Twenty thiosulfate-utilizing bacteria that may participate in the corr
osion of concrete fabrications, were isolated from the accumulation st
ratum in the delta area of Hiroshima. Five of the isolated strains wer
e selected for characterization, and four out of the five were classif
ied into the genus Thiobacillus. Three of the five strains were furthe
r identified as Thiobacillus intermedius. The growth of these five str
ains in LB medium containing heavy metals was investigated. They showe
d strong resistance to cadmium and zinc ions.
