title: Branchiibius hedensis gen. nov., sp. nov., an actinobacterium isolated from a Japanese codling (Physiculus japonicus).
abstract: A novel, Gram-stain-positive bacterial strain, Mer 29717(T), was isolated from the branchia (gills) of a Japanese codling, Physiculus japonicus, collected from bottom waters of Suruga Bay in Shizuoka, Japan. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain represents a distinct lineage within the family Dermacoccaceae and was related most closely to members of the genera Demetria and Yimella. It shared highest 16S rRNA gene sequence similarity (95.1 %) with Yimella lutea YIM 45900(T). Strain Mer 29717(T) contained MK-8(H(2)) and MK-8(H(4)) as menaquinones, and iso-C(16 : 0), C(16 : 0), C(17 : 1) cis-9, C(17 : 0), C(18 : 1) cis-9 and C(19 : 1) cis-10 were the major cellular fatty acids. The cell-wall peptidoglycan of strain Mer 29717(T) was composed of l-Lys, d-Ser, l-Ser, Gly, d-Glu and d-Ala. Polar lipids were phosphatidylinositol, phosphatidylglycerol, diphosphatidylglycerol and one unidentified phospholipid. Mycolic acids were not detected. The G+C content of the DNA of strain Mer 29717(T) was 68 mol%. On the basis of differential chemotaxonomic, physiological and biochemical data, strain Mer 29717(T) is considered to represent a novel species of a new genus, for which the name Branchiibius hedensis gen. nov., sp. nov. is proposed. The type strain of Branchiibius hedensis is Mer 29717(T) ( = NBRC 106121(T)  = DSM 22951(T)).
