Abstract

A Gram-stain-negative, non-spore-forming, motile, strictly aerobic bacterial strain, designated CAU 1294, was isolated from a sand sample and its taxonomic position was investigated using a polyphasic approach. The strain grew optimally at pH 6.5 and 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU 1294 formed a lineage with member of the genus and exhibited similarity to MKT133 (96.3 % similarity) and LMG 23452 (95.1 % similarity). Strain CAU 1294 contained Q-10 as the predominant respiratory quinone. Cω7, C and cyclo-Cω8 were the major cellular fatty acids. The polar lipids were composed of phosphatidylethanolamine, phosphatidylmethylethanolamine and two unidentified phospholipids. The DNA G+C content was 56.6 mol%. On the basis of these results, strain CAU 1294 is considered to represent a novel species of the genus , for which the name is proposed. The type strain is CAU 1294 ( = KCTC 32476 = CECT 8513). An emended description of the genus is also proposed.
