Abstract: | The data reported in this investigation revealed that phosphate and hydrogenase can affect the corrosion of mild steel. Phosphate reacted on mild-steel with concomitant evolution of hydrogen gas (H2) and the formation of vivianite. The enzyme hydrogenase was shown to accelerate this reaction by oxidizing the H2 produced, its known substrate. The components of biological growth media, one of which has been identified as phosphate, can interact with mild steel and cause corrosion. The implications of these findings to the corrosion industry are discussed.Correspondence to: E. Laishley |
