Abstract
AbstractDesulfovibrio vulgarisandDesulfovibrio ferrophiluswere previously proposed to have distinct iron corrosion mechanisms becauseD. ferrophiluscorroded faster. However, the chloride concentration in theD. ferrophilus‘marine’ medium was much higher than in theD. vulgaris‘freshwater’ medium.D. vulgariscorrosion rates accelerated with increasing chloride and were faster thanD. ferrophilusin the same marine medium. Differences inD. ferrophiluscorrosion rates in two different media with the same chloride concentration suggested that minor differences in other medium constituents also impact on microbial corrosion. These results demonstrate the importance of considering medium composition in microbial corrosion studies.
