Microbially 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 کاملCombined strategy for the precipitation of heavy metals and biodegradation of petroleum in industrial wastewaters.
The precipitation of chromium(III), copper(II), manganese(II) and zinc(II) by biogenic hydrogen sulfide generated by sulfate-reducing bacteria, Desulfovibrio sp., and the degradation of total petroleum hydrocarbons (TPH) in the presence of heavy metal by Pseudomonas aeruginosa AT18 have been carried out. An anaerobic stirred tank reactor was used to generate hydrogen sulfide with Desulfovibrio ...
متن کاملCementation of Sand Soil by Microbially Induced Calcite Precipitation at Various Degrees of Saturation
4 A newly emerging microbiological soil stabilization method, known as microbially 5 induced calcite precipitation (MICP), is tested for geotechnical engineering 6 applications. MICP is a promising technique that utilizes the metabolic pathways of 7 bacteria to form calcite precipitation throughout the soil matrix, leading to an increase 8 in soil strength and stiffness. This paper investigates...
متن کاملMicrobially 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 ...
