Abstract:
A Gram-stain-positive, aerobic, chemo-organotrophic, rod-shaped, non-spore-forming strain, which produced convex, circular, pink-pigmented colonies, designated as DY32-46 T , was isolated from seawater collected from the Pacific Ocean. DY32-46 T was found to grow at 20–40 °C (optimum, 30–35 °C), pH 6.0–8.0 (optimum, pH 6.5) and with 0–5 % (w/v) NaCl (optimum, 1–2 %). The results of chemotaxonomic analysis indicated that the respiratory quinone of DY32-46 T was MK-9(H 4 ), and major fatty acids ( 〉 10 %) were C 17 : 1 ω 8 c , summed feature 3 (C 16 : 1 ω 7 c and/or C 16 : 1 ω 6 c ), C 16 : 0 and C 15 : 1 ω 6 c . The polar lipids included diphosphatidylglycerol, phosphatidylglycerol, one unidentified aminophospholipid, three unidentified glycolipids, three unidentified phospholipids, one unidentified phosphoglycolipid and five unidentified lipids. The DNA G+C content of DY32-46 T was 70.6 mol%. The results of phylogenetic analysis based on 16S rRNA gene sequences and genomic data indicated that DY32-46 T should be assigned to the genus Euzebya . ANI and in silico DNA–DNA hybridization values between strain DY32-46 T and type strains of Euzebya species were 73.1–87.2 % and 20.2–32.4 %, respectively. Different phenotypic properties, together with genetic distinctiveness, demonstrated that strain DY32-46 T was clearly distinct from recognized species of the genus Euzebya . Therefore, DY32-46 T represents a novel species within the genus Euzebya , for which the name Euzebya pacifica sp. nov is proposed. The type strain is DY32-46 T (=MCCC 1K03476 T =KCTC 49091 T ).
