Mechanism and application of denitrification inhibition to activity of sulfate-reducing bacteria

This paper discusses the mechanism and application of denitrification inhibition to the activity of sulfate-reducing bacteria in wastewater treatment of domestic and overseas oilfields. All factors affecting this process and shortcomings in the process were reviewed as well. It is suggested that the study on protein structure and environmental gene is important for the mechanism research, particularly for studying the effect of addition of inhibiting agents, such as nitrate and denitrifying bacteria, on the gene and protein structure of sulfate-reducing bacteria as well as the metabolism process. It is critical to investigate this process from the view of microbial molecular ecology. The case application has also been studied for Daqing Oilfield.
