Abstract

In this study corrosion behavior of low alloy steel, in the presence of anaerobic sulfate-reducing Desulfotomaculum sp. which was isolated from an oil production well, was investigated. In order to determine corrosion rates and mechanisms, mass loss measurements and electrochemical polarization studies were performed without and with bacteria in the culture medium. Scanning electron microscopic observations and energy dispersive X-ray spectra (EDS) analysis were made on steel coupons.
