Microbiologically Influenced Corrosion (MIC) is one of the main threats for marine infrastructures, leading to severe safety and environmental risks associated with structural failures and/or leakages dangerous fluids, together potential huge economic losses reputational damage involved parts. For a safe design proper installation infrastructure systems in contact seabed, deep knowledge site-specific microbial community sediments should be beneficial. Therefore, addition simple detection or sole quantification Sulphate-Reducing Bacteria (SRB), whole characterization members MIC phenomena desirable. In this study, 16S rRNA-based comparison between bacterial communities thriving offshore nearshore was performed, focus on groups putatively responsible MIC. The were significantly enriched human organic compounds contamination belonging Bacteroidota , Desulfobacterota Firmicutes phyla, while hosted Alphaproteobacteria Nitrospinota Nitrospirota members, representative low anthropogenic impact. Quantitative PCR targeting dsrA gene detailed analyses revealed that SRB mainly affiliated Desulfobulbus Desulfosarcina genera potentially biocorrosion, compared ones. These results suggest high concentration derived by an elevated impact likely favour Such observations highlight importance microbiological investigations as prevention strategy against processes, aiming both at characterizing sites establishment new infrastructures monitoring those already installed.
