Abstract
THE stimulation of iron corrosion under anaerobic conditions by Vibrio desulfuricans is well known, and the organism has recently been shown1 to be a facultative autotroph. Several laboratory investigations of this type of corrosion have been described2–4. But, to our knowledge, there has, as yet, been no published comparison of the corrosion under heterotrophic and under autotrophic conditions. We have felt that such a comparison should throw further light on the mechanism of this type of corrosion and on the explanation first proposed by von Wolzogen Kuhr2. This worker considered that the stimulation of corrosion was due to the utilization by the bacteria of cathodically produced hydrogen, by which the corrosion reaction would otherwise be polarized.
