title: Actibacterium ureilyticum sp. nov., isolated from seawater.
abstract: A polyphasic approach was used to characterize a novel marine bacterial strain, designated LS-811T, isolated from seawater of the South China Sea (Taiwan). Cells of strain LS-811Twere Gram-staining negative, aerobic and rod-shaped with polar flagella. The 16S rRNA gene sequence analysis of strain LS-811T showed highest sequence similarity to Actibacterium mucosum (96.5 %) and Actibacterium atlanticum (95.6 %), and lower sequence similarity (<96.0 %) to members of all other related genera. Strain LS-811Twas able to grow at 15-40 °C and pH 5.0-9.0. The quinone system was ubiquinone (Q-10), and the DNA G+C content was 60.1 mol%. The major fatty acids (>5 %) found in strain LS-811T were C18 : 0, C10 : 0 3-OH, C19 : 0 cyclo ω8c and C18 : 1ω7c/C18 : 1ω6c. The major polar lipid profile consisted of glycolipids, phosphatidylglycerol and one unidentified aminolipid. Based on the distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence analysis, strain LS-811T is considered to represent a novel species in the genus Actibacterium, for which the name Actibacterium ureilyticum sp. nov. is proposed. The type strain is LS-811T (=BCRC 80823T=JCM 30681T).
