Acidophilic and thermophilic Bacillus strains from geothermally heated antarctic soil

Bacteria with temperature optima of 51–54°C and pH optima of 3.5–4.5 were isolated from geothermal soil collected from Mount Erebus, Ross Island, Antarctica. The isolates were enriched on medium designed for the growth of Thermoplasma but the strains found were members of the genus Bacillus . Compar...

Description
Summary:Bacteria with temperature optima of 51–54°C and pH optima of 3.5–4.5 were isolated from geothermal soil collected from Mount Erebus, Ross Island, Antarctica. The isolates were enriched on medium designed for the growth of Thermoplasma but the strains found were members of the genus Bacillus . Comparisons with other thermophilic acidophilic Bacillus species indicate that the strains most strongly resemble B. acidocaldarius although their temperature optima and substrate utilisation spectrum differ from one another. These strains join B. schlegelii as being isolated from geothermal soils present on Mt. Erebus.
