title: Arcticibacter eurypsychrophilus sp. nov., isolated from ice core.
abstract: A Gram-stain-negative, rod-shaped, non-flagellated bacterium, strain MJ9-5(T), was isolated from ice core of Muji Glacier. Colonies of strain MJ9-5(T) were pink, convex and round on R2A agar. Strain MJ9-5(T) grew between -1 to 25 °C with an optimum growth temperature of 10-15 °C. The strain tolerated 0-1.2 % (w/v) NaCl with an optimum of 1 %. The major cellular fatty acids of strain MJ9-5(T) were iso-C15 : 0, summed feature 3 (C16 : 1ω6c and/or C1 6 : 1ω7c). The G+C content of the genomic DNA was 38.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ9-5(T) was related to members of the genus Arcticibacter. On the basis of the phenotypic characteristics and phylogenetic analysis, a novel species of this genus, Arcticibacter eurypsychrophilus sp. nov., is proposed. The type strain is MJ9-5(T) ( = KCTC 42008(T) = JCM 19862(T)).
