Sediminibacterium salmoneum gen. nov., sp nov., a member of the phylum Bacteroidetes isolated from sediment of a eutrophic reservoir

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 DYT (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)).
