A bacterium capable of growth from 59 to 72° C was isolated from geothermal soil collected from Mount Erebus, Ross Island, Antarctica. The isolate was enriched in medium containing thiosulphate and bicarbonate. Subsequently the organism was found also to be capable of heterotrophic growth and autotrophic growth in the presence of hydrogen and carbon dioxide. In a comparison with Bacillus schlegelii and Bacillus tusciae the isolate most closely resembled B. schlegelii. This conclusion was supported by the finding that B. schlegelii is also capable of autotrophic growth using thiosulphate. The new isolate had a characteristic subunit layer on the cell wall which is typical of B. schlegelii.
