A yellow-pigmented bacterial strain, designated M1-33108T, was isolated from the till of high Arctic glacier Midtre Lovénbreen near Ny-Ålesund, in the West Svalbard Archipelago, Norway. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain M1-33108T belonged to the genus Terrimonas and its closest neighbour was Terrimonas arctica R9-86T with 96.12 % 16S rRNA gene sequence similarity. Cells of strain M1-33108T were Gram-reaction-negative, aerobic, non-spore-forming, rod-shaped bacteria that lacked motility. Cells contained iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) as its major cellular fatty acids and menaquinone-7 as the sole respiratory quinone. The polar lipid profile of strain M1-33108T consisted of phosphatidylethanolamine, two unknown aminophospholipids, eight unknown aminolipids, an unknown glycolipid and three unknown polar lipids. The DNA G+C content was 45.0 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain M1-33108T is considered to represent a novel species in the genus Terrimonas, for which the name Terrimonas crocea sp. nov. is proposed. The type strain is M1-33108T (=CCTCC AB 2016103T=KCTC 52448T).
