Abstract 

A Gram-stain-positive, facultatively anaerobic, non-spore-forming, non-flagellated and rod-shaped or ovoid bacterial strain, designated BS-12MT, was isolated from a tidal flat sediment on the South Sea, South Korea. Strain BS-12MT grew optimally at 35 °C, at pH 7.0?8.0 and in the presence of 2.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain BS-12MT fell within the cluster comprising the type strains of species of the genus Demequina, joining the type strain of Demequina aestuarii with which it shared the highest sequence similarity (98.6 %). It exhibited 16S rRNA gene sequence similarity of 96.1?97.9 % to the type strains of other species of the genus Demequina. The peptidoglycan type of strain BS-12MT was A4β based on L-Orn ? L-Ser ? D-Glu. Strain BS-12MT contained demethylmenaquinone-9(H4) as the major menaquinone and anteiso-C15:0 and C16:0 as the major fatty acids. The major polar lipids of strain BS-12MT were phosphatidylinositol and phosphatidylinositolmannoside. The DNA G+C content of strain BS-12MT was 70.7 mol% and its DNA?DNA relatedness values with the type strains of five phylogenetically related species of the genus Demequina were 15?34 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain BS-12MT is separate from other species of the genus Demequina. On the basis of the data presented, strain BS-12MT is considered to represent a novel species of the genus Demequina, for which the name Demequina activiva sp. nov. is proposed. The type strain is BS-12MT (= KCTC 29674T = NBRC 110675T ).
