“…Subsurface MICP barriers can be an alternative to prevent mitigation of salt-laden water into freshwater aquifers (Rusu et al 2011;Tobler et al 2011). To achieve this, the selected microorganisms must be able to tolerate high saline conditions and induce calcium carbonate precipitation under such an environment.…”

Bio-deposition of minerals is a widespread phenomenon in the biological world and is mediated by bacteria, fungi, protists, and plants. Calcium carbonate is one of those minerals that naturally precipitates as a by-product of microbial metabolic activities. Over recent years, microbially induced calcium carbonate precipitation (MICP) has been proposed as a potent solution to address many environmental and engineering issues. However, for being a viable alternative to conventional techniques as well as being financially and industrially competitive, various challenges need to be overcome. In this review, the detailed metabolic pathways, including ammonification of amino acids, dissimilatory reduction of nitrate, and urea degradation (ureolysis), along with the potent bacteria and the favorable conditions for precipitation of calcium carbonate, are explained. Moreover, this review highlights the potential environmental and engineering applications of MICP, including restoration of stones and concrete, improvement of soil properties, sand consolidation, bioremediation of contaminants, and carbon dioxide sequestration. The key research and development questions necessary for near future large-scale applications of this innovative technology are also discussed.

“…The process is applicable to numerous engineered applications, from carbon sequestration (Mitchell et al ) and groundwater remediation (Achal et al ), to soil stabilization (Whiffin et al ) and improved subsurface barriers (Rusu et al ). The most common organism used in subsurface engineered biomineralization applications is the ureolytic bacterium Sporosarcina pasteurii (Phillips et al ).…”

Aims: Development of biomineralization technologies has largely focused on microbially induced carbonate precipitation (MICP) via Sporosarcina pasteurii ureolysis; however, as an obligate aerobe, the general utility of this organism is limited. Here, facultative and anaerobic haloalkaliphiles capable of ureolysis were enriched, identified and then compared to S. pasteurii regarding biomineralization activities. Methods and Results: Anaerobic and facultative enrichments for haloalkaliphilic and ureolytic micro-organisms were established from sediment slurries collected at Soap Lake (WA). Optimal pH, temperature and salinity were determined for highly ureolytic enrichments, with dominant populations identified via a combination of high-throughput SSU rRNA gene sequencing, clone libraries and Sanger sequencing of isolates. The enrichment cultures consisted primarily of Sporosarcina-and Clostridium-like organisms. Ureolysis rates and direct cell counts in the enrichment cultures were comparable to the S. pasteurii (strain ATCC 11859) type strain. Conclusions: Ureolysis rates from both facultatively and anaerobically enriched haloalkaliphiles were either not statistically significantly different to, or statistically significantly higher than, the S. pasteurii (strain ATCC 11859) rates. Work here concludes that extreme environments can harbour highly ureolytic active bacteria with potential advantages for large scale applications, such as environments devoid of oxygen. Significance and Impact of the Study: The bacterial consortia and isolates obtained add to the possible suite of organisms available for MICP implementation, therefore potentially improving the economics and efficiency of commercial biomineralization.Journal of Applied Microbiology ISSN 1364-5072 À , Br À , PO 4 3À and dissolved Fe.

“…In recent years, domestic research has mainly focused on chemical sand fixing, such as polymer materials, organic-inorganic composite materials, and modified waste plastic materials [9][10][11][12][13]. International researchers have conducted numerous studies on microbial soil modification [14][15][16], using microbial metabolic activities to induce or control a series of chemical reactions in the soil to improve the soil, thereby achieving sand fixation [17][18][19].…”

Harsh conditions, such as the lack of raw materials and high transportation costs, impede the construction of desert railway sand control projects. Against this background, aeolian sand along the desert railway was used in a study on “sand control with sand.” According to the mechanical properties and durability tests, as well as field observations, the enhancement effect of fiber (cloth) on the performance of a sand-fixing board made of aeolian sand was analyzed. Based on the results, the mechanical strength of the sand-fixing board increased with increasing fiber content and length, and the maximum increase in compressive strength and flexural strength reached 2.15 and 0.59 times, respectively. The addition of fiber significantly improved the frost resistance, effectively reducing the mass loss rate of the board by an average of 60%. With increasing fiber content and length, the improvement effect of the freeze–thaw strength loss rate of the sand-fixing board first decreased and then increased. The results show that the performance of sand-fixing boards reached the engineering application standard under the reinforcement of the fiber (cloth), successfully establishing the concept of “sand control with sand.”
