ABSTRACT
A Gram-stain-negative, aerobic, yellow-pigmented, flexirubin-negative, rod-shaped and non-motile bacterial strain, PAMC 28998T, was isolated from a surface sediment sample collected from the Canadian Beaufort Sea. Strain PAMC 28998T grew at 4-37 °C (optimum, 25 °C), at pH 7.0-9.0 (optimum, pH 7.5) and in the presence of 1.0-10.0â% (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain PAMC 28998T belongs to the genus Antarcticibacterium showing the highest sequence similarity (96.8â%) with Antarcticibacterium flavum JB01H24T. The average nucleotide identity and genome-to-genome distance values between PAMC 28998T and the most closely related species (A. flavum JB01H24T) were 74.1 and 18.5â%, respectively, indicating that strain PAMC 28998T is clearly distinguished from A. flavum. The genomic DNA G+C content calculated from genome sequences was 39.8 %. The major fatty acids (>10â%) were iso-C15ââ0 (19.5â%), anteiso-C15ââ0 (18.0â%), iso-C16ââ0 (11.6â%) and summed feature 3 (C161 ω6c and/or C161 ω7c; 11.4â%). The major polar lipids were phosphatidylethanolamine, aminoglycolipid, two unidentified aminolipids, three unidentified phospholipids and four unidentified lipids. The major respiratory quinone was MK-6. Based on the phylogenetic, genomic and phenotypic data presented here, strain PAMC 28998T is considered to represent a novel species of the genus Antarcticibacterium, for which the name Antarcticibacterium arcticum sp. nov. is proposed with the strain PAMC 28998T (=KCCM 43316 T=JCM 33514T).
