“…The presence of significant amounts of carbonate compounds (e.g., >3% w/w CaCO 3 ) in calcareous stones or lime mortars, results in the buffering of biogenic metabolic products producing a constant suitable pH-milieu for the growth of microorganisms [38]. Moreover, these microbes are also capable to precipitate CaCO 3 via hydrolysis of urea [39]. These species are responsible for the biologically induced corrosion of stone and other building materials in the archaeological sites.…”

This paper focuses on the role played by the clay minerals and microorganisms in the deterioration process of Coptic architecture units at the church of Virgin Mary, Wadi El-Natrun region. For this purpose building materials (mainly mortars and plasters) from the studied church were examined using X-ray diffraction (XRD), X-ray fluorescence (XRF) and scanning electron microscope with energy dispersive spectroscopy (SEM-EDS); in order to identify their composition and were investigated petro-graphically to determine the real response of the masonry structure to the deformation imposed at the endogenous factors. Wall gypsum mortars in the church contain halloysite as a dominant clay mineral while plaster is clay free; concerning microorganisms, the fungal flora Aspergillus glaucus represent the most dominant fungi constituting (22.22%), Aspergillus flavus, Aspergillus flavus, Aspergillus fumigatus, Aspergillus occhraceus, and Aspergillus caudidus were also isolated.

“…They verified that the technique can retain heavy metals in the soil and reduce their mobility, and the order of desorption of the three metals by the soil was: Cd>Ni>Pb. Hui et al [ 193 ] found with the increasing solution salinity progressively, reduced the removal efficiency of Pb, but the removal efficiency could be still as high as 89% ( Fig 11 ).…”

In nature, biomineralization is a common phenomenon, which can be further divided into authigenic and artificially induced mineralization. In recent years, artificially induced mineralization technology has been gradually extended to major engineering fields. Therefore, by elaborating the reaction mechanism and bacteria of mineralization process, and summarized various molecular dynamics equations involved in the mineralization process, including microbial and nutrient transport equations, microbial adsorption equations, growth equations, urea hydrolysis equations, and precipitation equations. Because of the environmental adaptation stage of microorganisms in sandy soil, their reaction rate in sandy soil environment is slower than that in solution environment, the influencing factors are more different, in general, including substrate concentration, temperature, pH, particle size and grouting method. Based on the characteristics of microbial mineralization such as strong cementation ability, fast, efficient, and easy to control, there are good prospects for application in sandy soil curing, building improvement, heavy metal fixation, oil reservoir dissection, and CO2 capture. Finally, it is discussed and summarized the problems and future development directions on the road of commercialization of microbial induced calcium carbonate precipitation technology from laboratory to field application.

“…Hence, bacterial cells and EPS can affect the polymorphism and morphology of minerals, which may affect the removal efficiency of HMs. Bai et al (2021) revealed that Pb removal declined with the increasement of the vaterite faction within bio-precipitates. Bacterial cells and carbonate minerals also inevitably engage in adsorption, thereby accounting for the trap of HMs ( Qiao et al, 2021 ).…”

“…This is crucial for the application of MICP in metal immobilization technology. Therefore, the introduction of active Ca 2+ to the bioremediation process is a straightforward method for alleviation of high HM toxicity, protecting ureolytic bacteria against HM stress and elevating the remediation performance ( Bai et al, 2021 ; Fang et al, 2021 ; Kim et al, 2021 ; Xue et al, 2022 ; Zhang et al, 2022 ;). The researchers discovered Ca 2+ can compete with Cd 2+ for surface binding and transport into the cells, therefore significantly enhanced the Cd 2+ resistance of ureolytic bacterium ( Fang et al, 2021 ; Figure 4E ).…”

With the development of economy, heavy metal (HM) contamination has become an issue of global concern, seriously threating animal and human health. Looking for appropriate methods that decrease their bioavailability in the environment is crucial. Microbially induced carbonate precipitation (MICP) has been proposed as a promising bioremediation method to immobilize contaminating metals in a sustainable, eco-friendly, and energy saving manner. However, its performance is always affected by many factors in practical application, both intrinsic and external. This paper mainly introduced ureolytic bacteria-induced carbonate precipitation and its implements in HM bioremediation. The mechanism of HM immobilization and in-situ application strategies (that is, biostimulation and bioaugmentation) of MICP are briefly discussed. The bacterial strains, culture media, as well as HMs characteristics, pH and temperature, etc. are all critical factors that control the success of MICP in HM bioremediation. The survivability and tolerance of ureolytic bacteria under harsh conditions, especially in HM contaminated areas, have been a bottleneck for an effective application of MICP in bioremediation. The effective strategies for enhancing tolerance of bacteria to HMs and improving the MICP performance were categorized to provide an in-depth overview of various biotechnological approaches. Finally, the technical barriers and future outlook are discussed. This review may provide insights into controlling MICP treatment technique for further field applications, in order to enable better control and performance in the complex and ever-changing environmental systems.
