Four hyerthermophilic isolates of motile, highly irregular archaeal cocci were obtained from the walls of active ''black smokers'' at the Mid-Atlantic Ridge (depth 3500 meters). These obligate anaerobic organisms grew at temperatures between 65 degrees C and 85 degrees C (opatimum 75 to 80 degrees C) at atmospheric pressure. Molecular hydrogen served as electron donor during chemolithoautotrophic growth and H2S was formed from sulfite or thiosulfate. Alternatively, organic acids, glucose, or ethanol were used as electron donors. Sulfate, nitrate, or nitrite could not serve as electron accepters and elemental sulfur inhibited growth. The cells showed a blur-green fluorescence at 436 nm and produced small amounts of methane. One isolate (SNP6) was studied in detail. The G+C content of its DNA was 45 mol%. Based on DNA-DNA hybridization and 16S rDNA sequencing the new isolate was identified as a new species iaa of the genus Archaeoglobus, which is named Archaeglobus veneficus (type strain: SNP6; DSM 11195).
