A novel species of Acidimicrobium appeared to be the predominant ferrous iron oxidizer in a mixed culture that effected the continuous, efficient extraction of nickel from a mineral concentrate at 49 degrees C, but it was not isolated in pure culture. It outcompeted Acidimicrobium ferrooxidans, which was expected to have a major role in iron oxidation in reactors gassed with air, and was outnumbered at 49 degrees C only by the sulfur-oxidizing Acidithiobacillus caldus. Sulfobbacillus species were expected to compete with Acidimicrobium species when culture aeration was enriched with carbon dioxide, but they were a minor component of the populations with and without this enrichment. Sulfobacillus thermosulfidooxidans replaced the Acidimicrobium species and Acidithiobacillus caldus when the temperature was increased to 55 degrees C.
