Popis:	The current study explores microbiologically influenced corrosion (MIC) of carbon steel API 5L X65 with and without the presence of sulfate-reducing bacteria (SRB) in CO_2 environments. The Electrochemical Impedance Spectroscopy (EIS), potentiodynamic polarisation and Field Emission Scanning Electron Microscopy (FESEM) techniques were employed to analyse the carbon steel’s corrosion behaviour. The R_p values from the EIS signify lower values denoting the steel’s greater corrosion rate. FESEM micrographs found a uniform corrosion on specimens without SRB whereas a pitting corrosion on specimens with SRB. The study concludes that SRB accelerate the corrosion progression due to MIC.
