<i>Oxyplasma meridianum</i> gen. nov., sp. nov., an extremely acidophilic organotrophic member of the order <i>Thermoplasmatales</i>.

ABSTRACT: A mesophilic, hyperacidophilic archaeon, strain M1^T, was isolated from a rock sample from Vulcano Island, Italy. Cells of this organism were cocci with an average diameter of 1 µm. Some cells possessed filaments. The strain grew in the range of temperatures between 15 and 52 °C and pH 0.5-4.0 with growth optima at 40 °C and pH 1.0. Strain M1^T was aerobic and chemoorganotrophic, growing on complex substrates, such as casamino acids, trypticase, tryptone, yeast and beef extracts. No growth at expenses of oxidation of elemental sulphur or reduced sulphur compounds, pyrite, or ferrous sulphate was observed. The core lipids were glycerol dibiphytanyl glycerol tetraether lipids (membrane spanning) with 0 to 4 cyclopentane moieties and archaeol, with trace amounts of hydroxy
