Highlights : Microbes cause significant damage in oil and gas engineering structures. 16S rRNA gene sequence indicates the presence of mixed bacterial consortium. Biotic system, confirms the presence of various oxides of Iron. IRB consortium exhibits inhibitory action on the corrosion process. Pitting was much more evident in the abiotic system than the biotic system.
