Anaerobic degradation of oil hydrocarbons by sulfate-reducing and nitrate-reducing bacteria
Crude oil is a complex mixture mainly composed of various saturated and aromatic hydrocarbons. Whereas degradation of hydrocarbons by oxygen-respiring microorganisms has been known for nearly one century, utilization of hydrocarbons under anoxic conditions has been investigated only during the past ten years. The present paper summarizes investigations into the anaerobic degradability of crude ...
متن کاملCRUDE GLYCEROL AS SUBSTRATE FOR SULFATE-REDUCING BACTERIA FROM A MATURE OIL FIELD AND ITS POTENTIAL IMPACT ON SOURING
Crude glycerol (CG) is an abundantly available and cheap by-product from biodiesel production. Value-added applications for CG are highly wanted by industry and several processes such as the use of CG for enhanced oil recovery have been proposed. The aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (SRB) indigenous to oil reservoirs using CG as substrate. Th...
متن کاملFractionation of Hydrogen Isotopes by Sulfate- and Nitrate-Reducing Bacteria
Hydrogen atoms from water and food are incorporated into biomass during cellular metabolism and biosynthesis, fractionating the isotopes of hydrogen-protium and deuterium-that are recorded in biomolecules. While these fractionations are often relatively constant in plants, large variations in the magnitude of fractionation are observed for many heterotrophic microbes utilizing different central...
متن کاملSulfurous Analysis of Bioelectricity Generation from Sulfate-reducing Bacteria (SRB) in a Microbial Fuel Cell
The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible...
متن کاملIsolation and characterization of strains CVO and FWKO B, two novel nitrate-reducing, sulfide-oxidizing bacteria isolated from oil field brine.
Bacterial strains CVO and FWKO B were isolated from produced brine at the Coleville oil field in Saskatchewan, Canada. Both strains are obligate chemolithotrophs, with hydrogen, formate, and sulfide serving as the only known energy sources for FWKO B, whereas sulfide and elemental sulfur are the only known electron donors for CVO. Neither strain uses thiosulfate as an energy source. Both strain...
