“…Reduction in H 2 S formation by addition of nitrate to the injection water has been reported (508,607). The beneficial effect of nitrate injection for stimulation of a competing group of nitrate-reducing bacteria has been demonstrated in several model experiments (447,508) and successful field applications (288,607). Following nitrate injection, nitrite inhibition of sulfatereducing bacteria and sulfide oxidation by nitrate-reducing bacteria have been suggested as the mechanisms for H 2 S elimination (288,447).…”

Recent advances in molecular biology have extended our understanding of the metabolic processes related to microbial transformation of petroleum hydrocarbons. The physiological responses of microorganisms to the presence of hydrocarbons, including cell surface alterations and adaptive mechanisms for uptake and efflux of these substrates, have been characterized. New molecular techniques have enhanced our ability to investigate the dynamics of microbial communities in petroleum-impacted ecosystems. By establishing conditions which maximize rates and extents of microbial growth, hydrocarbon access, and transformation, highly accelerated and bioreactor-based petroleum waste degradation processes have been implemented. Biofilters capable of removing and biodegrading volatile petroleum contaminants in air streams with short substrate-microbe contact times (<60 s) are being used effectively. Microbes are being injected into partially spent petroleum reservoirs to enhance oil recovery. However, these microbial processes have not exhibited consistent and effective performance, primarily because of our inability to control conditions in the subsurface environment. Microbes may be exploited to break stable oilfield emulsions to produce pipeline quality oil. There is interest in replacing physical oil desulfurization processes with biodesulfurization methods through promotion of selective sulfur removal without degradation of associated carbon moieties. However, since microbes require an environment containing some water, a two-phase oil-water system must be established to optimize contact between the microbes and the hydrocarbon, and such an emulsion is not easily created with viscous crude oil. This challenge may be circumvented by application of the technology to more refined gasoline and diesel substrates, where aqueous-hydrocarbon emulsions are more easily generated. Molecular approaches are being used to broaden the substrate specificity and increase the rates and extents of desulfurization. Bacterial processes are being commercialized for removal of H2S and sulfoxides from petrochemical waste streams. Microbes also have potential for use in removal of nitrogen from crude oil leading to reduced nitric oxide emissions provided that technical problems similar to those experienced in biodesulfurization can be solved. Enzymes are being exploited to produce added-value products from petroleum substrates, and bacterial biosensors are being used to analyze petroleum-contaminated environments

“…Addition of nitrate to the injection water may reduce H # S production by stimulating a competing group of anaerobic bacteria, the nitrate-reducing bacteria (NRB) (Reinsel et al, 1996). In order to investigate the potential of nitrate as an inhibitor of reservoir souring, an oil reservoir model column was constructed (S. Myhr, B.-L. P. Lillebø, E. Sunde, J. Beeder and T. Torsvik, unpublished results).…”

“…Reinsel et al (1996) added water obtained from the North Sea oil field to a sandstone column, which contains origin bacteria, while injecting low concentrations of nitrate or nitrite (0.57 to 0.71 mM) and sulfide concentrations were observed to reduce. In this experiment, SRB and NRB were isolated from SZ 36-1 oilfield produced water, symbiosis and competitive inhibition relationships between them and influence of the variety and density of added nutritients on the amount of SRB and the activity of the production of H 2 S were examined.…”

A nitrate-reducing bacteria (NRB) strain with vigorous growth, strong nitrate reduction ability, strain B9 2-1, was isolated from Suizhong36-1 oilfield, its routine identification and analysis of 16S rRNA and also the competitive inhibition experiments with the enrichment of sulfate-reducing bacteria (SRB) were carried out. The results showed that only the dosing of nitrate, nitrite as electron acceptors, the activation of nitrate-reducing bacteria, as well as the inhibition of sulfide production resulted from a limited capacity, while addition of NRB isolated from the produced fluid, growth and sulfide production activity of sulfate reducing bacteria produced a significant inhibition and antibacterial effects of nitrite, which was better than nitrate. At the same time, the small amount of molybdate dosing showed better results, which will be of significance when applied to shipping and state-defending industries.
