Abstract Bi.zi.o'ni.a. N.L. fem. n. Bizionia , named in honor of the famous Italian naturalist Bartolomeo Bizio, for his important contribution to the development of microbiology. Bacteroidetes / Flavobacteriia / Flavobacteriales / Flavobacteriaceae / Bizionia The genus Bizionia, a member of the family Flavobacteriaceae , was proposed by Nedashkovskaya et al. in 2005 to accommodate Gram‐negative, strictly aerobic, nonmotile by gliding, and oxidase‐positive bacteria. The close phylogenetic relatives of the genus Bizionia are members of the family Flavobacteriaceae such as Aquaticitalea, Arcticiflavibacter, Corallibacter, Formosa, Geojedonia, Ichthyenterobacterium, Lacinutrix, Olleya, Psychroserpens , and Xanthomarina with sequence similarity ranges of 93.6–96.5, 93.4–95.9, 93–94.8, 93.5–97.2, 93.1–96.1, 93.9–96.5, 92.3–96.4, 93.5–95.8, 91.9–95.5, and 94.2–96.5%, respectively. On marine agar, colonies of the majority Bizionia species are circular, convex, smooth, yellow, with entire edges and golden yellow, orange, yellowish orange, or saffron pigmented. Growth occurs with 0–10% NaCl, at pH 5.5–9.0, and at −2–45°C. The optimal growth is observed with 1–3% NaCl, at pH 7.0–8.0, and at 20–30°C. Bizionia strains cannot hydrolyze agar, chitin, carboxymethylcellulose, starch, and urea, and produce acid from l ‐arabinose and maltose. The predominant cellular fatty acids of the known members of the genus Bizionia are iso‐C 15:0 , anteiso‐C 15:0 , iso‐C 15:1 G, and iso‐C 16:0 3‐OH. The major respiratory quinone is MK‐6. The main polar lipid is phosphatidylethanolamine. At the time of writing, the genus Bizionia comprised 13 species with validly published names that were isolated from the different marine environments including seawater, sea‐ice brines, sediments, and animals. The Bizionia species share 16S rRNA gene sequence similarities ranging from 93.9 to 99% to one another. The DNA–DNA relatedness between the type strains of the Bizionia species is 11–53%.
