Yoonia

Abstract Yoo'ni.a. N.L. fem. n. Yoonia in honor of Jung‐Hoon Yoon, for his contributions to the taxonomy of marine Alphaproteobacteria . Proteobacteria / Alphaproteobacteria / Rhodobacterales / Rhodobacteraceae / Yoonia Gram‐negative‐staining, aerobic, non‐spore‐forming, and catalase‐ and oxidase‐positive cocci, ovoids, or rods. Optimal growth typically occurs between 25 and 30°C, 0–5% (w/v) NaCl, and pH 6.5–8. Capable of utilizing a large variety of organic carbon compounds. All species tested can utilize acetate and l ‐malate as sole carbon and energy sources. The major fatty acid is C 18:1 ω7 c . The major quinone is ubiquinone 10 (Q‐10). Species have been isolated globally from marine environments such as seawater, marine sediments, and microbial mats. Members of the family Rhodobacteraceae . The type species is Yoonia vestfoldensis . DNA G + C content (mol%) : 53.4–61.8. Type species : Yoonia vestfoldensis Wirth and Whitman 2018 VP ( Loktanella vestfoldensis Van Trappen et al. 2004 VP ).
