Strain NJ-44, 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 belonged to the phylum , with ATCC 13524 (90.8 % similarity), DY (90.5 %) and R2A15-11 (89.1 %) as its closest relatives. Strain NJ-44 was clearly differentiated from members of the genera and in its DNA G+C content (40.6 mol%) and its major fatty acids, iso-C G, iso-C, anteiso-C, iso-C 3-OH, iso-C 3-OH, anteiso-C A and iso-C 3-OH. It is proposed that strain NJ-44 represents a novel genus and species, named gen. nov., sp. nov. The type strain of is strain NJ-44 (=CGMCC 1.6845 =NBRC 103935).
