“…The culture is generally added to the materials in a column so that when calcium carbonate precipitates, important factors that are taken into account in the durability of cement can be assessed, such as: water absorption (AboEl- Enein et al, 2012Enein et al, , 2013Achal et al, 2011), compression resistance (Abo-El-Enein et al, 2012Achal et al, 2011a), crack or fissure remediation (Achal et al, 2013), impermeability to water by measuring penetration resistance (Achal et al, 2011a) and total porosity (Achal et al, 2013); the results obtained were positive, including a porosity reduction of up to 50% in the materials used, and with a significant decrease in chlorine and water permeability, which would allow their potential use in structures or buildings. However, the inclusion of other materials such as waste ash from a thermoelectric plant (Achal et al, 2011a), ashes and waste from the silica industry (Chahal & Siddique, 2013), rice husk ashes (Siddique et al, 2016), solid industrial waste such as cement and lime kiln dust (Cuzman, Rescic, Richter, Wittig & Tiano, 2015) have also been assessed.…”

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 .

“…Due to physicochemical properties of EPSs, biofilms can behave as viscous liquids to resist the flow-induced shear stress, and substantially plug the pore (Costerton et al, 1995;Flemming et al, 2011;Rozen et al, 2001;Stoodley et al, 1999;Tsai, 2005). Engineering bioplugging processes need to control biofilms selectively and substantially growing in desired places (Abdel Aal et al, 2010;Cuzman et al, 2015;Joshi et al, 2017). Therefore, mechanisms on biofilm development and its adhesive strength with solids surface is vitally important.…”

“…Its potential for grain consolidation for a type of CKD mixed with granulated blast furnace slag (GGBS), has potential application in bioclogging and biocementation. The results demonstrate the formation of stable biocalcite in the presence of CKD, with a yield that depends on the pH value and the content of free calcium ions, the benefits of this technology in construction costs and reduction of environmental contamination are promising [92].…”

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.
