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 D07T belonged to the genus Chryseobacterium in the family Flavobacteriaceae. The 16S rRNA gene sequence of this strain showed 93.83 and 93.31 % sequence similarity, respectively, to those of Chryseobacterium contaminans C26T and Chryseobacterium taklimakanense X-65T. Strain D07T contained anteiso-C15 : 0 (25.91 %), iso-C15 : 0 (16.05 %), iso-C16 : 0 3-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 D07T is considered to represent a novel species of the genus Chryseobacterium, for which the name Chryseobacterium frigidum sp. nov. is proposed. The type strain is D07T ( = CCTCC AB 2011160T = KCTC 42897T). Emended descriptions of Chryseobacterium bernardetii and Chryseobacterium taklimakanense are also provided., language=, type=
