“…Liu et al [56] assessed the interaction between S. pasteurii and an indigenous bacterium during MICP soil treatment. In their study, two soil samples, i.e., natural soil extract (with indigenous bacteria present) and artificial soil extract (with no microorganisms) were treated with an MICP treatment solution containing S. pasteurii.…”

Microbial-induced calcite precipitation (MICP) is a promising new technology in the area of Civil Engineering with potential to become a cost-effective, environmentally friendly and sustainable solution to many problems such as ground improvement, liquefaction remediation, enhancing properties of concrete and so forth. This paper reviews the research and developments over the past 25 years since the first reported application of MICP in 1995. Historical developments in the area, the biological processes involved, the behaviour of improved soils, developments in modelling the behaviour of treated soil and the challenges associated are discussed with a focus on the geotechnical aspects of the problem. The paper also presents an assessment of cost and environmental benefits tied with three application scenarios in pavement construction. It is understood for some applications that at this stage, MICP may not be a cost-effective or even environmentally friendly solution; however, following the latest developments, MICP has the potential to become one.

“…3.1 Effect of soil properties I) Soil Type: To date, MICP treatment has been widely applied for different types of soils, including clay [52,53,[148][149][150], silt [150,151], residual soil [42,129,[152][153][154][155], coal ash [156,157], expansive soil [158], tabia [159], mixture of sand and clay [63,121,[160][161][162] or silt [163][164][165], sandy soil [166,167], fine sand [85,168], coarse sand [85,[168][169][170][171][172][173], calcareous sand [56,118,137,[174][175][176][177][178], gravel [150,179,180] and aggregate [116,[1...…”

“…For instance, Rebata-Landa [150] found that the clay was uncemented due to the ignorable calcite content after 32 d of treatment. Kannan et al [53] also reported that biostimulation is not effective in marine clay. Moreover, Sasaki and Kuwano [161] found that the improvement in liquefaction resistance was ignorable for the sand-clay mixture with MICP treatment and attributed it to the much small void ratio of the mixture causing the clogging of bacteria near the injection areas.…”

“…Some other microorganisms, such as Myxococcus xanthus [27], Thraustochytrium striatum [28], Escherichia coli HB101 [29], Bacillus sphaericus [30], and Sarcina ureae [31], also have been applied for the MICP treatment. The UPB also can be enriched or isolated from the local soil [25,[32][33][34][35][36][37][38][39][40][41][42][43], groundwater [44] or waste-activated sludge [45,46], or in situ stimulated the natural indigenous bacteria [47][48][49][50][51][52][53][54][55][56].…”

Microbial geotechnology or biogeotechnology is a new branch of geotechnical engineering. It involves the use of microbiology for traditional geotechnical applications. Many new innovative soil improvement methods have been developed in recent years based on this approach. A proper understanding of the various approaches and the performances of different methods can help researchers and engineers to develop the most appropriate geotechnical solutions. At present, most of the methods can be categorized into three major types, biocementation, bioclogging, and biogas desaturation. Similarities and differences of different approaches and their potential applications are reviewed. Factors affecting the different processes are also discussed. Examples of up-scaled model tests and pilot trials are presented to show the emerging applications. The challenges and problems of biogeotechnology are also discussed.

“…MICP can lead to biocementation which is the generation of bonds (cements) between soil particles caused by Ca 2+ -based mineral polymorphs [27][28][29]. Such bonds act as bridges between particles resulting in an increase in the shear strength [30][31][32][33][34] and a reduction of the void space between particles (and therefore a reduction in the material permeability) [2,35,36]. Numerous studies shown above have indicated the potential and possibility of using MICP to improve the sand strength with a minor problem being the movement of treatment depth since treating potential wastelands with larger depth might be a constraint [37].…”

Microbially induced calcite precipitation performance of multiple landfill indigenous bacteria compared to a commercially available bacteria in porous media

et al. 2021

Microbially Induced Carbonate Precipitation (MICP) is currently viewed as one of the potential prominent processes for field applications towards the prevention of soil erosion, healing cracks in bricks, and groundwater contamination. Typically, the bacteria involved in MICP manipulate their environment leading to calcite precipitation with an enzyme such as urease, causing calcite crystals to form on the surface of grains forming cementation bonds between particles that help in reducing soil permeability and increase overall compressive strength. In this paper, the main focus is to study the MICP performance of three indigenous landfill bacteria against a well-known commercially bought MICP bacteria (Bacillus megaterium) using sand columns. In order to check the viability of the method for potential field conditions, the tests were carried out at slightly less favourable environmental conditions, i.e., at temperatures between 15-17°C and without the addition of urease enzymes. Furthermore, the sand was loose without any compaction to imitate real ground conditions. The results showed that the indigenous bacteria yielded similar permeability reduction (4.79 E-05 to 5.65 E-05) and calcium carbonate formation (14.4–14.7%) to the control bacteria (Bacillus megaterium), which had permeability reduction of 4.56 E-5 and CaCO3 of 13.6%. Also, reasonably good unconfined compressive strengths (160–258 kPa) were noted for the indigenous bacteria samples (160 kPa). SEM and XRD showed the variation of biocrystals formation mainly detected as Calcite and Vaterite. Overall, all of the indigenous bacteria performed slightly better than the control bacteria in strength, permeability, and CaCO3 precipitation. In retrospect, this study provides clear evidence that the indigenous bacteria in such environments can provide similar calcite precipitation potential as well-documented bacteria from cell culture banks. Hence, the idea of MICP field application through biostimulation of indigenous bacteria rather than bioaugmentation can become a reality in the near future.
