Detection of Sulfate-Reducing Bacteria as an Indicator for Successful Mitigation of Sulfide Production.

ABSTRACT: Sulfate-reducing bacteria (SRBs) are one of the main sources of biogenic H₂S generation in oil reservoirs. Excess H₂S production in these systems leads to oil biosouring, which causes operational risks and health hazards and can increase the cost of refining crude oil. Nitrate salts are often added to the system to suppress sulfidogenesis. Because SRB populations can persist in biofilms even after nitrate treatment, identifying shifts in the sessile community is crucial for successful mitigation. However, sampling the sessile community is hampered by its inaccessibility. Here, we use the results of a long-term (148 days) ex situ experiment to identify particular sessile community members from observations of the sample waste stream. Microbial community structur
