摘要：
We investigated sequential aerobic and anaerobic microbiologically induced corrosion of carbon steel to simulate deep geological disposal conditions. Under limited oxygen supply, lepidocrocite and magnetite corrosion products formed on the steel coupon, while under continuous oxygen supply, a mixture of lepidocrocite, maghemite and magnetite was identified. Upon oxygen consumption and establishment of sulphidogenic conditions, due to sulphate-reducing bacteria activity, all these oxides disappeared via transformation into pyrrhotite. Corrosion rate of steel in direct anaerobic cultures was higher than that of steel initially corroded in aerobic condition, suggesting a protective role of corrosion product layer -formed under sequential aerobic-anaerobic conditions.
