- Abstract
A novel Gram-stain-negative bacterium, designated strain BH-SD17T, was isolated from a marine sediment sample in the Bohai Gulf, Yellow Sea, China. Cells of strain BH-SD17T are aerobic, yellow-colored, non-flagellated rods. Growth occurs between 15 and 40 °C (optimum, 30 °C), at pH 6.0–8.5 (optimum, 7.5) and with 1.0–8.0% (w/v) NaCl (optimum, 3.0%). Strain BH-SD17T contains phosphatidylethanolamine and two unidentified lipids as the major polar lipids. The predominant fatty acids are iso-C15:0 (28.5%), iso-C15:1 G (24.4%), and iso-C17:0 3-OH (12.3%). The major respiratory quinone is MK-6. Strain BH-SD17T shows moderate 16S rRNA gene sequence similarity to existing identified strains, is most closely related to the genera Lutimonas (92.1–92.4%), Lutibacter (91.6–92.3%), and Taeania (91.9%). Phylogenetic trees based on 16S rRNA gene sequences show that strain BH-SD17T forms a distinct lineage within the family Flavobacteriaceae. Based on the results of phenotypic, chemotaxonomic and phylogenetic analysis, strain BH-SD17T is considered to represent a novel genus and species in the family Flavobacteriaceae, for which the name Aureibaculum marinum is proposed. The type strain is BH-SD17T (=CCTCC AB 2017072T=KCTC 62204T).
