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 omega 7c and/or C16:1 omega 6c (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)).
