Microbially influenced corrosion (MIC) represents a significant challenge to materials integrity within the oil and gas sector. A diverse array of microbial communities has been implicated in MIC processes, underscoring the importance of accurate microbial identification for effective diagnosis and mitigation strategies. The identification of novel genetic biomarkers, such as micH and micC, associated with corrosive microbial communities, has demonstrated significant potential as a precise and reliable method for detecting microbially influenced corrosion (MIC). We conducted controlled laboratory experiments to evaluate the corrosive potential of microbial communities under varying thermal and salinity conditions and our findings revealed the presence of biomarkers both at elevated temperatures and higher salinity levels where MIC has not been implicated before. The presence of the MIC biomarkers in such a wide range of temperature and salinity profiles expands our understanding of operational envelopes for MIC and will provide valuable input for MIC monitoring and risk assessments.
