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 : 1ω7c and/or C16 : 1ω6c) 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 nucl...
