• Bacterial solubilization and oxidation of iron from pyrite were determined with the use of analytical methods which differentiated between total iron and reduced and oxidized forms of soluble iron. About 70% precipitation of Fe(III) was apparent in six-week old cultures. Yeast extract (0.2 and 2%) inhibited the bacterial oxidation of pyrite. Incomplete (〜50%) bacterial oxidation of iron dissolved from pyrite was attributed to the inhibition of the bacterial iron-oxidation activity at pH 1.2-1.3. Sample pretreatments with ion-exchange resins before analysis indicated that cationic iron concentration was almost identical with that of total iron in bacterial cultures; anionic forms of Fe amounted to about 7% of the total soluble iron.
