“…Microbe‐induced calcite precipitation by urease‐producing bacteria is a potential solution to address these issues ( Figure A). [ 272 ] Urease catalyzes the hydrolysis of urea into ammonium and carbamate. Carbamate is spontaneously hydrolyzed to carbonic acid and ultimately to bicarbonate by carbonic anhydrase.…”

Bacteria play an important role in the calcification process of natural minerals and within organisms ( Table 1). It is Microbe-mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses, and algae. These mineralization processes comprise calcification, silicification, and iron mineralization. The mechanisms for mineral formation include extracellular and intracellular biomineralization. The mineral precipitating capability of microbes is often harnessed for green synthesis of metal nanoparticles, which are relatively less toxic compared with those synthesized through physical or chemical methods. Microbe-mediated mineralization has important applications ranging from pollutant removal and nonreactive carriers, to other industrial and biomedical applications. Herein, the different types of microbe-mediated biomineralization that occur in nature, their mechanisms, as well as their applications are elucidated to create a backdrop for future research.

“…Among these applications are amending or improving construction materials and remediation of cracks/self-healing in concrete [3, 72, 79-86, 102, 118-122], as well as cementation of porous media and improvements in strength and stiffness [6,7,26,35,103,117,121,123]. It is also used in environmental remediation of heavy metals and radionuclides, including the potential to reduce subsurface leakage in the background of geologically isolated carbon dioxide [72,104,105,[124][125][126][127][128][129][130][131][132][133][134][135]. Recent studies [136] have reported MICP as a conservative method for restoring the lost strength in decayed limestone through biomineralization processes, for trial tests in both laboratory and field conditions.…”

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.

Self‐Healing of Cracks in Concrete Using Bacillus Strains Encapsulated in Sodium Alginate Beads

et al. 2020

This research focused on the self‐healing of micro‐cracks in concrete by using different Bacillus strains. The encapsulation of strains in sodium alginate was protected with the bacterial mass, which prevented them from leaching. A viability test was performed to check the viability of bacteria in the highly alkaline environment. The encapsulated bacterial mix having 2–3% of total volume of concrete cubes was effective without compromising compressive strength. The calcium carbonate (CaCO3) precipitation was observed under urease activity. The SEM (Scanning Electron Microscope) revealed the direct involvement of ureolytic bacteria in CaCO3 precipitation. A 16% increase in compressive strength in concrete and significant healing was achieved with Bacillus Subtilis. However, with Bacillus Anthracis, only 6% increase in the concrete strength was achieved. Moreover, the Bacillus Pasteurii did not give effective results. Bacillus Subtilis provided better results than the other strains. The bacterial culture in sodium alginate beads within 2–3% was optimum for compressive strength and self‐healing of cracks.
