Acidianus infernus gen. nov., sp. nov., and Acidianus brierleyi Comb. nov.: Facultatively Aerobic, Extremely Acidophilic Thermophilic Sulfur-Metabolizing Archaebacteria

Metallosphaera sedula gen, and sp. nov. Represents a New Genus of Aerobic, Metal-Mobilizing, Thermoacidophilic Archaebacteria

“…Since both organisms exhibited the same GC-content, it became evident that S. brierleyi belonged to the genus Acidianus. It has therefore been transferred to this genus and described as Acidianus brierleyi (Segerer et al, 1986). Two further coccoid isolates were reported to be able to extract metal ions from sulfidic ores at temperatures up to 75 °C (Marsh et al, 1983).…”

Distribution of Complex and Core Lipids within New Hyperthermophilic Members of the Archaea Domain

“…Archaeoglobus represents a biochemical missing link between the methanogens and the sulfur-metabolizing archaea {Achenbach- Richter et al, 1987). Acidianus and its close relative Desulfurolobus represent a missing biochemical link between the sulfur-oxidizing and sulfur-reducing archaea (Segerer et al, 1985;Segerer et al, 1986;Zillig et al, 1986;.…”

Hyperthermophilic Archaea and Bacteria Occurring within Indonesian Hydrothermal Areas

“…From the acidic hot springs and mudholes at.the Dieng Plateau and at Tangkuban Prahu, members of the genus Acidianus were isolated in Allen's medium (Allen, 1959; Table 5). These are chemolithoautotrophic facultative aerobes, growing by oxidation or reduction of elemental sulfur, depending on the redox potential (Segerer et al, 1985;Segerer et al, 1986a). All isolates grow at temperatures of up to 96 °C and are by this feature similar to the type species Acidianus infernas (isolated in Italy).…”
