“…They typically are Gram-positive, aerobic, and rod-shaped prokaryotic cells with a size of 1–10 μm (Martin et al, 2012 ; Wong, 2015 ). They are particularly interesting for MCP technology due to their capability of producing CO 2 paralleled by increasing pH in the surrounding environment (Sel et al, 2015 ; Wei et al, 2015 ). Both respirations by cells and the decomposition of urea provide a source of CO 2 .…”

“…Bacteria are omnipresent in soils at surprisingly high concentrations, almost regardless of saturation, mineralogy, pH, and other environmental factors (De Jong et al, 2013 ; Sel et al, 2015 ). Microbial activities can alter the texture of soil and improve its strength by precipitating carbonates and binding soil particles (Sari, 2015 ).…”

Calcium carbonate represents a large portion of carbon reservoir and is used commercially for a variety of applications. Microbial carbonate precipitation, a by-product of microbial activities, plays an important metal coprecipitation and cementation role in natural systems. This natural process occurring in various geological settings can be mimicked and used for a number of biotechnologies, such as metal remediation, carbon sequestration, enhanced oil recovery, and construction restoration. In this study, different metabolic activities leading to calcium carbonate precipitation, their native environment, and potential applications and challenges are reviewed.

“…The demand for novel and innovative techniques for ground improvement has compelled researchers to look for new ways of satisfying society's demand for land to meet infrastructural needs, while considering environmental concerns. Over the years, engineers and researchers have either neglected the role of microbial activities within soils or have not given it adequate attention [2]. Hence, research into innovative and alternative approaches to ground improvement has focused on the use of biological processes.…”

Review of the use of microorganisms in geotechnical engineering applications

Until recently, engineers either ignored or neglected the role of microorganisms in geotechnical engineering. The microbially induced calcite precipitation (MICP) research technique is an innovative and relatively green technology which consists in a biological process through which microorganisms react with minerals (calcium source and cementation reagent) to produce calcite (CaCO 3 ) as a byproduct that modifies and improves the engineering properties of soil. Laboratory and field results obtained from various studies are promising and viable, suggesting potential for various engineering applications. This research technique has also been considered to be useful in many engineering applications such as improvement of construction materials, cementation of porous media, improvement in strength and stiffness of engineering soils, hydraulic control of engineering facilities (waste containment), liquefaction, and erosion mitigation. In this review, the various methods of production of calcium carbonates (calcite), the role played by bacteria, various state-of-the-art procedures that have evolved in this research area, as well as ongoing studies are reported. Furthermore, the use of the MICP technique in remediation of contaminants and other environmental concerns is also presented. The advantages and challenges (in form of undesired byproducts) of this research technique are highlighted herein.

“…Microbially induced CaCO3 precipitation (MICP) using urease producing bacteria has been the most focused biocementation technique in the literature. Most of these studies employed Sporosarcina pasteurii (formerly known as Bacillus pasteurii) for the urease enzyme production (Dursun Sari 2014; Sel et al 2014). …”

There are some key challenges for geotechnical applications of the microbially-induced CaCO3 precipitation technique. These challenges mainly arise from lack of enough control on precipitation pattern within soil. Monitoring precipitation progress in treatment solution (biogrout) prior to injection provides useful information on controlling the precipitation pattern.In this study, a hybrid of electrical conductivity change measurements and precipitation mass measurements was proposed for the monitoring. The results were described as characteristic curves which provide useful information on interpreting, estimating and steering the precipitation Downloaded by [Universite Laval] at 10:27 11 October 20152 pattern within soil. Effect of some influencing factors on precipitation patterns was also statistically investigated. XRD, FTIR and SEM were used for microscale identification analysis of the precipitated solids.
