Several strains of a novel heterotrophic gas vacuolate bacterium were isolated from antarctic marine waters. The results of phylogenetic analyses in which 16S ribosomal DAN sequencing was used, coupled with phenotypic tests, indicated that strain 34-P(T) (T = type strain) belongs to a new genus and species of the beta subgroup of the Proteobacteria, for which the name Polaromonas vacuolata is proposed. Although the other four strains studied probably belong to this new species, DNA-DNA hybridization tests were not conducted. The closest phylogenetic relatives of P. vacuolata are the photosynthetic nonsulfur purple bacterium Rhodoferax fermentans and the hydrogen autotroph Variovorax paradoxus.
