“…For instance, minimum inhibitory concentration (MIC) of S. pasteurii exhibited different values for multiple metals (0.03–0.06 mM for Cd 2+ , 0.2–0.5 mM for Zn 2+ and Cu 2+ , below 1 mM for Pb 2+ ; Mugwar and Harbottle, 2016 ). Moreover, removal effectiveness of metal ions upon MICP changed with HM ions species and concentrations ( Jain and Arnepalli, 2019 ; Kim et al, 2021 ; Qiao et al, 2021 ; Song et al, 2021 ), which also have a marked impact on the carbonate mineralogy, shape, and crystallinity of various precipitations. Kim et al (2021) demonstrated that Pb and exhibited a high removal efficiency of greater than 99%, while Cu, Zn, and Cd exhibited a low removal efficiency of 30 ~ 60% at a low concentration of 0.05 mM or less.…”

“…For example, Cu 2+ can trigger the generation of ROS by disrupting the bacterial respiratory chain, resulting in severe injury to DNA, protein and lipid peroxidation ( Dupont et al, 2011 ). In HM contaminated sites, the living environment of microorganisms is quite stringent, and microbiostasis caused by the toxic effects of HMs or other contaminants is a significant barrier to the remediation ( Song et al, 2021 ). Therefore, it is essential to develop innovative strategies for enhancing the tolerance of microbes to higher concentrations of pollutants and boosting their remediation effectiveness.…”

“…The bacterial community structure changed with different acclimation transfers ( Figure 4A ), resulting in a broad adaptability to a variety of environmental conditions: pH 4.0–11.0, temperature 10–45°C, and Cd concentration 0–200 mg/L. Of course, the existence of HMs will in return alter community composition and decrease the community diversity ( Hu et al, 2021 ; Song et al, 2021 ; Yin et al, 2021a ). The feasibility of Ca 2+ and HMs removal from hypersaline produced water (PW) via MICP may cause complex challenges due to the distinct high salinity features of PW (ten-fold compared to seawater).…”

“…The toxicity of HMs typically inhibits microbial activity, which slows the bioremediation process and reduces the overall efficiency. Several bioremediation strategies have been employed to enhance microbial activity during MICP-based HM remediation ( Hu et al, 2021 ; Oliveira et al, 2021 ; Song et al, 2021 ). However, adequate summary information regarding improved bioremediation is not yet available.…”

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.

“…The fundamental principle of applying the bioinspired calcium carbonate precipitation technology to the immobilization of heavy metals is to catalyze urea hydrolysis using the ureolytic bacteria toward discharging hydroxide ions and ammonium ions and precipitating calcium carbonate with heavy metals ( Schwantes-Cezario et al, 2017 ; Qiao et al, 2019 ; Schwantes-Cezario et al, 2020 ; Yang et al, 2020 ; Hu et al, 2021a ; Hu et al, 2021b ; Yuyang Zhang et al, 2021 ; Yuan et al, 2021 ). The whole process is also referred to as “biomineralization”, and heavy metal migration potential can be substantially reduced when capsulized using the calcium carbonate precipitation, minimizing their threats to surrounding environments ( Zhu and Maria, 2016 ; Arias et al, 2019 ; Teng et al, 2019 ; Song et al, 2021 ) (see Eqs 1 – 7 ). Jiang et al (2019) reported that calcium source and bacterial concentration can affect the remediation efficiency against lead and three mechanisms, namely, abiotic precipitation, biotic precipitation, and biosorption, which take part in the biomineralization process.…”

Lead and copper ions from wastewater induced by metallurgical processes are accumulated in soils, threatening plant and human health. The bioinspired calcium carbonate precipitation is proven effective in improving the cementation between soil particles. However, studies on capsulizing heavy metal ions using the bioinspired calcium carbonate precipitation are remarkably limited. The present study conducted a series of test tube experiments to investigate the effects of bacterial culture and calcium source addition on the remediation efficiency against lead and copper ions. The calcium carbonate precipitation was reproduced using the Visual MINTEQ software package to reveal the mechanism affecting the remediation efficiency. The degradation in the remediation efficiency against lead ions relies mainly upon the degree of urea hydrolysis. However, higher degrees of urea hydrolysis cause remediation efficiency against copper ions to reduce to zero. Such high degree of urea hydrolysis turns pH surrounding conditions into highly alkaline environments. Therefore, pursuing higher degrees of urea hydrolysis might not be the most crucial factor while remedying copper ions. The findings shed light on the importance of modifying pH surrounding conditions in capsulizing copper ions using the bioinspired calcium carbonate precipitation.

Metal pollution poses significant threats to the ecosystem and human health, demanding effective remediation strategies. Bioremediation, which leverages the unique metal‐resistant genes found in bacteria, offers a cost‐effective and efficient solution to heavy metal contamination. Genes such as Cad, Chr, Cop, and others provide pathways to improve the detoxification of the ecosystem. Through multiple techniques, genetic engineering makes bacterial genomes more capable of improving metal detoxification; nonetheless, there are still unanswered questions regarding the nature of new metal‐resistant genes. This article examines bacteria's complex processes to detoxify toxic metals, including biosorption, bioaccumulation, bio‐precipitation, and bioleaching. It also explores essential genes, proteins, signaling mechanisms, and bacterial biomarkers involved in breaking toxic metals.
