“…The proportion of C and O elements to metal ions was significantly higher than that of carbonate, suggesting that they may originate from residual cell tissues. Previous studies have shown that the composition of elements collected from the surface of mineralcoated cells has a high content of C and O elements, which aligned with the findings of this study [20]. EDS results indicated that the fragments in the holes or above the precipitated surface were cell fragments.…”

“…In addition, no micrometer-sized carbonate crystals were observed on the cell surfaces. Previous studies have shown that cells involved in MICP are typically covered by sub-micrometer particles [20]. One possible explanation was that during the progress of precipitate formation, larger precipitates ranging from microns to tens of microns were formed, but accompanied by the disappearance of many relatively smaller precipitates (hundreds of nanometers) [49].…”

Polymetallic nodules and polymetallic sulfides are currently the major mineral resources found on the seabed. The motivation behind deep-sea mining arises from the pursuit of valuable metals, driven by both economic and geopolitical considerations. However, before mining can be authorized, it is crucial to understand the microbial adaptation and biomineralization process related to heavy metals in deep-sea environments. To search for potential candidate materials for bioremediation in deep-sea environment, two strains with high resistance to manganese and the ability to form rhodochrosite precipitates were isolated from the deep-sea polymetallic nodule areas and hydrothermal polymetallic sulfide areas. Genomic analysis revealed that the strains employed various effective survival strategies, such as motility, chemotaxis, biofilm formation, metal redox, and transporters, to adapt to heavy metal environments. The bacterial strains Ery5 and Ery15 promote the formation of carbonate crystals by creating an excessively alkaline environment and releasing extracellular polymeric substances (EPSs). Furthermore, strains Ery5 and Ery15 were identified using polyphasic taxonomy methods and proposed as a new species belonging to the genus Croceicoccus. This study presents potential candidates for bioremediation in deep-sea environments.

Heavy metal pollution results in enormous environmental impacts and significant human health problems. Because of their extreme toxicity and lack of biodegradability, heavy metal ions in water are considered problematic. Although the removal of various heavy metal ions from wastewater has been widely investigated, heavy metal contamination still requires effective and suitable remediation. With special attention on heavy metal removal, this study reviews recent advances, breakthroughs, and potential applications of various physical, chemical, and biological methods. Each treatment method has specific mechanisms of interaction with metal ions, which are described in this review. The discussion in this review leads to the conclusion that adsorption has the best potential which leads to the sustainable remediation of heavy metals. In summary, the review provides a new perspective on heavy metal reduction and encourages the development of innovative strategies for heavy metal removal. The main current problems and prospects in this field are highlighted in this review.
