Abstract:

In a simulation of biogenic corrosion of concrete by Thiobacillus thiooxidans, the T. thiooxidans grown on concrete blocks with a H2S substrate caused a higher concrete wt. loss and pH decrease than the T. thiooxidans grown on the blocks with S2O32- or CH3SH as the substrate. TEM enabled the differentiation of Thiobacillus, Nitrosomonas, and Nitrobacter bacteria on material specimens from different sources.
