A Gram-stain-negative, short-rod, aerobic, non-motile, red to pink-pigmented bacterium, designated Fur1T, was isolated from the dry spikelet clusters of a plant called Setaria viridis near Dongguk University. Phylogenetic analysis conducted based on 16S rRNA gene sequences indicated that strain Fur1T belonged to the genus Hymenobacter of the family Hymenobacteraceae. The 16S rRNA gene of Fur1T showed highest sequence similarity to those of Hymenobacter metalli KACC 17381T (97.5 %) and Hymenobacter marinus KACC 19042T (97.1 %). Growth occurred at 4–37 °C (optimum, 25–28 °C), up to 1.0 % NaCl (optimum, 0 %) and pH 5.5–9.0 (optimum, pH 6.0–7.5). The major fatty acids of strain Fur1T were identified as iso-C15 : 0, C16 : 1ω5c, anteiso-C15 : 0, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 4 (comprising anteiso-C17 : 1B and/or iso-C17 : 1I) as the major cellular fatty acids. The predominant respiratory quinone was identified as MK-7. The polar lipids were phosphatidylethanolamine, five unidentified aminophospholipids, two unidentified phospholipids, one unidentified glycolipid and one unidentified polar lipid. The genomic DNA G+C content based on the draft genome sequence was 58.7 mol%. DNA–DNA relatedness between strain Fur1T and its closest relative was below 70 %. Characterization based on phylogenetic, chemotaxonomic and phenotypic analyses clearly indicated that strain Fur1T represents a novel species of the genus Hymenobacter, for which the name Hymenobacter setariae sp. nov. is proposed. The type strain is Fur1T (=KACC 19903T=NBRC=113691T).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
