sp. nov., a psychrophilic bacterium from the McMurdo Dry Valleys, Antarctica Free

Abstract

A novel psychrophilic bacterium, designated strain DVS 3Y, was isolated from a moraine sample from the McMurdo Dry Valleys, Antarctica. Phenotypic and chemotaxonomic characteristics and data from a phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DVS 3Y was related to the genus . Strain DVS 3Y exhibited >97 % gene sequence similarity with respect to DSM 20416 (97.4 %), DSM 17272 (97.4 %), IAM 15368 (97.6 %), DSM 14481 (98.2 %), DSM 17290 (98.6 %) and DSM 14480 (99.6 %). However, the levels of DNA–DNA relatedness between strain DVS 3Y and DSM 20416, JCM 12280, IAM 15368, DSM 14481, DSM 17290 and DSM 14480 were less than 70 % (52, 25, 16, 33, 16 and 38 %, respectively). Strain DVS 3Y also differed from these six closely related species in a number of phenotypic traits. Phenotypic, chemotaxonomic and phylogenetic data suggest that strain DVS 3Y represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DVS 3Y (=MTCC 4816=JCM 14376).
