title: Sediminibacterium salmoneum gen. nov., sp. nov., a member of the phylum Bacteroidetes isolated from sediment of a eutrophic reservoir.
abstract: Strain NJ-44(T), isolated from sediment of the eutrophic Guanting Reservoir in Beijing (China), was subjected to a taxonomic study using a polyphasic approach. The strain was aerobic, with salmon-pink-pigmented colonies on R2A agar. Cells were single, Gram-negative rods, motile by gliding. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain NJ-44(T) belonged to the phylum Bacteroidetes, with Terrimonas ferruginea ATCC 13524(T) (90.8% similarity), Terrimonas lutea DY(T) (90.5%) and Niabella aurantiaca R2A15-11(T) (89.1%) as its closest relatives. Strain NJ-44(T) was clearly differentiated from members of the genera Terrimonas and Niabella in its DNA G+C content (40.6 mol%) and its major fatty acids, iso-C(15:1) G, iso-C(15:0), anteiso-C(15:0), iso-C(16:0) 3-OH, iso-C(17:0) 3-OH, anteiso-C(15:1) A and iso-C(15:0) 3-OH. It is proposed that strain NJ-44(T) represents a novel genus and species, named Sediminibacterium salmoneum gen. nov., sp. nov. The type strain of Sediminibacterium salmoneum is strain NJ-44(T) (=CGMCC 1.6845(T) =NBRC 103935(T)).
