The strain formed orange–red colonies comprising aerobic, Gram-stain-negative, rod-shaped cells on R2A agar. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the organism was closely related to the genus Sporichthya and consistently formed a distinct clade along with the members of this genus. The closest phylogenetic neighbour was Sporichthya polymorpha NBRC 12702T with 93.7 % 16S rRNA gene sequence similarity. The major fatty acids (>10 %) were iso-C16 : 0 (18.7 %), C18 : 1ω9c (18.6 %) and C17 : 1ω8c (14.0 %). The genomic DNA G+C content was 74.4 mol%. The organism contained menaquinone MK-8(H2), MK-9(H4) and an unidentified menaquinone. Polar lipids were composed of phosphatidylglycerol, an unidentified lipid, two unidentified phospholipids and two unidentified aminolipids. The whole-cell sugars contained ribose, xylose, mannose, glucose and galactose. The cell-wall peptidoglycan contained ll-diaminopimelic acid. Based on the physiological, biochemical and chemotaxonomic data, the organism is proposed to represent a novel genus and species, for which the name Longivirga aurantiaca gen. nov., sp. nov. is proposed. The type strain is X5T (=CGMCC 4.7317T=NBRC 112237T).", }
