A Gram-stain-positive, facultatively aerobic, spore-forming, oxidase-positive, catalase- and DNase-negative, rod-shaped and motile bacterial strain, AR23208T, was isolated from the gut of a cinereous vulture (Aegypius monachus), collected at Seoul Grand Park Zoo (Republic of Korea). Strain AR23208T grew optimally at 25-30 °C, at pH 7 and in the absence of NaCl. Phylogenetic analysis revealed that strain AR23208T shared 98.2 and 97.1 % 16S rRNA gene sequence similarity with Tumebacillus algifaecis THMBR28T and Tumebacilluslipolyticus NIO-S10T, respectively. The predominant fatty acids (>10 %) of strain AR23208T were iso-C15 : 0, summed feature 4 (anteiso-C17 : 1 B and/or iso-C17 : 1 I) and anteiso-C15 : 0 and the primary isoprenoid quinone was menaquinone-7. The polar lipids were phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylglycerol, six unidentified phospholipids, an unidentified aminophospholipid and ten unidentified lipids. The sugar components of the cell wall peptidoglycan were ribose and arabinose. The amino acids of the cell wall peptidoglycan were l-alanine, aspartic acid, meso-diaminopimelic acid, l-glutamic acid, glycine and l-lysine. The OrthoANI value based on the complete genome sequence of strain AR23208T and the closest related strain, T. algifaecis THMBR28T, was 80.4 %. The genomic DNA G+C content of strain AR23208T was 56.0 mol%. Based on the data presented in the current study, strain AR23208T is considered to represent a novel species of the genus Tumebacillus, for which the name Tumebacillus avium sp. nov. is proposed. The type strain is AR23208T (=KCTC 33929T=JCM 32188T).
