sp. nov., isolated from Arctic marine sediment Free

Abstract

A Gram-negative, non-motile, aerobic bacterium, designated strain KOPRI 20941, was isolated from a sample of marine sediment from Ny Ålesund, Spitsbergen, Norway. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the Arctic isolate nested within the genus and showed the highest sequence similarity (98.1 %) with respect to KMM 3947. Chemotaxonomic data (DNA G+C content of 36 mol%; MK-6 as the major respiratory quinone and iso-C 3-OH, C 7/iso-C 2-OH and iso-C as the major fatty acids) supported the affiliation of strain KOPRI 20941 to the genus . The results of phylogenetic analyses, physiological and biochemical tests and a DNA–DNA reassociation test (<54 % relatedness) allowed genotypic and phenotypic differentiation of the strain from the recognized species of the genus . Therefore strain KOPRI 20941 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KOPRI 20941 (=KCTC 22053=JCM 14790).
