| Abstract |
A novel Gram-stain-negative, facultatively anaerobic, non-motile, non-violet-pigmented, rod-shaped bacterium, designated strain H11R3T, was isolated from the feces of Oriental stork, Ciconia boyciana, collected from Seoul Grand Park Zoo, Republic of Korea. Phylogenetic analysis of the 16S rRNA gene sequence revealed that H11R3T formed a monophyletic clade with Iodobacter fluviatilisDSM 3764T, Iodobacter arcticusDSM 100243T, and Iodobacter limnosediminisDSM 103822T, with sequence similarities of 98.8, 98.6 and 98.4 %, respectively. H11R3T grew optimally at 15 °C, pH 8, with 0.5 % (w/v) NaCl. The predominant isoprenoid quinone was ubiquinone-8 (Q-8), and polar lipids included phosphatidylethanolamine, three unidentified lipids, four unidentified phospholipids, and two unidentified aminophospholipids. The major fatty acids were summed feature 3 and C16 : 0, and the DNA G+C content of the genome is 48.0 mol%. The average nucleotide identity (ANI) value between strains H11R3T and I. fluviatilis NCTC 11159T (=DSM 3764T) is 83.7 %. On the basis of phenotypic, genotypic, phylogenetic and chemotaxonomic characteristics, strain H11R3T represents a novel species of the genus Iodobacter for which the name Iodobacterciconiae sp. nov. is proposed. The type strain is H11R3T (=KCTC 62666T=JCM 33283T).
