| Abstract |
A Gram-stain-negative, aerobic, catalase- and oxidase-positive, rod-shaped, flagellated bacterial strain, designated AMac2203T, was isolated from the gut of the cinereous vulture, Aegypiusmonachus, collected from the Seoul Grand Park Zoo, Republic of Korea. Strain AMac2203T grew optimally at 15-25 °C, pH 7-8 and in the presence of 3-5 % (w/v) NaCl. Phylogenetic analysis revealed 97.4-97.9 % and 96.9-97.3 % sequence similarities of the 16S rRNA genes to its counterparts in Oceanisphaera profunda SM1222T and Oceanisphaera ostreae T-w6T, respectively. The predominant fatty acids (>10 %) of strain AMac2203T were summed feature 3 (C16 : 0ω7c and/or C16 : 1ω6c, 33.6 %), summed feature 8 (C18 : 1ω7c, 24.5 %) and C16 : 0 (19.9 %). The primary isoprenoid quinone was ubiquinone-8. Polar lipids included phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified amino lipid and an unidentified lipid. Based on complete genome sequencing of strain AMac2203T and the closest related type strain, O. profunda, the OrthoANI value is 77.5 %, which is below the 95 % cut-off for species demarcation. The genomic DNA G+C content of strain AMac2203T is 47.1 mol%. Thus, strain AMac2203T represents a novel species candidate of the genus Oceanisphaera. We propose the name Oceanisphaeraavium sp. nov., with strain AMac2203T (=KCTC 62118T=JCM 32207T) as the type strain.
