A novel moderately thermophilic, organotrophic, microaerophilic, facultatively chemolithotrophic bacterium, designated strain 506^T, was isolated from a deep-sea hydrothermal vent site at 13°N in the East Pacific Rise. Cells were Gram-negative, non-motile rods. The organism grew in the temperature range 40–68 °C, with an optimum at 60 °C, and in the pH range 5·5–8·4, with an optimum around pH 7·5. The NaCl concentration for growth was in the range 10–50 g l^-1, with an optimum at 30 g l^-1. Strain 506^T grew chemoorganoheterotrophically with carbohydrates, proteinaceous substrates, organic acids and alcohols using oxygen or nitrate as electron acceptor. Alternatively, strain 506^T was able to grow lithoheterotrophically with molecular hydrogen as the energy source. The G+C content of the genomic DNA was 62·9 mol%. Phylogenetic analysis of the 16S rDNA sequence placed strain 506^T in the family Thermaceae. On the basis of phenotypic and phylogenetic data, strain 506^T (=DSM 14977^T=VKM B-2274^T) is proposed as the type strain of a novel species in a new genus, Oceanithermus profundus gen. nov., sp. nov.

The GenBank accession number for the 16S rRNA gene sequence of strain 506^T is AJ430586.
