title: Chryseobacterium frigidumsp. nov., isolated from high-Arctic tundra soil, and emended descriptions ofChryseobacterium bernardetiiandChryseobacterium taklimakanense.
abstract: A yellow, Gram-reaction-negative, non-motile, aerobic bacterium, designated D07T, was isolated from a tundra soil near Ny-Ålesund, Svalbard archipelago, Norway (78° N). Growth occurred at 4-37 °C (optimum 28-30 °C) and at pH 6.0-9.0 (optimum pH 7.0-8.0). The strain produced flexirubin-type pigments. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain D07Tbelonged to the genusChryseobacteriumin the familyFlavobacteriaceae. The 16S rRNA gene sequence of this strain showed 93.83 and 93.31 % sequence similarity, respectively, to those ofChryseobacterium contaminansC26TandChryseobacterium taklimakanenseX-65T. Strain D07Tcontained anteiso-C15 : 0(25.91 %), iso-C15 : 0(16.05 %), iso-C16 : 03-OH (9.64 %), iso-C16 : 0(9.42 %) and iso-C14 : 0(7.36 %) as the predominant cellular fatty acids, MK-6 as the major respiratory quinone and phosphatidylethanolamine, five unknown aminolipids and three unknown lipids as the main polar lipids. The DNA G+C content was 49.3 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain D07Tis considered to represent a novel species of the genusChryseobacterium, for which the nameChryseobacterium frigidumsp. nov. is proposed. The type strain is D07T( = CCTCC AB 2011160T= KCTC 42897T). Emended descriptions ofChryseobacterium bernardetiiandChryseobacterium taklimakanenseare also provided.
