“…The chemical technique is not only expensive but requires many injection vessels for the treatment of large volumes; however, by using MICP, reagents and catalysts can be transported to where they are required (Dhami et al, 2013). Canakciet, Sidik & Halil Kilic (2015), evaluated the biocementation process in sandy organic soils and found that calcite precipitation increased by 20 % in treated samples, influencing the compressibility and cutting force of the sample used.…”

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. ResumenLas bacterias con actividad ureásica son microorganismos que se encuentran en el suelo, y que en presencia de urea y calcio, pueden producir carbonato de calcio, proceso conocido como precipitación de calcio inducida microbiológicamente (PCIM). 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 .

“…Various studies have been performed so far in which MICP is used for improving resistance to liquefaction (Montoya et al 2013), improving foundation bearing capacity and slope stability (van Paassen et al 2010;Whiffin et al 2007), creating water-impermeable crust on sand surface (Stabnikov et al 2011), healing cracks in concrete and masonry (Bang et al 2010;Amidi and Wang 2015), treating waste (Chu et al 2009), immobilizing heavy metals (Fujita et al 2010), performing shallow carbon sequestration (Washbourne et al 2012), promoting the fine tailings consolidation (Liang et al 2015), and improving the compressibility and shear strength of organic soil (Canakci et al 2015).…”

Wind erosion is a serious problem throughout the world which results in soil and environment degradation and air pollution. The main objective of this study was to evaluate feasibility of microbial-induced carbonate precipitation, as a novel soil-strengthening technique, to reduce wind erosion risk of a sandy soil. For this purpose, the erosion of biocemented soil samples was investigated experimentally in a wind tunnel under the condition of wind velocity of 45 km h -1 . The weight loss of treated samples relative to the weight loss of control treatment was 1.29 and 0.16 % for low and high bacterial mix concentrations, respectively, indicating a significant improvement in erosion control in biologically treated samples. The effect of biological treatment on wind erosion control was even superior at the higher velocities. Thereafter, the penetration resistance of the surface layers as a simple index of resistance against wind erosion was measured. Significant improvements in the penetration resistance of the treated soil samples were observed. Although low bacterial mix concentrations did not significantly improve the penetration resistance of the samples, significant improvements in the penetration resistance of the treated soil samples were observed reaching to the highest measured strength (56 kPa) in high bacterial mix concentrations samples. Finally, the morphology of precipitated CaCO 3 crystals using scanning electron microscopy and X-ray powder diffraction analysis showed that the CaCO 3 was mainly precipitated as vaterite crystals forming pointto-point contacts between the sand granules.

“…Mineralogy: MICP has been successfully applied in silica sands, gravel (van Paassen et al, 2012) and organic soil such as peat (Canakci et al, 2015); in porous rock such as Berea sandstone (Cunningham et al, 2014;Minto et al, 2017a;Nemati and Voordouw, 2003); and for fractured rock including dolerite (MacLachlan, 2017), dacite (Cuthbert et al, 2013), granite (Minto et al, 2016), fractured sandstone (Phillips et al, 2016 and fractured limestone (Ross et al, 2001).…”

Over the last 10-15 years, a new field of "biogeotechnics" has emerged as geotechnical engineers seek to find ground improvement technologies which have the potential to be lower carbon, more ecologically friendly, and more cost-effective than existing practices. This review summarizes the developments which have occurred in this new field, outlining in particular the microbial processes which have been shown to be most promising for altering the hydraulic and mechanical responses of soils and rocks. Much of the research effort in this new field has been focused on microbially induced carbonate precipitation (MICP) via ureolysis, while a comprehensive review of MICP is presented here, the developments which have been made regarding other microbial processes, including MICP via denitrification and biogenic gas generation are also presented. Furthermore, this review outlines a new area of study: the potential deployment of fungi in geotechnical applications which has until now been unexplored.
