NGS: Characterizing Microbial Communities and Assessing MIC Threats

Next generation sequencing (NGS) was performed on liquid samples from key locations with different operating conditions.

NGS revealed diverse microbial communities and the presence of microbial groups commonly implicated in MIC including sulfate reducing bacteria (SRB), methanogens, and acetogens.

In conjunction with a review of operating conditions, corrosion monitoring, and inspections, the NGS results added a key line of evidence indicating a threat of microbiologically influenced corrosion (MIC).
