“…However, its production is responsible for approximately 6% of current CO 2 emissions, and specifically the construction industry worldwide reaches ca. 50% of total emissions (Achal et al, 2015); therefore, it is necessary to look for sustainable alternatives in terms of construction materials.…”

“…An important function of these enzymes is to promote biomineralization in nature, allowing the precipitation of calcium carbonate in soils, geological sediments and natural waters (Mobley & Hausinger, 1989). Although there is a wide variety of microorganisms with urease activity, the Bacillus group is known for its high levels of urease (Achal et al, 2015), especially Sporosarcina pasteurii, formerly Bacillus pasteurii (21 mM hydrolyzed urea.min -1 ) (Achal et al, 2015;Dupraz, Parmentier, Ménez & Guyot, 2009;Ferris, Phoenix, Fujita & Smith, 2004); this soil bacteria is non-pathogenic and grows at an optimum pH of 9.0 tolerating extreme conditions, and therefore, it has been used for MICP (Bang, Galinat & Ramakrishnan, 2001;Hammes et al, 2003b;Kumari, Pan, Lee, & Achal, 2014;Mitchell & Ferris, 2005). It has been shown that urease activity in bacteria is associated with soluble extracts in cells, which would indicate that the enzyme is in the cytoplasm of the microorganisms (Mobley & Hausinger, 1989).…”

“…In the second, the microorganisms secrete one or more metabolic products that react with the ions or compounds in the environment, with the subsequent deposition of the mineral as a metabolic byproduct (Frankel, 2003). From a sustainable construction point of view BIM is the most important and studied type (Achal, Mukherjee, Kumari, & Zhang, 2015).…”

Bacteria with ureasic activity are microorganisms found in soil that in presence of urea and calcium, they can produce calcium carbonate, a process known as microbiologically induced calcium carbonate precipitation (MICP). This article discusses this process and its mechanism, as well as bacterial urease, calcium carbonate crystals formed, and factors that affect the efficiency of MICP, as type of bacteria, bacterial cell concentrations, pH, temperature and calcium and urea concentrations. In addition, applications as removal of heavy metals in water, bioconsolidation, biocement and CO 2 sequestration are also discussed.Keywords: Biomineralization; Bacillus; urease; carbonates; heavy metals; bioconsolidation; biocementation.

Este artículo trata este proceso y su mecanismo, además de las ureasas de origen bacteriano, los cristales de carbonato de calcio formado, los factores que afectan la eficiencia la PCIM, como el tipo de bacteria, las concentraciones de células bacterianas, el pH, la temperatura y las concentraciones de calcio y urea. Además, se incluye las aplicaciones como la remoción de metales pesados en aguas, la bioconsolidación, biocemento y secuestro de CO 2 .

Résumé -La précipitation de carbonate de calcium par les bactéries offre la possibilité de réparer les matériaux cimentaires fissurés par une méthode durable et non polluante. Une suspension bactérienné epaissie aété mise au point pour favoriser la biocicatrisation de microfissures entre 150 et 500 µm en utilisant la souche bactérienne Bacillus pseudofirmus. Le fluide obtenu, par synergie entre deuxépaississants colloïdaux, est fortement rhéofluidifiant et thixotrope, résistantà la décantation et forme lors d'un repos prolongé un gel physique réversible. Ces propriétés permettent de l'injecter sans drainage post-injection dans des fissures d'ouverture variant de 150à 500 µm. L'ajout d'épaississants n'a pas d'impact sur la croissance ni sur l'activité de B. pseudofirmus et entraîne la formation d'amas autour des bactéries. Cette structure similaireà un biofilm favorise potentiellement leur survie face aux contraintes du milieu extérieur. Mots clés : Mortier / microfissures / bactéries / biominéralisation /épaississantAbstract -Bacterial precipitation of calcium carbonate opens the way to a non-polluting and long lasting method for the remediation of cracked cementitious materials. We characterized a thickened bacterial suspension for its ability to be injected in fine cracks (150 to 500 µm) and to promote biocicatrisation by Bacillus pseudofirmus. The suspension, due to a synergy between two colloidal thickeners, is a strongly shear-thinning and thixotropic fluid, is resistant to settling, and can form a weak gel at rest. These properties allow its injection without drainage in 150 to 500 µm wide cracks. The thickened medium does not alter B. pseudofirmus growth or activity, and the bacteria are embedded in hutches creating a biofilm-like structure. This structure may provide a protective environment for the bacteria, enhancing their survival and activity in hostile conditions.

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.
