The utilization of aromatic hydrocarbon by nitrate- and sulfate-reducing bacteria in single and multiple nitrate injection for souring control

The application of nitrate-mediated souring control has been proposed as a promising tool. However, the efficiency of this method remains controversial due to several unresolved issues, such as the determination of effective nitrate concentration, the optimal injection period, etc. In this study, Dr. Eng. Kamarisima and colleagues investigated the bacteria community as well as the depletion of specific hydrocarbons as the electron donor for sulfate-reducing bacteria (SRB) and nitrate-reducing bacteria (NRB) by varying the nitrate concentration and injection timing, suggesting optimum condition for souring control.
