title: Psychroserpens jangbogonensis sp. nov., a psychrophilic bacterium isolated from Antarctic marine sediment.
abstract: A Gram-staining-negative, yellow-pigmented, aerobic, rod-shaped and non-motile bacterium, PAMC 27130(T), was isolated from the marine sediment of the Ross Sea, Antarctica. The temperature, pH and NaCl tolerance ranges for growth were 4-20 °C, pH 6.0-9.0 and 0.5-5.0 % (w/v) NaCl, respectively. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain PAMC 27130(T) belonged to the genus Psychroserpens and was closely related to Psychroserpens mesophilus, Psychroserpens damuponensis and Psychroserpens burtonensis with 97.2, 94.7 and 94.2 % sequence similarities, respectively. Genomic relatedness analyses based on average nucleotide identity and genome-to-genome distance showed that strain PAMC 27130(T) could be clearly distinguished from other species of the genus Psychroserpens . The genomic DNA G+C content was 32.7 mol%. The major fatty acids (>10 %) were C20 : 4ω6c (13.2 %), iso-C15 : 0 (12.3 %), iso-C15 : 1 G (11.7 %) and iso-C15 : 0 3-OH (10.0 %). The major respiratory isoprenoid quinone was menaquinone-6 (MK-6) and the polar lipids were phosphatidylethanolamine, two unidentified aminolipids, an unidentified phospholipid, an unidentified aminophospholipid and three unidentified lipids. On the basis of genotypic and phenotypic data collected in this study, it is proposed that strain PAMC 27130(T) represents a novel species of the genus Psychroserpens, for which the name Psychroserpens jangbogonensis sp. nov. is proposed. The type strain is PAMC 27130(T) ( = KCTC 42128(T) = JCM 30228(T)).
