Experimental and numerical simulation study of microbial enhanced oil recovery using bio-surfactants.
(2005)
A 2-phase, 10-component microbial enhanced oil recovery numerical simulator was modified to include reservoir salinity and facilitate surfactant and polymer injection. The effects of reservoir brine salinity and divalent ...
Rhizosphere ecology of PCB-degrading bacteria at a contaminated site and implications for bioremediation.
(2003)
Rhizosphere bioremediation is an emerging technology that relies on plant roots to enhance bacterial biodegradation of soil contaminants like polychlorinated biphenyls (PCBs), providing an inexpensive alternative to ...
Bacillus lipopeptide biosurfactants: Purification, structure-activity relationship, and in-situ production in oil reservoirs.
(2006)
Alternatively, biosurfactant activity can be manipulated by formulation of biosurfactant mixtures with different properties. The efficacy of biosurfactants from individual strains, and mixtures of biosurfactants from ...
The microbial conversion of synthesis gas to ethanol: Characterization and optimization.
(2005)
By screening 310 enrichments from 37 different sources of inocula (e.g., sediments, lagoons, compost, silage, and animal feces), seven potential microbial candidates (strain P7, P11, P14, P20, P21, MU1 and SK1) were isolated ...
Impact of physiological state and macro-nutrient ratio on microbial surface thermodynamics and transport.
(2002)
As both deposition and retardation occur during bacterial transport, the deposition coefficient and retardation factor have been widely used individually in describing the transport of bacteria through porous media. Rijnaarts ...
Microbiology of water and wastewater: Discovery of a new genus numerically dominant in municipal wastewater and antimicrobial resistances in numerically dominant bacteria from Oklahoma lakes.
(2005)
Three bacterial isolates from municipal wastewater were investigated for their phenotypic, biochemical, and molecular characters. All strains were isolated from municipal wastewater, and the type strain, NRS1T, was isolated ...
The reduction of uranium by sulfate-reducing bacteria in the terrestrial subsurface and a pure culture bacterium.
(2002)
The microbial reduction of uranium was investigated in a contaminated aquifer and with a pure culture model organism, Desulfovibrio vulgaris Hildenborough. The concentrations of Fe(III), U(VI), nitrate and sulfate were ...
The microbial metabolism of benzene and crude oil under diverse anaerobic conditions.
(2000)
The research reported here expands the range of knowledge for anaerobic hydrocarbon metabolism, as well as provides a sound foundation for the microbial destruction of compounds once thought to be completely recalcitrant ...
Assessing the influence of physical and chemical properties of sediments on microbial distribution and activity in the terrestrial subsurface.
(2005)
To maximize the possibility for success, accurate assessment of the distribution and activity of microorganisms in the subsurface is essential for implementing bioremediation strategies at contaminated sites. It is clear ...
