title: Thalassiella azotovora gen. nov., sp. nov., a New Member of the Family Kineosporiaceae Isolated from Sea Water in South Korea.
abstract: A gram-positive, nonmotile, rod-shaped, nonflagellated, aerobic bacterium, designated strain DSD2(T) was isolated from a seawater sample from Sadong wharf, Ulleung-Island, South Korea. Strain DSD2(T) was found to be able to grow at pH ranging from 6 to 11 (optimum 7-8), 0-7 % (w/v) NaCl (optimum 0 %), at 10-42 °C (optimum 37 °C). 16S rRNA gene sequence analysis revealed that strain DSD2(T) was 95.8 % similar to the type strain of Kineosporia rhamnosa KACC 15195(T), 95.8 % similar to Angustibacter aerolatus KACC 15527(T), and 95.5 % similar to Kineococcus xinjiangensis KCTC 19474(T) as its closest relatives. A neighbor-joining phylogenetic tree based on the 16S rRNA gene sequence showed that strain DSD2(T) related to Micrococcineae and Kineosporiineae suborder clade. The major polar lipids were phosphoglycolipids and phospholipids. Strain DSD2(T) was found to contain MK-8 (H2) and MK-9 (H4) as the predominant menaquinone and iso-C16:0 as the major fatty acid. The isolate contained meso-diaminopimelic acid (meso-A2pm) with alanine, glutamic acid, and glycine as the diagnostic diamino acid. The DNA G+C content of strain DSD2(T) was 73.2 mol%. On the basis of phylogenetic, biochemical, chemotaxonomic, and other physiological characteristics, strain DSD2(T) is assigned to a novel species of a novel genus within the suborder Kineosporiineae and the name Thalassiella azotovora gen nov., sp. nov., is proposed. The type strain is DSD2(T) (= KCTC 39634(T) = JCM 31134(T)).
