“…La presencia de sitios de nucleación/o desarrollo de cristales para la nucleación. Además, diversos parámetros ambientales tales como la temperatura y salinidad de la suspensión tienen influencia sobre el proceso de precipitación (Rivadeneyra et al, 2004, Silva-Castro, et al, 2015. Diversos procesos metabólicos influencian directamente los primeros tres factores claves, mientras que las características físicas y químicas de las células bacterianas pueden hacer que estas actúen como sitios de nucleación de cristales (Hammes y Verstraete, 2002).…”

RESUMENPartiendo de 30 aislados bacterianos de diferentes tipos (fundamentalmente Bacillus), previamente aislados e identificados por métodos microbiológicos y moleculares, provenientes de biopelículas epilíticas aisladas del Castillo de Chapultepec de la ciudad de México, DF. Se realizaron diferentes metodologías como comprobación de capacidad para formar biopelículas y su cuantificación, prueba de ureasa y la producción de cristales de carbonato de calcio en placa Petry con Luria Bertani enriquecido con carbonato de calcio al 0.2 %. Los cristales fueron enviados a difracción de rayos X y Microscopia Electrónica de Barrido.Los resultados muestran que en alguna medida todos los microorganismos probados participan en el proceso de formación de biopelículas y un total de 12 aislados destacaron como los mejores formadores de biopelículas, sobresaliendo las cepas IS16 y IIIS10 (Bacillus subtilis), IIS15a (Bacillus cereus) por ser las que mayores UFC/mL presentaron en la biopelícula. Todos los buenos formadores de biopelículas resultan también adecuados en cuanto a bioprecipitación de carbonatos, destacando las cepas IIIS4 (Bacillus megaterium), IS5 (Bacillus subtilis), IIIS9b (Bacillus subtilis), 21 (Pantoea agglomerans) y la IIIS5 (Bacillus simplex). Poco o nada se sabe hasta el momento de la participación de Pantoea agglomerans en procesos de biorrestauración mediante bioprecipitación de cristales de carbonato de calcio y debido a que se obtuvo buena respuesta a la prueba de ureasa y los cristales obtenidos fueron mayormente Calcita (99 %), este trabajo muestra la factibilidad de usar la biota nativa para su activación y así lograr la restauración de los monumentos biodeteriorados.Palabras claves: Roca caliza; bioprecipitación bacteriana; Calcita; Aragonita; Biodeterioro y biorrestauración.

“…These are the concentration of calcium ions, concentration of dissolved inorganic carbon (DIC), pH and availability of nucleation sites [71,82,83]. In addition, several environmental parameters such as salinity, temperature may also affect for the performance of calcite precipitation [81,[84][85][86]. The rate of calcite precipitation is also depending on the injecting rate of chemicals to the soil and the rate of pH rise to prompt precipitation [87].…”

Geotechnical and geo-environmental engineering applications currently being explored through bio mineralization process include cementation of sands to improve mechanical properties and hence, to enhance bearing capacity and liquefaction resistance, sequestration of carbon, soil erosion control via surficial stabilization, groundwater flow control and remediation of soil and groundwater impacted by metals and radionuclides. Bio mediated system broadly refers to a chemical reaction series that are managed and controlled through biological activities and byproducts resulting from those reactions alter the properties of material in the system. Bio mediated methods such as microbial induced calcite precipitation (MICP), biofilm formation, biogas generation and biopolymers have been developed by injecting or stimulating microbes. MICP is the most widely explored method. Microbes having urease activity enhance the hydrolysis of urea and it helps to control the pH and to precipitate carbonate. Although it is a widely explored bio mediated method it has some disadvantages.The plant-derived urease may offer many benefits over microbial urease to induce carbonate cementation. Therefore, it is advantageous to explore the knowledge regarding such a technique as an eco-friendly method for different applications in the fields of geoenvironmental/geotechnical Engineering. The main objective of this paper is to provide an overview of the importance of plant-derived urease for different applications in the fields of geoenvironmental/ geotechnical engineering. The information presented in this paper may be important for biotechnologists/geoengineers to have wide ranging updates on the current situation.

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.
