A novel aerobic, psychrotolerant marine bacterium was isolated at 4 °C from seawater samples collected from Spitzbergen in the Arctic. The strain was a polar-flagellated, Gram-negative bacterium that grew optimally at 10–15 °C and pH 7–8 in media containing 2–3 % NaCl (w/v), using various carbohydrates and organic acids as substrates. The main fatty acid components included 16 : 0 (12.7 % of total fatty acids), straight-chain saturated fatty acid methyl ester (FAME) and 16 : 1{omega}7c (40.2 %) monounsaturated FAME. Phylogenetic analysis revealed a close relationship (99 % 16S rRNA gene sequence similarity) between the novel isolate and Pseudoalteromonas elyakovii KMM 162T and some other species of the genus Pseudoalteromonas. The DNA G+C content of the novel strain was 39 mol%. DNA–DNA hybridization showed only 47.6 % DNA–DNA relatedness with P. elyakovii KMM 162T, 44.2 % with Pseudoalteromonas distincta KMM 638T and 22.6 % with Pseudoalteromonas nigrifaciens NCIMB 8614T. Based on phylogenetic and phenotypic characteristics, this isolate represents a novel species of the genus Pseudoalteromonas for which the name Pseudoalteromonas arctica is proposed; the type strain is A 37-1-2T (=LMG 23753T=DSM 18437T).

Abbreviations: FAME, fatty acid methyl ester; AZCL, azurine-crosslinked

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain A 37-1-2T is DQ787199.
