Biotic and abiotic effects on CO2 sequestration during microbially-induced calcium carbonate precipitation.
In this study, CO2 sequestration was investigated through the microbially-induced calcium carbonate precipitation (MICP) process with isolates obtained from a cave called 'Cave Without A Name' (Boerne, TX, USA) and the Pamukkale travertines (Denizli, Turkey). The majority of the bacterial isolates obtained from these habitats belonged to the genera Sporosarcina, Brevundimonas, Sphingobacterium ...
متن کاملSequestration of Radionuclides and Metal Contaminants through Microbially-Induced Carbonate Precipitation
Microbially induced carbonate precipitation (MICP), an emerging technology for soil improvement, also may be used to sequester (biomineralize) radionuclides and metal contaminants (e.g., 90 Sr 2+ , Cd 2+ ) in groundwater, a significant problem at some U.S. Department of Energy sites. Previous work using the bacterium Bacillus pasteurii suggests that in-situ sequestration of these contaminants c...
متن کاملMicrobially Induced Calcite Precipitation Employing Environmental Isolates
In this study, five microbes were employed to precipitate calcite in cohesionless soils. Four microbes were selected from calcite-precipitating microbes isolated from calcareous sand and limestone cave soils, with Sporosarcina pasteurii ATCC 11859 (standard strain) used as a control. Urease activities of the four microbes were higher than that of S. pasteurii. The microbes and urea-CaCl₂ medium...
متن کاملSize-dependent calcium carbonate precipitation induced microbiologically in aerobic granules
Calcium and ash accumulation in aerobic granules treating organic wastewater was investigated systematically in this study. It was found that ash content of granular sludge reached 43% at stable state of reactor operation with calcium carbonate precipitation as the main cause. Since granular sludge in the reactor at the steady state was the mixture of granules with different sizes, granules in ...
متن کاملProtein-Mediated Precipitation of Calcium Carbonate
Calcium carbonate is an important component in exoskeletons of many organisms. The synthesis of calcium carbonate was performed by mixing dimethyl carbonate and an aqueous solution of calcium chloride dihydrate. The precipitation product was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrar...
