic microbes [ 1 19–20 ]. Hence, the ureolytic activity and mineral precipitation get hindered in most of the MICP application processes such as in oil reservoirs, healing the concrete crack, subsurface soil reinforcement, soil remediation below ground water, etc.…”

“…It concludes that the ureolysis process not only remediates the polluted soil but also displaces it with another contaminant, i.e., ammonia, which has adverse environmental effects [ 133 ]. Also, the aerobic nature of ureolytic bacteria hinders the microbial and biomineralization activity on the subsurface i.e., low or no oxygen conditions [ 19 ].…”

The naturally occurring biomineralization or microbially induced calcium carbonate (MICP) precipitation is gaining huge attention due to its widespread application in various fields of engineering. Microbial denitrification is one of the feasible metabolic pathways, in which the denitrifying microbes lead to precipitation of carbonate biomineral by their basic enzymatic and metabolic activities. This review article explains all the metabolic pathways and their mechanism involved in the MICP process in detail along with the benefits of using denitrification over other pathways during MICP implementation. The potential application of denitrification in building materials pertaining to soil reinforcement, bioconcrete, restoration of heritage structures and mitigating the soil pollution has been reviewed by addressing the finding and limitation of MICP treatment. This manuscript further sheds light on the challenges faced during upscaling, real field implementation and the need for future research in this path. The review concludes that although MICP via denitrification is an promising technique to employ it in building materials, a vast interdisciplinary research is still needed for the successful commercialization of this technique.

“…The field studies were also conducted because of widespread presence of ureolytic bacteria in the environment (Eryürük et al 2016 ; Cheng et al, 2017 ; Nayanthara et al 2019 ). Although there are a number of species which produce CaCO 3 minerals, Sporosarcina pasteurii was used by many researchers widely and there are numerous reports on bacterial CaCO 3 precipitation by this bacterium (Nemati et al 2003 ; Ivanov and Chu 2008 ; Tobler et al 2011 ; Al-Thawadi and Cord-Ruwisch 2012 ; Yasuhara et al 2012 ; Al Imran et al 2018 ; Seifian and Berenjian 2019 ; Ghosh et al 2019 ; Jain and Arnepalli 2019 ) because Sporosarcina pasteurii is a Biosafety Level (BSL) 1 bacterium with high urease activity (Eryürük et al 2015a ). The process is based on metabolic activity of the bacteria.…”

The effect of number of cells deposited on decrease in hydraulic conductivity of porous media using CaCO3 precipitation induced by Sporosarcina pasteurii (ATCC 11,859) was examined in columns packed with glass beads in the range of 0.25 mm and 3 mm in diameter. After resting Sporosarcina pasteurii cells were introduced into the columns, a precipitation solution, which consisted of 500 mM CaCl2 and 500 mM urea, was introduced under continuous flow conditions. It was shown that hydraulic conductivity was decreased by formation of microbially induced CaCO3 precipitation from between 8.37 * 10−1 and 6.73 * 10−2 cm/s to between 3.69 * 10−1 and 1.01 * 10−2 cm/s. The lowest hydraulic conductivity was achieved in porous medium consisting of the smallest glass beads (0.25 mm in diameter) using the highest density of cell suspension (OD600 2.25). The number of the deposited cells differed depending on the glass bead size of the columns. According to the experiments, 7 * 10−9 g CaCO3 was produced by a single resting cell. The urease activity, which led CaCO3 precipitation, depended on presence of high number of cells deposited in the column because the nutrients were not included in the precipitation solution and consequently, the amount of CaCO3 precipitated was proportional with the cell number in the column. A mathematical model was also developed to investigate the experimental results, and statistical analysis was also performed.
