Abstract ：
Microbial-induced carbonate precipitation (MICP) technique has the potential to be an eco-friendly and sustainable solution for engineering problems. Despite the extensive amount of research that has been conducted recently on the MICP technique, there are few studies on the constitutive model of MICP-treated specimens. In this study, the statistical damage constitutive model of MICP-treated specimens was established based on the statistical theory and damage mechanics theory. The proposed model assumed that the microelement strength of biocemented sand follows the lognormal distribution and the Drucker-Prager criterion. The parameters S0 and F0 in the constitutive model were determined, and their physical significance was then discussed. The reasonableness of the proposed model was verified by comparing the theoretical results and the experimental results. The evolution of the damage variable (D), parameter S0, and parameter F0 with different calcium carbonate content (CCC) was analyzed. The statistical damage model based on the lognormal distribution was then compared with that based on the Weibull distribution. The results show that the parameter F0 and S0 can reflect the limiting strength and brittleness of MICP-treated specimens.. The specimens with higher cementation tend to have a higher accelerated damage rate. The damage variables eventually reach a stable value as the axial deformation increases. The proposed model can reflect the strain softening and strain hardening phenomena well, which can also represent the shear expansion and shear contraction characteristics of the volume strain curve. Overall, the research in this study can provide some theoretical support for the engineering application of MICP-treated specimens.

Abstract ：
Enzyme-induced carbonate precipitation (EICP) has emerged as an innovative soil stabilization technology to precipitate CaCO3 by catalyzing urea decomposition. Although extensive efforts have been made to increase the calcium carbonate content (CCC) formed in the EICP process for the better bio-cementation effect, the cementability and micromechanical properties of CaCO3 are rarely known. A study of the cementitious characteristics and micromechanical properties of CaCO3 precipitates with different mixing percentages of crystal morphology is essential for soil improvement. In the present study, ultrasonic oscillation tests and nanoindentation tests were performed to investigate the cementability and micromechanical properties of CaCO3 precipitate. The results show that the cementability and micromechanical properties of CaCO3 precipitate are related to the composition of the crystal morphology. A high content of calcite is beneficial to improve the adhesion of calcium carbonate precipitate. Calcite has better mechanical properties (elastic modulus, hardness and ductility) than vaterite, and the presence of vaterite can significantly affect the measured value of mechanical properties in nanoindentation tests. The ductility of CaCO3 precipitate induced by crude soybean urease (CSU) is higher than that of CaCO3 precipitate induced by commercially available pure enzyme, suggesting that commercially available pure enzyme can be replaced by CSU for cost-effective field-scale engineering applications. This work can provide insight into optimizing the properties of CaCO3 precipitate from the micro-scale. © 2024 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences

Abstract ：
The thermal conductivity of backfill materials directly affects the heat transfer efficiency between energy geo-structures and the surrounding stratum. Microbially induced carbonate precipitation (MICP) possesses great potential for improving the thermal conductivity of backfill materials. Magnetic iron oxide nanoparticles (i.e., nano-Fe3O4) have been proven to enhance bacterial biochemical activity by altering the permeability of bacterial biofilms, thus potentially improving the MICP process. It was supposed to enhance the thermal conductivity of backfill materials, allowing for applying energy geo-structures in arid environments. In this study, MICP in a solution environment was conducted to analyze bacterial urease activity and morphology of precipitation at varying nano-Fe3O4 contents. Additionally, sand columns treated with MICP and different nano-Fe3O4 contents were performed to obtain the thermal conductivity and unconfined compressive strength (UCS) through the transient plane source (TPS) method and uniaxial compression (UC) experiment. The mineral type, precipitation morphology, and microstructure were identified using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The mechanism of the effect of nano-Fe3O4 on bacterial urease activity and thermal-mechanical behaviors was also discussed. The results indicated that the nano-Fe3O4 could enhance bacterial urease activity and promote vaterite precipitation in the solution environment. Conversely, when applied to MICP-treated sand, nano-Fe3O4 could facilitate calcite formation. Increasing the nano-Fe3O4 content showed a positive correlation with increased thermal conductivity and UCS. Specifically, the optimal values of thermal conductivity and UCS increased by 2.42 times and 2.39 times, respectively, compared to MICP-treated specimens without nano-Fe3O4. Microstructure analysis revealed that calcite precipitation at the particle contact served a dual function: cementing particles, thereby improving the mechanical strength and simultaneously acting as a “thermal bridge” to enhance the thermal conductivity. Furthermore, this study provides a new perspective on utilizing magnetized bacteria to reinforce specific locations within rocks and soils in the presence of an external magnetic field. © 2024 Elsevier Ltd

Abstract ：
Bio-cementation technology based on crude soybean urease is a new environmentally friendly foundation treatment technology emerging in the field of geotechnical engineering. The uniformity of bio-cementation is a pressing issue that needs to be addressed to advance the application of this technology in practical engineering, and soil particle size stands as a significant influencing factor. In this study, 13 types of sand with varying particle sizes were selected, along with self-extracted crude soybean urease solution, to conduct urease percolation tests, sand column curing tests, and scanning electron microscope (SEM) examinations. These experiments aimed to analyze the influence of soil particle size on the effectiveness of bio-cementation using crude soybean urease and explore its underlying mechanisms. The findings reveal that soil particle size significantly affects the migration and adsorption of urease in the crude soybean urease solution. Smaller soil particle sizes facilitate the adsorption of urease. However, excessively small particle sizes (e.g., less than 0.425 mm) lead to the concentration of most adsorbed urease in the middle and upper regions of the soil column. Conversely, excessively large particle sizes (e.g., greater than 4.750 mm) hinder urease adsorption in these regions. Both scenarios tend to result in uneven bio-cementation. Besides the amount of urease adsorption, the influence of soil particle size effect on the biocementation efficacy based on soybean urease is also associated with factors such as pore size within the soil and the number of particle contacts per unit volume of soil. Larger soil particles result in larger interstitial pore sizes and fewer particle contacts, thus hindering the formation of effective calcium carbonate crystals. © 2024 Biodiversity Research Center Academia Sinica.

Abstract ：
The one-phase-low-pH method is a simple,efficient,and user-friendly biogrouting technique that can effectively improve the biomineralization of enzyme-induced carbonate precipitation(EICP)using free urease enzyme.One of the most significant advantages of this method is its capacity to effectively delay calcium carbonate(CaCO3)precipitation by reducing the pH of the solution through the addition of acid.This prevents bioclogging during the biogrouting process and improves the biomineralization effect.However,the biomineralization of the one-phase-low-pH based EICP method may be influenced by the specific acid used.To investigate the impact of acid type on the one-phase-low-pH EICP method using crude soybean urease solution(CSUS),four types of acids,including hydrochloric acid(HCl),nitric acid(HNO3),acetic acid(CH3COOH),and lactic acid(C3H6O3),were used to adjust the pH of CSUS.A series of macroscopic and microscopic experiments were conducted to evaluate the effect of acid type on the one-phase-low-pH EICP method.The results indicate that the acid has an inhibition on the urease activity(UA)of CSUS.Among the acids tested,HNO3 exhibits the most pronounced inhibitory effect on the UA of CSUS,followed by HCl,and the least pronounced inhibitory effect for CH3COOH and C3H6O3 under the same pH conditions.Meanwhile,CH3COOH and C3H6O3 could provide a longer delay duration of CaCO3 precipitation than HNO3 and HCl.Therefore,the one-phase-low-pH EICP method based on CH3COOH and C3H6O3 can significantly improve the effective biocementation depth compared to that based on HNO3 and HCl.Nevertheless,the different types of acids appear to have no obvious effect on the polymorph and crystalline of the precipitated CaCO3 crystals.

Abstract ：
Bacterial suspension is an essential component of microbially induced carbonate precipitation(MICP)-based biocement and a large-scale production is required for field applications.In this study,a new bacterial concentration method is proposed to enable high concentration bacterial suspension to be produced to facilitate field work.By adding low concentration calcium to bacterial suspension,flocs are formed and bacterial cells are adsorbed on the flocs to achieve bacterial concentration.Compared to the traditional bacterial concentration method using centrifugation and freezing-drying method,the pro-posed method can concentrate a large volume of bacterial suspension without using special equipment.The feasibility of this method is verified by bacterial concentration tests,solution tests and sand column treatment tests.The results of both the solution test and the sand column treatment test show that the bacterial suspension concentrated by the proposed method can be effectively used for soil bio-cementation.There is a threshold calcium concentration that allows a complete bacterial concentration for the proposed method,and this threshold calcium concentration tends to increase linearly with the optical density of the cell suspension at a wavelength of 600 nm(OD600).

Abstract ：
Calcium salt is an important contributing factor for calcium-based biomineralization. To study the effect of calcium salt on soil biomineralization using crude soybean urease, the calcium salts, including the calcium chloride (CaCl2), calcium acetate ((CH3COO)(2)Ca) and calcium nitrate (Ca(NO3)(2)), were used to prepare the biotreatment solution to carry out the biomineralization tests in this paper. Two series of biomineralization tests in solution and sand column, respectively, were conducted. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed to determine the microscopic characteristics of the precipitated calcium carbonate (CaCO3) crystals. The experimental results indicate that the biomineralization effect is the best for the CaCl2 case, followed by (CH3COO)(2)Ca, and worst for Ca(NO3)(2) under the test conditions of this study (i.e. 1 mol/L of calcium salt-urea). The mechanism for the effect of the calcium salt on the biomineralization of crude soybean urease mainly involves: (1) inhibition of urease activity, and (2) influence on the crystal size and morphology of CaCO3. Besides Ca2+, the anions in solution can inhibit the activity of crude soybean urease, and NO3- has a stronger inhibitory effect on the urease activity compared with both CH3COO- and Cl-. The co-inhibition of C-a2+ and NO3- on the activity of urease is the key reason for the worst biomineralization of the Ca(NO3)(2) case in this study. The difference in biomineralization between the CaCl2 and (CH3COO)2(C)a cases is strongly correlated with the crystal morphology of the precipitated CaCO3.
