title: Sediminivirga luteolagen. nov., sp. nov., a member of the familyBrevibacteriaceae, isolated from marine sediment.
abstract: A Gram-stain-positive actinobacterial strain, designated F23T, was isolated from marine sediment collected from the western Pacific. Strain F23Tshowed less than 94.5 % 16S rRNA gene sequence similarity with type strains of species with validly published names. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that the novel isolate formed a distinct monophyletic clade within the familyBrevibacteriaceaeand clustered distantly with the generaBrevibacteriumandSpelaeicoccus. Cells of strain F23Twere non-motile, rod-shaped and aerobic to microaerophilic. Optimal growth occurred at 35-37 °C, at pH 8.0-9.0 and in the presence of 1 % NaCl (w/v). The isolate containedmeso-diaminopimelic acid as the characteristic cell-wall diamino acid, MK-8(H2) and MK-7(H2) as the predominant menaquinones and anteiso-C15 : 0and anteiso-C17 : 0as the major fatty acids. The DNA G+C content of strain F23Twas 69.0 mol%. On the basis of phylogenetic analysis, phenotypic and chemotaxonomic characteristics and 16S rRNA gene signature nucleotide patterns, strain F23Trepresents a novel species in a novel genus in the familyBrevibacteriaceae, for which the nameSediminivirga luteolagen. nov., sp. nov. is proposed. The type strain is F23T( = JCM 19771T= CGMCC 1.12785T= MCCC 1A09945T).
