Abstract

A Gram-negative, rod-shaped, psychrophilic, motile, non-spore-forming bacterium, strain U1, was isolated from Ushuaia located at the southernmost tip of Argentina. On the basis of 16S rRNA gene sequence similarity, strain U1 was found to be closely related to (DSM 5604) and (IAM 15010). At the DNA–DNA level, however, the values for similarity were 41 and 25 %, respectively. The major fatty acids present were iso-C, C 7, iso-C and C 7 and the G+C content of the DNA was 43·6 mol%. All of the above characteristics support the affiliation of strain U1 to the genus . Furthermore, on the basis of phenotypic features, chemotaxonomic characteristics and phylogenetic analysis of the 16S rRNA gene sequence, it appears that strain U1 is distinct from the four species with validly published names. Strain U1, therefore, represents a novel species, for which the name sp. nov. is proposed. The type strain of is U1 (=MTCC 6143=DSM 15871=JCM 12170).
