N2 - Two aerobic, Gram-stain-negative, pale-red-pigmented and rod-shaped bacterial strains, designated SAORIC-26 and SAORIC-28T, were isolated from seawater (3000 m depth) from the Pacific Ocean. Phylogenetic analysis based on their 16S rRNA gene sequences revealed that the novel isolates could be affiliated with the family Rhodothermaceae of the class Cytophagia. Strains SAORIC-26 and SAORIC-28T shared 99.7% pairwise sequence similarity with each other and showed less than 92.6% similarity with other cultivated members of the class Cytophagia. The strains were found to be non-motile, oxidase-positive, catalase-negative and able to hydrolyse gelatin and aesculin. The DNA G+C contents were determined to be 64.8- 65.8 mol% and MK-7 was the predominant menaquinone. Summed feature 9 (iso-C17: 1ω9c and/ or C16: 0 10-methyl), summed feature 3 (C16: 1ω6c and/or C16: 1ω7c) and iso-C15: 0 were found to be the major cellular fatty acids. On the basis of this taxonomic study using a polyphasic approach, it was concluded that strains SAORIC-26 and SAORIC-28T represent a novel species of a new genus in the family Rhodothermaceae, for which the name Rubrivirga marina gen. nov., sp. nov. is proposed. The type strain of the type species of is SAORIC-28T (=KCTC 23867T=NBRC 108816T). An additional strain of the species is SAORIC-26.
