摘要: A Gram-staining-negative, non-pigmented, strictly aerobic, rod-shaped, non-spore-forming, non-motile bacterium, devoid of bacteriochlorophyll, designated strain CC-AMW-ET, was isolated from surface seawater off the coast at Kending, Taiwan. Strain CC-AMW-ET shared 95.7 and 93.9 % 16S rRNA gene sequence similarity, respectively, with type strains species genera Donghicola ( Donghicola eburneus SW-277T) Roseovarius ( Roseovarius tolerans EL-172T). The predominant (>75 % total) fatty acid summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). polar lipid profile included major amounts diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine an unidentified aminolipid. In addition, moderate trace phospholipid were detected. DNA G+C content 67.9 mol%. Ubiquinone Q-10 sole respiratory quinone. Based on its phylogenetic distinctiveness distinguishing phenotypic characteristics (in particular pattern), we conclude that represents a novel genus family Rhodobacteraceae , for which name Youngimonas vesicularis gen. nov., sp. nov. is proposed.
