ABSTRACT
A Gram-stain negative, obligately anaerobic, non-motile, asporogenous long rod-shaped and non-flagellated bacterial strain, designated 4SWWS2-6T, was isolated from sediment in the intertidal zone of Fildes Peninsula, Antarctica. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 4SWWS2-6T belongs to the genus Ancylomarina and showed high sequence similarity with Ancylomarina subtilis FA102T (96.5%). Optimal growth occurred at pH 6.5, 16 °C and in the presence of 3% (w/v) NaCl. Strain 4SWWS2-6T contained menaquinone-7 (MK-7) as the major respiratory quinone and held iso-C150, anteiso-C150 and iso-C150 3-OH as the major cellular fatty acids. The major polar lipids were phosphatidylethanolamine, phosphatidylmonomethylethanolamine, an aminolipid, two unidentified lipids and an unidentified phospholipid. The DNA G + C content of strain 4SWWS2-6T was 37.6 mol%. On the basis of the polyphasic analyses, strain 4SWWS2-6T is considered to represent a novel species in the genus Ancylomarina, for which the name Ancylomarina psychrotolerans sp. nov. is proposed. The type strain is 4SWWS2-6T (= KCTC 15504T = MCCC 1K01618T).
