Characteristics of Sulfobacillus acidophilus sp. nov. and other moderately thermophilic mineral-sulphide-oxidizing bacteria
Article Abstract:
Isolates of Gram-positive, acidophilic, moderately thermophilic, ferrous-iron- and mineral-sulphide-oxidizing bacteria were studied to determine the characteristics of Sulfobacillus-like bacteria. Sulfobacillus thermosulfidooxidans and Sulfobacillus acidophilus grew autotropically and mixotropically on ferrous iron, on elemental sulphur in the presence of yeast extract, and heterotropically on yeast extract. Autotrophic growth on sulphur was always observed with S. acidophilus.

Acidimicrobium ferrooxidans gen. nov., sp. nov.: mixed-culture ferrous iron oxidation with Sulfobacillus species
Article Abstract:
A new species of ferrous-iron-oxidizing, moderately thermophilic, acidophilic bacteria, Acidimicrobium ferrooxidans, has been discovered. This species has greater capacity to fix CO2 from air than the iron-oxidizing thermoacidophiles of the genus Sulfobacillus. The ferrous oxidation in mixed cultures of A. ferrooxidans with either Sulfobacillus thermosulfooxidans or Sulfobacillus acidophilus was more extensive under air than in pure cultures of these three strains.

A novel Acidimicrobium species in continuous cultures of moderately thermophilic, mineral-sulfide-oxidizing acidophiles
Article Abstract:
The role of Acidimicrobium as a ferrous iron oxidizer is discussed. Results suggest that Acidimicrobium is the predominant ferrous iron oxidizer in a mixed culture affecting the continuous, efficient extraction of nickel from a mineral concentrate at 49 degree Celsius.
