| Abstract |
This study presents taxonomic description of strains LB-D12T, AT-3-2T, AT-3-7, and TSA-D2T isolated from Arctic soil. All strains were psychrophilic, Gram-stain-negative, aerobic, non-motile, and rod-shaped. Phylogenetic analysis showed that these strains belonged to the genus Flavobacterium. Strains LB-D12T, AT-3-2T and AT-3-7 were closest to Flavobacterium psychrolimnae LMG 22018T (98.5-98.8% sequence similarity). Strain TSA-D2T was closest to Flavobacterium degerlachei DSM 15718T (98.3 % sequence similarity). These strains shared common chemotaxonomic features comprising MK-6 as a sole quinone, phosphatidylethanolamine as the principal polar lipid, and summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C16 : 0 3-OH, C15 : 1ω6c, iso-C16 : 0, and anteiso-C15 : 0 as the main fatty acids. The ANI and dDDH values between these novel isolates and their closest relatives were below the cut-off values of 95 and 70 %, respectively used for species demarcation. The DNA G+C content of all strains ranged from 34.2 to 34.6 mol%. The obtained polyphasic taxonomic data suggested that the isolated strains represent novel species within the genus Flavobacterium, for which the names Flavobacterium sandaracinum sp. nov. (type strain LB-D12T=KEMB 9005-737T=KACC 21180T=NBRC 113784T), Flavobacterium caseinilyticum sp. nov. (type strain AT-3-2T=KEMB 9005-738T=KACC 21176T=NBRC 113785T), and Flavobacterium hiemivividum sp. nov. (type strain TSA-D2T=KEMB 9005-741T=KACC 21179T=NBRC 113788T) are proposed. |
