Abstract

A Gram-negative, orange-colony-forming, aerobic and non-flagellated bacterium, designated strain SM1202, was isolated from marine sediment of Kongsfjorden, Svalbard. Analysis of 16S rRNA gene sequences revealed that strain SM1202 was phylogenetically closely related to the genus . It shared the highest 16S rRNA gene sequence similarity with the type strain of (94.2 %) and 92.7–93.9 % sequence similarity with type strains of other known species of the genus . The strain grew at 4–35 °C and with 1.0–5.0 % (w/v) NaCl. It contained iso-C, iso-C 3-OH, iso-C, C, iso-C G, iso-C 3-OH and Cω6 as predominant cellular fatty acids and menaquinone-6 (MK-6) as the major respiratory quinone. The polar lipids of strain SM1202 were phosphatidylethanolamine, one unidentified lipid, two unidentified aminophospholipids and one unidentified aminolipid. The genomic DNA G+C content of strain SM1202 was 36.4 mol%. On the basis of the data from this polyphasic taxonomic study, strain SM1202 represents a novel species in the genus of the family , for which the name sp. nov. is proposed. The type strain of is SM1202 ( = CCTCC AB 2013148 = KCTC 32516). An emended description of the genus is also presented.
