Abstract

A Gram-stain-negative, aerobic, catalase- and oxidase-positive, rod-shaped, flagellated bacterial strain, designated AMac2203, was isolated from the gut of the cinereous vulture, , collected from the Seoul Grand Park Zoo, Republic of Korea. Strain AMac2203 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 SM1222 and T-w6, respectively. The predominant fatty acids (>10 %) of strain AMac2203 were summed feature 3 (C 7 and/or C 6, 33.6 %), summed feature 8 (C 7, 24.5 %) and C (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 AMac2203 and the closest related type strain, , the OrthoANI value is 77.5 %, which is below the 95 % cut-off for species demarcation. The genomic DNA G+C content of strain AMac2203 is 47.1 mol%. Thus, strain AMac2203 represents a novel species candidate of the genus . We propose the name sp. nov., with strain AMac2203 (=KCTC 62118=JCM 32207) as the type strain.
