A novel, strictly aerobic, red-pigmented, Gram-reaction-negative bacterium, designated strain R9-9(T), was isolated from tundra soil collected near Ny-Alesund, Svalbard Archipelago, Norway (78 degrees N). The novel strain was subjected to a taxonomic study using a polyphasic approach. It grew optimally at 20-22 degrees C and at pH 7.0. Flexirubin-type pigments were absent. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain R9-9(T) represents a distinct phyletic line that reflects a novel generic status within the family Cytophagaceae. The novel strain showed relatively low 16S rRNA gene sequence similarities (<88.0%) to members of established genera. Strain R9-9(T) contained summed feature 3 (C-(16:1)omega 7c and/or C-16:1 omega 6C), iso-C-17:0 3-OH, iso-C-(15:0) and C-16:1 omega 5c as its major cellular fatty acids, phosphatidylethanolamine as its main polar lipid, and MK-7 as its major respiratory quinone. The genomic DNA G+C content was 56.1 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain R9-9(T) is considered to represent a novel species in a new genus in the family Cytophagaceae, for which the name Huanghella arctica gen. nov., sp. nov. is proposed. The type strain is R9-9(T) (=CCTCC AB 2010418(T)=NRRL B-59750(T)).
