Ureolysis-driven calcite precipitation has potential to seal porosity and fracture networks in
rocks thus preventing groundwater flow and contaminant transport. In this study urea …

The use of Sporosarcina pasteurii to precipitate calcium carbonate in the anoxic subsurface
via ureolysis has been proposed for reducing porosity and sealing fractures in rocks. Here …

The kinetics of urea hydrolysis (ureolysis) and induced calcium carbonate (CaCO 3)
precipitation for engineering use in the subsurface was investigated under aerobic …

Addition of molasses and urea was tested as a means of stimulating microbial urea
hydrolysis in the Eastern Snake River Plain Aquifer in Idaho. Ureolysis is an integral …

A suite of experiments was performed to investigate the partitioning of Sr2+ (to mimic the
radionuclide 90Sr) between calcite and artificial groundwater in response to the hydrolysis …

The kinetics of calcite precipitation induced in response to the hydrolysis of urea by Bacillus
pasteurii at different temperatures in artificial groundwater (AGW) was investigated. The …

Aims Ureolysis drives microbially induced calcium carbonate precipitation (MICP). MICP
models typically employ simplified urea hydrolysis kinetics that do not account for cell …

Coprecipitation in carbonate minerals offers a means of slowing the transport of divalent
radionuclides and contaminant metals (eg, 90Sr2+, UO2+, Co2+) in the subsurface. It may …

The nucleation and growth of calcite precipitates induced by the bacterial hydrolysis of urea
(ureolysis) from a Sr-contaminant inclusive, and a Sr-free artificial groundwater (AGW) …

Despite the potential contribution of microbially induced carbonate precipitation (MICP) to a
range of environmental technologies, little is known about the controls on the rate of …
