Ferrobacillus ferrooxidans was isolated in this laboratory from uranium ores mined at Jaduguda, Bihar. Investigations on a laboratory scale indicated that this organism could leach uranium from ores. Pyruvic acid (10 ‐4 M) was found to inhibit growth of F. ferrooxidans as well as leaching of uranium ore by F. ferrooxidans . However, in the presence of a red pigmented Rhodotorula yeast isolated from the same ores, the pyruvate inhibition was found to be reversed.
