Abstract
A novel Gram-stain-positive, non-motile, non-spore-forming, coccobacillus-shaped, strictly aerobic bacterium, designated strain H23T48T, was isolated from the faecal sample of an oriental stork collected from the Seoul Grand Park Zoo in Seoul, Republic of Korea. Optimal growth of strain H23T48T was observed at 30–37 °C, pH 8 and with 3 % (w/v) NaCl. 16S rRNA gene sequence-based phylogenetic analysis revealed that strain H23T48T was closely related to the genus Flaviflexus , with 97.0 and 96.7 % sequence similarities to Flaviflexus salsibiostraticola EBR4-1-2T and Flaviflexus huanghaiensis H5T, respectively. Strain H23T48T possessed MK-9(H4) as the major menaquinone and C16 : 0 (42.4 %), C18 : 1 ω9c (31.3 %) and C14 : 0 (17.7 %) as the major cellular fatty acids. The polar lipids included phosphatidylglycerol, two unidentified lipids, six unidentified phospholipids and two unidentified glycophospholipids. The amino acid composition of the cell-wall peptidoglycan was l-alanine, l-lysine, d-glutamic acid, l-aspartic acid and glycine. The genomic G+C content of strain H23T48T is 59.5 mol% and the average nucleotide identity value between H23T48T and F. salsibiostraticola KCT C33148T (=EBR4-1-2T) is 75.5 %. Based on the obtained data, strain H23T48T represents a novel species of the genus Flaviflexus , for which the name Flaviflexus ciconiae sp. nov. is proposed. The type strain is H23T48T (=KCTC 49253T=JCM 33282T).
