Phylogenetic analyses based on 16S rRNA gene sequences and an up-to-date bacterial core gene set (92 protein clusters) indicated that strain WWJ-16T is affiliated with the species in the genus Flavobacterium . Strain WWJ-16T was most closely related to Flavobacterium fontis MIC3010T (97.9 % 16S rRNA gene sequence identity) and Flavobacterium squillarum CMJ-5T (97.6 %). Strain WWJ-16T showed 77.4 % average nucleotide identity and 20.6 % digital DNA–DNA hybridization identity with F. fontis MIC3010T. Cells of strain WWJ-16T were Gram-stain-negative, strictly aerobic, non-motile, rod-shaped and formed yellow colonies. Optimal growth occurred at 25 °C, pH 7 and in 0.5–1 % NaCl (w/v). Strain WWJ-16T contained iso-C15 : 1 G and iso-C15 : 0 as predominant fatty acids. The major hydroxyl fatty acids were iso-C15 : 0 3-OH, iso-C17 : 0 3-OH and iso-C16 : 0 3-OH. The polar lipid profile consisted of phosphatidylethanolamine, four uncharacterized aminophospholipids and four uncharacterized phospholipids. The major polyamine was homospermidine. The major isoprenoid quinone was MK-6. The genomic DNA G+C content of strain WWJ-16T was 39.4 mol%, as determined by genome sequencing. The genotypic and phenotypic characteristics indicate that strain WWJ-16T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium stagni sp. nov. is proposed. The type strain is WWJ-16T (=BCRC 81125T =LMG 30600T=KCTC 62515T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003488
