Description of Lacinutrix salivirga sp. nov., a marine member of the family Flavobacteriaceae isolated from seawater

A novel marine bacterium, designated KMU-57 T , was isolated from seawater collected from the Republic of Korea, and it was characterized using polyphasic taxonomic methods. Strain KMU-57 T was Gram-stain-negative, strictly aerobic, rod-shaped, motile and dark-yellow-pigmented. Comparative analysis based on the 16S rRNA gene sequence showed the affiliation of the isolate with members of the family Flavobacteriaceae of the phylum Bacteroidetes , and it had the greatest sequence similarity (97.6%) to Lacinutrix jangbogonensis PAMC 27137 T . The DNA–DNA relatedness value between strain KMU-57 T and L. jangbogonensis PAMC 27137 T was 37.8 ± 2.2%. The DNA G + C content of strain KMU-57 T was 29.9 mol%; MK-6 was the major menaquinone with; iso-C15:1 G (18.6%) and C16:1 ω 7 c and/or C16:1 ω 6 c (15.8%) as the major (> 10%) cellular fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, three unidentified aminolipids, and five unidentified lipids. The strain represents a novel species of the genus Lacinutrix for which the name Lacinutrix salivirga sp. nov. is proposed. The type strain of L. salivirga sp. nov. is KMU-57 T (= KCTC 52878 T = NBRC 112845 T ).
