“…Naturally, diatoms and green algae convert light energy into chemical energy via photosynthesis. Hence, the calcium carbonate in the interstices is precipitated as a by-product of photosynthesis [3,[9][10][11][12]. The ESI-MS signals of the demineralized samples included those of phenylalanine, an essential amino acid, and the existence of phenylamine becomes a strong biosignature (Figure 9).…”

“…For example, studies have focused on developing ecological techniques for repairing limestone using biomineralization [7][8][9]. Calcium carbonate can be used as a repairing material by biomediated precipitation as a by-product of microbial metabolic reactions such as photosynthesis [3,[9][10][11][12] and urea decomposition [3,9,[13][14][15][16][17][18][19][20][21][22][23][24]. In these biomediated environments, the cell wall and extracellular polymeric substances of the microorganism act as centers for carbonate precipitation [1,3,25].…”

“…In these biomediated environments, the cell wall and extracellular polymeric substances of the microorganism act as centers for carbonate precipitation [1,3,25]. This means that having activated microorganisms in the cracks and discontinuities of cracks facilitates the precipitation of biomediated calcium carbonate, which also acts as an adhesive material and increases rock strength and stability [9,11,12,26].…”

Microbially induced carbonate precipitation (MICP) has attracted worldwide attention as an environmentally friendly ground restoration technology in response to geohazards. This study describes the relationship between calcium carbonate growth within stalactite-type minerals formed around fractures in tuff breccia and microorganisms. Scanning electron microscopy revealed that calcium carbonate was precipitated in the interstices of rings formed in stalactite-type minerals, as if the carbonate minerals enhanced the strength of the silicate minerals. In addition, X-ray powder diffraction analysis detected that the calcium carbonates were calcite and vaterite. Moreover, microorganisms, such as diatoms and green algae, inhabited the interstices and, consequently, MICP by these microorganisms could play a role in the stability of outcrops. The stable isotope ratios of δ13C and δ15N and the mass spectral signals of the demineralized samples also encouraged diatoms and green algae to be involved in the formation of minerals.

“…Amongst lots of biogeotechnical engineering technologies, microbial-induced carbonate precipitation (MICP) acts as an innovative sustainable biomineralization technology (Fig. 1 ) and attracts wide attentions due to its feasibility and convenience in various fields (Chu et al 2011 ; Liu et al 2021a , b ; Martinez et al 2021 ; Zeng et al 2021 ), including geotechnical engineering, hydraulic engineering, geological engineering, ocean engineering, and environmental engineering (Terzis and Laloui 2019 ; Cheng et al 2021 ; Matsubara 2021 ; Sharma et al 2021 ). The MICP technology makes use of specific strains of bacteria which widely exist in nature and can deposit calcium carbonate through metabolic activities (Ramakrishnan et al 2001 ; Dhami et al 2013 ; Salifu et al 2016 ; Gardoso et al 2020 ).…”

Microbial‑induced carbonate precipitation (MICP) technology: a review on the fundamentals and engineering applications

et al. 2023

View full text Add to dashboard Cite

The microbial‑induced carbonate precipitation (MICP), as an emerging biomineralization technology mediated by specific bacteria, has been a popular research focus for scientists and engineers through the previous two decades as an interdisciplinary approach. It provides cutting-edge solutions for various engineering problems emerging in the context of frequent and intense human activities. This paper is aimed at reviewing the fundaments and engineering applications of the MICP technology through existing studies, covering realistic need in geotechnical engineering, construction materials, hydraulic engineering, geological engineering, and environmental engineering. It adds a new perspective on the feasibility and difficulty for field practice. Analysis and discussion within different parts are generally carried out based on specific considerations in each field. MICP may bring comprehensive improvement of static and dynamic characteristics of geomaterials, thus enhancing their bearing capacity and resisting liquefication. It helps produce eco-friendly and durable building materials. MICP is a promising and cost-efficient technology in preserving water resources and subsurface fluid leakage. Piping, internal erosion and surface erosion could also be addressed by this technology. MICP has been proved suitable for stabilizing soils and shows promise in dealing with problematic soils like bentonite and expansive soils. It is also envisaged that this technology may be used to mitigate against impacts of geological hazards such as liquefaction associated with earthquakes. Moreover, global environment issues including fugitive dust, contaminated soil and climate change problems are assumed to be palliated or even removed via the positive effects of this technology. Bioaugmentation, biostimulation, and enzymatic approach are three feasible paths for MICP. Decision makers should choose a compatible, efficient and economical way among them and develop an on-site solution based on engineering conditions. To further decrease the cost and energy consumption of the MICP technology, it is reasonable to make full use of industrial by-products or wastes and non-sterilized media. The prospective direction of this technology is to make construction more intelligent without human intervention, such as autogenous healing. To reach this destination, MICP could be coupled with other techniques like encapsulation and ductile fibers. MICP is undoubtfully a mainstream engineering technology for the future, while ecological balance, environmental impact and industrial applicability should still be cautiously treated in its real practice.

“…Another biological method used is stimulating microbes to generate biopolymer (microbial biopolymer accumulation) within the soil matrix, to improve the soil against erosion and permeability reduction [32][33][34]. Biofilm formation has a beneficial effect on soil stability and the reduction of soil hydraulic conductivity [26,[35][36][37][38][39]. Biogas generation, such as nitrogen, is also a biological method by which the liquefaction potential of sand is decreased.…”

Biopolymers as Green Binders for Soil Improvement in Geotechnical Applications: A Review

et al. 2021

View full text Add to dashboard Cite

Soil improvement using biopolymers has attracted considerable attention in recent years, with the aim to reduce the harmful environmental effects of traditional materials, such as cement. This paper aims to provide a review on the environmental assessment of using biopolymers as binders in soil improvement, biopolymer-treated soil characteristics, as well as the most important factors affecting the behavior of the treated soil. In more detail, environmental benefits and concerns about the use of biopolymers in soil improvement as well as biopolymer–soil interaction are discussed. Various geotechnical properties are evaluated and compared, including the unconfined compressive strength, shear strength, erosion resistance, physical properties, and durability of biopolymer-treated soils. The influential factors and soil and environmental conditions affecting various geotechnical characteristics of biopolymer-treated soils are also discussed. These factors include biopolymer concentration in the biopolymer–soil mixture, moisture condition, temperature, and dehydration time. Potential opportunities for biopolymers in geotechnical engineering and the challenges are also presented.
