Microbially induced calcite precipitation-based sequestration of strontium by Sporosarcina pasteurii WJ-2.
Contamination by radioactive strontium ((90)Sr) is a significant environmental problem. Ureolytically driven calcium carbonate precipitation has been proposed for use in geotechnical engineering for soil remediation applications. In this study, 68 ureolytic bacterial strains were newly isolated from various environments. Of these, 19 strains were selected based on ureolytic activity shown when ...
متن کاملMicrobiologically Induced Calcite Precipitation Mediated by Sporosarcina pasteurii.
The particular bacterium under investigation here (S. pasteurii) is unique in its ability, under the right conditions, to induce the hydrolysis of urea (ureolysis) in naturally occurring environments through secretion of an enzyme urease. This process of ureolysis, through a chain of chemical reactions, leads to the formation of calcium carbonate precipitates. This is known as Microbiologically...
متن کاملMicrobiologically-Induced Soil Stabilization: Application of Sporosarcina pasteurii for Fugitive Dust Control
In this study, we have introduced a biological dust control technique utilizing a naturally occurring soil microorganism, Sporosarcina pasteurii, which is capable of inducing calcium carbonate precipitation in the environment. To evaluate the dust suppressive potential of this microbial calcite, S. pasteurii was suspended in medium and applied to locally available sand. The treated soil samples...
متن کاملBiocalcification of Sand through Ureolysis
Biological processes may provide great and previously unexplored opportunities for cost-effective, in situ improvement of the engineering properties of soil. A laboratory study was conducted to evaluate the changes in geomechanical properties of sand attributable to the formation of calcium precipitates induced through ureolysis catalyzed by Sporosarcina pasteurii (S. pasteurii). Specifically, ...
متن کاملWhole cell kinetics of ureolysis by Sporosarcina pasteurii.
AIMS Ureolysis drives microbially induced calcium carbonate precipitation (MICP). MICP models typically employ simplified urea hydrolysis kinetics that do not account for cell density, pH effect or product inhibition. Here, ureolysis rate studies with whole cells of Sporosarcina pasteurii aimed to determine the relationship between ureolysis rate and concentrations of (i) urea, (ii) cells, (iii...
