In this work the corrosion of carbon steel A-366 exposed to a mixed culture of sulphate-reducing bacteria (MCSRB) isolated from produced water of a flow station of the crude oil Venezuelan industry and correlated with the sessile and planktonic growth curves of the culture and the metal attack morphology using a synthetic produced water (SPW) simulating the field water conditions. In addition was analyzed the most appropriate method for the MCSRB activation and different conditions that influence their growth at the sessile and planktonic level. Were constructed growth curves for 1% and 10% of inoculum in SPW analyzing the pH iron sulphur and sulphates in the solution such as weight loss along the time and the attack morphology. It was determined that with 10% of inoculum there is a correlation with sessile and planktonic growth and loss weight total iron and attack morphology characterized by small pits distributed uniformly over the metal surface which show that once the SRB has colonized the metal surface it is permanently active and corrode although sessile bacterial growth remains constant this being indicative of the combined influence of iron sulphite products and bacteria interacting negatively on the metal that not permit it protection. Keywords: Correlation Microbiologically Induced Corrosion Sulphate-Reducing Bacteria produced water weight lost and attack morphology.
