title: Aureisphaera galaxeae gen. nov., sp. nov., a marine member of the family Flavobacteriaceae isolated from the hard coral Galaxea fascicularis.
abstract: A novel Gram-stain negative, spherical, non-motile, strictly aerobic, heterotrophic, yellow pigmented bacterium, designated strain 04OKA003-7(T) was isolated from the hard coral Galaxea fascicularis L. collected at Akajima, Okinawa, Japan. Phylogenetic analysis based on the 16S rRNA gene sequence revealed the novel isolate is affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (92.9 %) to Vitellibacter aestuarii JC2436(T) and Aureitalea marina S1-66(T). The strain could be differentiated phenotypically from recognized members of the family Flavobacteriaceae. The major fatty acids of strain 04OKA003-7(T) were identified as iso-C15:0 and iso-C17:0 3-OH as defined by the MIDI system. The DNA G+C content was determined to be 41 mol%, the major respiratory quinone was identified as menaquinone 6 (MK-6) and a polar lipid profile was present consisting of phosphatidylethanolamine, two unidentified aminolipids and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Aureisphaera galaxeae gen. nov., sp. nov. is proposed. The type strain of A. galaxeae is 04OKA003-7(T) (=KCTC 32993(T) = NBRC 110018(T)).
