“…The existence of poorly-developed rhomboedral faces in some spheroid surfaces suggest that some vaterite spherules are partially or totally transformed into calcite aggregates or rhombohedric crystals. The formation mechanisms are not completely known (Friedman, 1997) but several authors indicate that bacterial activity seems to be necessary for the formation of vaterite aggregates (Giralt et al, 2001;Braissant et al, 2003;Sanchez-Moral et al, 2003;Rodriguez-Navarro et al, 2007) although bacterial vaterite precipitation is not strain-specific (Groth et al, 2001;Cacchio et al, 2003).…”

“…Among the various reactive components associated with bacterial cell walls, bacterial EPS is of particular importance be- cause it affects biofilm formation and cell adhesion to solid substrates (Gebauer et al, 2010). EPS exhibits a greater binding ability to complex heavy metals, and mechanisms such as proton exchange, global electric field or microprecipitation of metals may occur in metal adsorption by EPS (Rodriguez-Navarro et al, 2007).…”

“…Calcium carbonate forms three anhydrous polymorphs: calcite, aragonite, and vaterite (Gebauer et al, 2010). Among them, calcite and vaterite are the most common bacterial calcium carbonate polymorphs (Rodriguez-Navarro et al, 2007), but other polymorphs such as monohydrocalcite and aragonite were also reported (Sánchez-Navas et al, 2009). Many studies investigated the species-specific precipitation of carbonate biominerals by various bacteria (Dhami et al, 2013).…”

Abandoned mine sites are frequently polluted with high concentrations of heavy metals. In this study, 25 calcite-forming bacteria were newly isolated from the soil of an abandoned metal mine in Korea. Based on their urease activity, calcite production, and resistance to copper toxicity, four isolates were selected and further identified by 16S rRNA gene sequencing. Among the isolates, Sporosarcina soli B-22 was selected for subsequent copper biosequestration studies, using the sand impermeability test by production of calcite and extracellular polymeric substance. High removal rates (61.8%) of copper were obtained when the sand samples were analyzed using an inductively coupled plasma-optical emission spectrometer following 72 h of incubation. Scanning electron microscopy showed that the copper carbonate precipitates had a diameter of approximately 5-10 m m m m mm. X-ray diffraction further confirmed the presence of copper carbonate and calcium carbonate crystals.

“…Although calcium carbonates are the most studied crystals, ureolytic bacteria are capable of forming different types of crystals depending on the medium in which they are (Table 1). For example, vaterite is found to be in a lower percentage, metastable or in the transitional phase of calcite [8] and it has been described that it depends on the concentration of EPS and the organic matter that would influence its formation, which could be stabilized in the presence of certain organics [8,52]. The maturation of CaCO 3 from vaterite to calcite follows the Ostwald's step rule, where metastable forms nucleate and then are replaced with more stable forms, with this sequential formation in time is also known as paragenesis [53].…”

Biomineralization Mediated by Ureolytic Bacteria Applied to Water Treatment: A Review

Abstract:The formation of minerals such as calcite and struvite through the hydrolysis of urea catalyzed by ureolytic bacteria is a simple and easy way to control mechanisms, which has been extensively explored with promising applications in various areas such as the improvement of cement and sandy materials. This review presents the detailed mechanism of the biominerals production by ureolytic bacteria and its applications to the wastewater, groundwater and seawater treatment. In addition, an interesting application is the use of these ureolytic bacteria in the removal of heavy metals and rare earths from groundwater, the removal of calcium and recovery of phosphate from wastewater, and its potential use as a tool for partial biodesalination of seawater and saline aquifers. Finally, we discuss the benefits of using biomineralization processes in water treatment as well as the challenges to be solved in order to reach a successful commercialization of this technology.
