“…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.

This paper examines the bio-derived stabilization of sand-only or sand-plus-silt soils using an extracted bacterial enzyme application to achieve induced calcite precipitation (ICP). As compared to conventional microbial induced calcite precipitation (MICP) methods, which use intact bacterial cells, this strategy that uses free urease catalysts to secure bacterial enzyme–induced calcite precipitation (BEICP) appears to offer an improved means of bio-stabilizing silty-sand soils as compared to that of MICP processing. Several benefits may possibly be achieved with this BEICP approach, including bio-safety, environmental, and geotechnical improvements. Notably, the BEICP bio-stabilization results presented in this paper demonstrate (i) higher rates of catalytic urease activity, (ii) a wider range of application with sand-plus-silt soil applications bearing low-plasticity properties, and (iii) the ability to retain higher levels of soil permeability after BEICP processing. Comparative BEICP versus MICP results for sand-only systems are presented, along with BEICP-based results for stabilized soil mixtures at 90:10 and 80:20 percentile sand:silt ratios. This BEICP method’s ability to obtain unconfined compressive strength results in excess of 1000 kPa with sand-plus-silt soil mixtures is particularly noteworthy.

“…Crude extracts of jack bean (Canavalia ensiformis) also have the potential to be used instead of commercially available purified urease due to similar rates of calcite formation. 9) Furthermore, sword beans urease was also used to reduce the permeability by more than one order of magnitude and to increase unconfined compressive strength value up to 1620 kPa by producing CaCO 3 . 10) There are few laboratory scale studies on sand cementation technique via plant-derived urease related to geotechnical and rock engineering.…”

Sand Cementation Test using Plant-Derived Urease and Calcium Phosphate Compound

The investigation of urease containing plant species and the calcium phosphate compounds (CPCs) precipitation along with plant derived urease were performed at laboratory scale. At first, small scale laboratory samples (height, h = 10 cm & inner diameter, ¤ = 5 cm) were made using Toyoura sand and only from CPC solution having different Ca/P ratios to use as control samples. Afterward, another Toyoura sand test pieces were made by mixing watermelon seed extract, urea with different concentrations and CPC solution having different Ca/P ratios to study the optimal cementation. Test pieces were cured up to 28 days in an airtight container at high humidity at 25°C and carried out unconfined compressive strength (UCS) test. The UCS of the sand test pieces cemented by CPC with urease containing plant extract and urea were larger than that of the test pieces without plant extract. Furthermore, the best CPC solution mixture for highest cementation was with the concentration of Ca/P ratio of 0.5. In addition, pH content was measured after UCS test. Maintaining pH around 8 in the specimen at 28 days was significant to get optimal cementation.
