title: Lacinutrix gracilariaesp. nov., isolated from the surface of a marine red algaGracilariasp.
abstract: A Gram-stain-negative, aerobic, non-flagellated, rod-shaped bacterium, designated strain Lxc1T, was isolated from the surface of a marine red alga,Gracilariasp., which was collected from the coastal regions in Jinjiang, Fujian Province, China. Colonies of the strain were orange-yellow, circular and smooth. The 16S rRNA gene of strain Lxc1Thad maximum sequence similarity withLacinutrix himadriensisE4-9aT(97.1 %), followed byLacinutrix jangbogonensisPAMC 27137T,Lacinutrix copepodicolaDJ3T,Lacinutrix algicolaAKS293TandLacinutrix mariniflavaAKS 432T(similarities < 96.4 %). Phylogenetic analysis showed strain Lxc1Tformed a tight cluster withL. himadriensisE4-9aTandL. copepodicolaDJ3T, but represented a novel lineage belonging to the genusLacinutrix. The predominant fatty acids were iso-C15 : 1G (18.3 %), iso-C15 : 0(16.7 %), iso-C17 : 03-OH (10.6 %) and iso-C15 : 03-OH (8.6 %). Menaquinone-6 (MK-6) was the only respiratory quinone present. The DNA G+C content of strain Lxc1Twas 31.7 mol%. Combining the results above, it was ascertained that strain Lxc1Trepresented a novel species of the genusLacinutrix, for which the nameLacinutrix gracilariaesp. nov. is proposed. The type strain is Lxc1T( = MCCC 1A01567T= KCTC 42808T).
