  • Two Gram-stain-negative, non-spore-forming, rod-shaped, aerobic and yellow-coloured bacterial strains, designated strains ECD14 and EC2D5, were isolated from a seaweed Eckloniacava. The isolates required sea salts for growth. Flexirubin-type and carotenoid pigment was produced. The 16S rRNA gene sequence similarity between the two new strains was 95.5 %. Flavivirga amylovorans JC2681 was the nearest neighbour of strains ECD14 and EC2D5 with 96.5 and 96.8 % 16S rRNA gene sequence similarity, respectively. The common major fatty acids and respiratory quinones were iso-C15 : 0, iso-C15 : 1 G and unknown 13.565 and menaquinone 6 (MK-6), respectively. The common major polar lipids were phosphatidylethanolamine, an unknown amino lipid and an unknown lipid. The DNA G+C contents of strains ECD14 and EC2D5 were 33 and 31 mol%, respectively. On the basis of the polyphasic characterization of the two strains, it is suggested that the two isolates represent novel species of the genus Flavivirga , for which the names Flavivirga eckloniae sp. nov. (type strain, ECD14=KCTC 52352=JCM 31797) and Flavivirga aquimarina sp. nov. (type strain, EC2D5=KCTC 52353=JCM 31796) are proposed.

  • The GenBank accession numbers for the 16S rRNA gene sequences of strain ECD14 (=KCTC 52352=JCM 31797) and strain EC2D5 (=KCTC 52353=JCM 31796) are KU725769 and KX245374, respectively.

  • Three supplementary figures are available with the online Supplementary Material.
