- Abstract
- A Gram-stain-negative, yellow-pigmented, strictly aerobic bacterium, designated strain MaA-Y11T, was isolated from a culture of Microcystis aeruginosa in the Republic of Korea. Cells were non-motile rods showing catalase-and oxidase-positive reactions. Growth of strain MaA-Y11T was observed at 25–37 °C (optimum, 30 °C) and pH 6.0–9.0 (optimum, 7.0) and in the presence of 0–1.0% (w/v) NaCl (optimum, 0%). Strain MaA-Y11T did not produce flexirubin-type pigments. Strain MaA-Y11T contained iso-C15:0, iso-C17:0 3-OH and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) as major cellular fatty acids and menaquinone-6 as the sole isoprenoid quinone. Phosphatidylethanolamine, three unidentified aminolipids and four unidentified lipids were detected as the major polar lipids. The G+C content of the genomic DNA was 37.0 mol%. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain MaA-Y11T formed a phyletic lineage with Flavobacterium lindanitolerans IP-10T within the genus Flavobacterium. Strain MaA-Y11T was most closely related to Flavobacterium lindanitolerans IP-10T, with a 98.85% 16S rRNA gene sequence similarity, and shared less than 93.87% sequence similarities with other type strains. Average nucleotide identity and in silico DNA–DNA hybridization values between strain MaA-Y11T and the type strain of F. lindanitolerans were 87.0 and 32.3%, respectively. Here, we conclude that strain MaA-Y11T represents a new species of the genus Flavobacterium, for which the name Flavobacterium microcysteis sp. nov. is proposed. The type strain is MaA-Y11T (=KACC 21225T=JCM 33501T). © 2020 The Authors.
