Abstract: A novel moderately thermophilic, organotrophic, microaerophilic, facultatively chemolithotrophic bacterium, designated strain 506(T), was isolated from a deep-sea hydrothermal vent site at 13 degrees N in the East Pacific Rise. Cells were Gram-negative, non-motile rods. The organism grew in the temperature range 40-68 degrees C, with an optimum at 60 degrees 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.
