title: Corrosion of mild and stainless steel by four tropical Desulfovibrio desulfuricans strains.
abstract: The corrosion potential of four tropical Desulfovibrio desulfuricans isolates was determined using a semicontinuous batch culture technique in a 56-day test incubated at 37 degrees C. The corrosion potentials for mild and stainless steel of marine or brackish water isolates (0.55 and 0.0026 mg cm-2 day-1) were observed to be approximately twice those of freshwater isolates (0.23 and 0.0014 mg cm-2 day-1). Under comparable experimental conditions of severe anaerobic corrosion, stainless steel was found to be over 200 times more resistant than mild steel.
